PLSSS HELP ASAP
Answers
Answer:
Hope this helps! (:
Step-by-step explanation:
By putting the numbers in the given equation,
2x + 3 + 3x = 7x + 9
5x + 3 = 7x + 9
(5x + 3) - 7x = (7x + 9) - 7x
(5x - 7x) + 3 = 9
-2x + 3 = 9
(-2x + 3) - 3 = 9 - 3
-2x = 6
-x = 3
x = -3
Therefore, our equation is correct which has a negative result.
In place of 6 if we use 8, value of x will be negative again.

What is the radius, in centimeters, of a circle that has a circumference of 16π?
8
16
32
64
Answers
Answer: The radius equals 8cm
Answer:
8
Step-by-step explanation:
The circumference of a circle is equal to π , which is a number ≈ 3.14 , multiplied by the diameter of the circle.
Therefore, C = π d .
We know that the circumference, C , is 16 π , so we can say that:
16 π = π d
We can divide both sides by π to see that 16 = d .
We now know that the diameter of the circle is 16 .
We also know that the diameter has twice the length of the radius.
In equation form: 2 r = d
2 r = 16
r = 8
Note that since 2 r = d , the equation C = 2 π r holds and can be used in place of C = π d .

A rectangle with length of 12 feet and width 4 feet. A diagonal cuts the rectangle into two halves. One of the triangular halves is shaded.
2(12 + 4) = 32
fraction 1 over 2(12 + 4) = 8

fraction 1 over 2(12 × 4) = 24
I'll mark as brainliest
Answers
Answer:
It is \(\frac{1}{2}\) (12 × 4) = 24
Step-by-step explanation:
\(\frac{1}{2}\) (base × height) = area of triangle
\(\frac{1}{2}\) (12 × 4) = area
area = 24

Step-by-step explanation:
Answer:
Step-by-step explanation:
The equation y=7x+1 is written in slope intercept form. That would be:
y=mx+b
m is the slope
b is the y intercept, or where the line first is seen on the y axis.
Because b=1, the y intercept is 1.
Because m=7, the slope is 7.
STEP 1: GRAPH THE Y INTERCEPT.
Since b=1, the line crosses the y intercept when y=1. So graph y=1 on the coordinate plane.
STEP 2: GRAPH THE SLOPE
Do this by going up 7, then right 1. Because 7 is a positive number, you go up.

Marcus needs 12 cups of edible flowers to make the breakfast mixture to feed the zoo's emperor tamarin monkey troop for the week. The number of cups of edible flowers the zoo has in storage is represented by the expression 1.875c−(c+0.5d). If c=25 and d=20, does Marcus have enough edible flowers to make the breakfast mixture for the emperor tamarin monkeys?
No, because 1.875(25)-((25)+0.5(20))=11.875, which is less than 12.
No, because 1.875(25)−((25)+0.5(25))=9.375, which is less than 12.
No, because 1.875(20)−((25)+0.5(20))=2.5, which is less than 12.
No, because 1.875(20)−((20)+0.5(25))=5, which is less than 12.

Geometry
Answer with a proper explanation
Answers
Answer:
15 sides
Step-by-step explanation:
As we know the full angles of a polygon is 360°
And
Each side has angle 24°
So,
n = 360/24
n = 15 sides
I hope my answer helps you.
The polygon has 5 sides.
Step-by-step explanation:
Given in the diagram, the angle between the ends of each side is given i.e. 24degrees between ends of a side from the centre. Or it can also be said that each side of the polygon subtends an angle at the centre 'O' i.e. each 24*.
=> We know that sum of angles around a point = 360*, so sum of angles around centre = 360*
And 24* in the centre subtends a side of the polygon;
Using the logic - no. of sides = 360*/24* = 15 = 15 sides

Answer:
[ 2] − | −5 + 7 |
Step-by-step explanation:
Since we know that | −5 + 7 | is an absolute value, we know that the answer will be positive no matter what.
Step 1) Solve. | −5 + 7 | = 2.
Step 2) Find which other absolute value is equal to -2.
After solving [2], − | −5 + 7 | = -2, we know that the answer is choice 2.
We know this because | −5 + 7 | = 2, however, since it is multiplied by (-), it becomes -2. And 2 + (-2) = 0
We start by simplifying | −5 + 7 |:
| −5 + 7 | = | 2 | = 2
Now we can simplify each of the answer choices:
[2] | +5 − 7 | = | −2 | = 2
[3] | −( −5 + 7 ) | = | 2 | = 2
[4] | 7 − 5 | = | 2 | = 2
We see that only choice [2], when added to | −5 + 7 |, will equal zero:
2 + (−2) = 0
Therefore, the answer is [2] | +5 − 7 |.

Where would -4,9 be on a coordinate grid
A-1st
B-2nd
C-3rd
D-4th
Answers
The x-coordinate represents the horizontal position of the point, while the y-coordinate represents the vertical position of the point.
In this case, the x-coordinate is -4, which means the point is 4 units to the left of the origin. The y-coordinate is 9, which means the point is 9 units up from the origin.
Therefore, the point (-4,9) is located in the 2nd quadrant of the coordinate grid, since it is to the left of the origin (in the negative x-direction) and above the origin (in the positive y-direction).
So, the correct answer is B-2nd.
