Answer:
Plug the ordered pair (2,5) into the given equation, if it makes the equation true, then it is a solution.
Step-by-step explanation:
y = 2x + 3
substituting : 5 = 2(2) + 3
5 = 4 + 3
5 = 7, this is false, therefore (2,5) is NOT a solution
Answer:
A linear equation's solution would be a coordinate when the value of x and y satisfies the equation.
For Example:
\((1,7)\) will be a solution to the equation \(y=3x+4\), because if you replace x and y with one and seven it satisfies the equation.
\(y=3x+4\\y=7 \\x=1\\\text {Solve: }\\7=3(1)+4\\\rightarrow3*1=3\\7=3+4\\\boxed {7=7}\)
\((1,7)\) also lies on the equation's line.

Given the inequality 5(n − 4) < 4(n + 15), determine which integer makes the inequality false.
S:{80}
S:{15}
S:{5}
S:{−9}
Answers
Answer:
-9
Step-by-step explanation:
5(-9-4)
5(-13)
-65
4(-9+15)
4(6)
24
-65<24 so -9 is false because -65 is not smaller than 24
The solution is Option A.
The value of n which makes the inequality 5 ( n − 4 ) < 4 ( n + 15 ) false is when n = 80
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is given by
5 ( n − 4 ) < 4 ( n + 15 )
Now , on substituting the value of n as 80 in the inequality equation , we get
5 ( n − 4 ) < 4 ( n + 15 )
when n = 80
5 ( 80 - 4 ) < 4 ( 80 + 15 )
5 ( 76 ) < 4 ( 95 )
380 = 380
So , the inequality will become false as the two sides of the equation will result in value 380 when n = 80
Hence ,
The value of n = 80 in the inequality equation 5 ( n − 4 ) < 4 ( n + 15 ) will make it false

Evaulate each expression when n = 2.3
N + 8n2 - 17=
Answers
Answer: 27.62
Step-by-step explanation:
plug in 2.3 wherever 'n' is
I'm assuming that the '2' in 8n2 is an exponent
2.3 + 8(2.3)² - 17 =
Using PEMDAS
start out with exponent since there isn't any parenthesis
(2.3)² = 5.29
2.3 + 8(5.29) - 17
move on to multiplication
8(5.29) = 42.32
2.3 + 42.32 - 17
with addition and subtraction, you do whichever comes first and since this equation starts with addition we'll start there
2.3 + 42.32 = 44.62
then the subtraction
44.62 - 17 = 27.62

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide
Answers
Answer:
To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.
Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).
Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).
To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
First, find out how much stickers you can put on the long side:
12/3 = 4
Next, find out how much stickers you can put on the wide side:
8/2 = 4
Lastly, calculate them together:
4x4=16
So the answer is 16.

Answer:
Option c) 72 cm²
Step-by-step explanation:
In the figure attached we can see a rectangle ABCD with length 12 cm and width 9 cm.
A triangle PEF with height BE and base EF.
Since side AE = 3 cm, so side EB = EC = 9 - 3 = 6cm
and EF = AD = 12 cm
Now we will find the area of of the parts of the card that are not shaded.
Area of parts that are not shaded = Area of rectangle - area of shaded triangle
= (12×9) - 1/2 (BE)(EF)
= 108 - 1/2(6)(12) = 108 - (3)(12) = 72
Option c) 72 cm² is the area of non shaded part.

Answer:
Step-by-step explanation:
The number 1032 is called the numerator or dividend, and the number 43 is called the denominator or divisor.
The quotient of 1032 and 43, the ratio of 1032 and 43, as well as the fraction of 1032 and 43 all mean (almost) the same:
1032 divided by 43, often written as 1032/43.
1032 divided by 43 in decimal = 24
1032 divided by 43 in fraction = 1032/43
1032 divided by 43 in percentage = 2400%
Note that you may use our state-of-the-art calculator above to obtain the quotient of any two integers or decimals, including 1032 and 43, of course.
Repetends, if any, are denoted in ().
The conversion is done automatically once the nominator, e.g. 1032, and the denominator, e.g. 43, have been inserted.
The quotient and remainder of 1032 divided by 43 = 24 R 0
The quotient (integer division) of 1032/43 equals 24; the remainder (“left over”) is 0.
1032 is the dividend, and 43 is the divisor.

First, the blue can be calculated as V=4x32x10= 1280in^3
the second seems as if it is missing a length. However, since we can see that the blue box sits perfectly on the purple, it is safe to assume that the missing length is 10.
Hence, the volume can be calculated as V=12x16x10= 1920in^3

Answers
Answers: statements 1, 2, 6 and 7
=======================================================
Explanation:
I'll briefly go through each statement to mention why it's true or false.
This one is a bit tricky. Some math books define the natural numbers to be N = {1, 2, 3, ...} where 0 isn't included, while other textbooks include 0. The inclusion/exclusion of zero seems arbitrary and depends on other context of the math theorems used. The set of whole numbers is more consistent and it is W = {0, 1, 2, 3, ...} basically it's the definition of natural numbers where 0 is included. So if 0 is defined to be a natural number in your textbook, then statement 1 is true. Otherwise, it's false.This is true. A rational number like 2/3 isn't a whole number, but something like 3/1 = 3 is a whole number. Any whole number can be written as itself over 1.This is false. An integer like -7 is not in the set of natural numbers.This is false. The very definition of "irrational" means "not rational". The two types of numbers are complete opposites. An irrational number is one where we cannot write it as a ratio of integers. A famous example is pi = 3.14... as we can't write it as a fraction of integers. An approximation could be something like 22/7, but we don't capture the full picture of what pi really is.This is false. Refer to question 4 above. The set of rational numbers vs irrational numbers do not overlap at all.This is true. Refer to questions 4 and 5. This is true. We can write any integer as itself over 1. For example, the integer -12 is the same as -12/1 to show that it is rational. This idea is similar to what I mentioned in question 2.After going through all seven statements, we definitely know that statements 2, 6, 7 are true. Statements 3,4,5 are definitely false.
Statement 1 is the only thing left. If your teacher mentioned 4 true statements, then statement 1 has to be true. This in turn means that your teacher is defining 0 to be a natural number.

a) square
b)square
c)they are the same thing because on all sides they are all the same length meaning the same shape
Step-by-step explanation:
If the cube is sliced horizontally, the cross-section will be a square and if the cube is sliced vertically, the cross-section will be a rectangle.
What is Three dimensional shape?A three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
(a) If the cube is sliced horizontally, the cross-section will be a square.
(b) If the cube is sliced vertically, the cross-section will be a rectangle.
(c) The shapes are different because the direction of the slice is different. Slicing horizontally means the slice is perpendicular to the vertical edges of the cube, resulting in a square cross-section.
Slicing vertically means the slice is perpendicular to the horizontal edges of the cube, resulting in a rectangular cross-section.
The dimensions and orientation of the cross-section depend on the orientation of the slice relative to the edges of the cube.
Hence, If the cube is sliced horizontally, the cross-section will be a square and if the cube is sliced vertically, the cross-section will be a rectangle.
