Solve the system of equation: y = x + 5 ; y = 2x +2 x= ? , y = ?

I need this ASAP
It's simple Please!!!!!!!

Answers

Answer 1

Answer:

x = 3

y = 8

Step-by-step explanation:

y = x + 5

y = 2x + 2

They both equal y, so:

x + 5 = 2x + 2

x + 3 = 2x

3 = x

Put the value of x into the equations:

y = 3 + 5 = 8

y = 2(3) + 2 = 8

x = 3

y = 8

Answer 2
so y= 2x + 2
x +5 = 2x +2
5 - 2 = 2x - x
3 = x

Answers

answer: 1/7

the formula for slope is rise over run, or y1-y2 divided by x1-x2. we can choose either number as y1 or y2 but it needs to stay consistent with x

so let’s plug in from your table.

0-1 divided by -7 -0
(you could also do 1-0 divided by 0-(-7))

-1/-7 which equals 1/7

so, your slope is 1/7

Explain why 10 - 8 - 2 has a different answer to 10 - (8-2)
Explain why 10 + 8 - 2 is the same as 10 + (8 - 2)
Why is addition the same when parentheses is added to the subtraction 8 - 2, but subtraction is not the same?

Answers

Answer:

see explanation

Step-by-step explanation:

10 - 8 - 2 ← perform the first subtraction

= 2 - 2

= 0

while

10 - (8 - 2) ← evaluate parenthesis

= 10 - 6

= 4

Because you do the subtraction in the parentheses first. Like 10-(8-2)=10-6=4 but 10-8-2=10-10=0

But when it is 10+(8-2) you just add everything together

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder

Arwa is playing 'Guess my number'. Arwa says: 'If I add 0.4 to my number, divide the answer by 8, then multiply that answer by 9, I get 0.9.' What is Arwa's number?

Answers

0.4 is the answer because you if you work backwards and use inverse operations you get 0.4.
meaning, if you divide 0.9 by 9, you get 0.1. when you multiply 0.1 and 8 you get 0.8. and when you subtract 0.4 from 0.8 you get your answer, 0.4.

whats the surface area?

whats the surface area?

Answers

Answer:

  1108 in²

Step-by-step explanation:

You want the total surface area of the pentagonal prism shown.

Base area

The area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...

  A = LW +1/2bh

  A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches

Lateral area

The lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.

  LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches

Total area

The total surface area of the figure is the sum of the two base areas and the lateral area:

  SA = 2(114 in²) +880 in² = 1108 in²

The surface area of the composite figure is 1108 in².

On a piece of paper, use a protractor to construct a triangle with angle measures of 30° and 40°.

Select from the drop-down menu to correctly classify the triangle.

A triangle with angle measures of 30° and 40° is

Acute
obtuse
right

Answers

Step-by-step explanation:

The answer is b. an obtuse. This is because if it were a right-angled triangle, then 90 + 30 + 40 would equal 180 and it doesn't. It's obtuse because 30 + 40 = 70, and triangles have to add up to 180° so the last angle would need to be 110°, which is an obtuse angle. I hope this helps!

An angle smaller than 90° is gonna be a acute so your answer is gonna be acute

The data given represents the number of gallons of coffee sold per hour at two different coffee shops.


Coffee Ground
1.5 20 3.5
12 2 4
11 7 2.5
9.5 3 5
Perks A Lot
10 3.5 3
5 2.5 7
8 5.5 9.5
6 9 4.5


Compare the data and use the correct measure of center to determine which shop typically sells the most amount of coffee per hour. Explain.
Perks A Lot, with a mean value of 6.125 gallons
Perks A Lot, with a median value of 6.125 gallons
Coffee Ground, with a mean value of 6.75 gallons
Coffee Ground, with a median value of 6.75 gallons

Answers

The answer is .c. Brainlist pls
To compare the amount of coffee sold per hour at the two coffee shops, we need to calculate the measures of center for each shop. The measures of center are the mean and median.

To calculate the mean, we add up all the values and divide by the total number of values. To calculate the median, we arrange the values in order from smallest to largest and find the middle value. If there are an even number of values, we take the average of the two middle values.

Using these methods, we get:

For Coffee Ground:
Mean = (1.5 + 20 + 3.5 + 12 + 2 + 4 + 11 + 7 + 2.5 + 9.5 + 3 + 5) / 12 = 6.75 gallons
Median = (2 + 2.5 + 3 + 3.5 + 4 + 5 + 7 + 9.5 + 11 + 12 + 20 + 9.5) / 2 = 6.75 gallons

For Perks A Lot:
Mean = (10 + 3.5 + 3 + 5 + 2.5 + 7 + 8 + 5.5 + 9.5 + 6 + 9 + 4.5) / 12 = 6.125 gallons
Median = (3.5 + 3 + 4.5 + 5 + 5.5 + 6 + 7 + 8 + 9 + 9.5 + 10 + 2.5) / 2 = 6.125 gallons

Based on these calculations, we can see that both shops have the same median value of 6.75 gallons. However, the mean value for Coffee Ground is slightly higher at 6.75 gallons compared to Perks A Lot's mean value of 6.125 gallons.

Therefore, we can conclude that Coffee Ground typically sells the most amount of coffee per hour, based on the mean value. However, since the median values are the same for both shops, it's possible that there is some variability in the amount of coffee sold at each shop, and further analysis may be necessary to make a more definitive conclusion.

How can I find the cube root of 64?

Answers

Answer:

4

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

andre is traveling from jeffersonville to springfield. he plans to stop for a break when the distance he has traveled and the distance he has left to travel have a ratio of 3:7. where should andre stop for his break? jeffersonville, J (-15, 2). springfield, S (25, 17)

Answers

Answer:

Andre should stop at (-3 , 6.5)

Step-by-step explanation:

The change in x is from -15 to 25 which is 40 units. 40 x 3/10 = 12 which means Andre moves 12 units right starting from -15 so the x coordinate is -15+12 = -3

The change in y is from 2 to 17 which is 15 units. 15 x 3/10 = 4.5 which means Andre moves 4.5 units up starting from 2 so the y coordinate is 2+4.5 = 6.5.

she should stop at (-3, 6.5 )

Answer 19:- x = 5

Answer 20:- x = 11

Step-by-step explanation:

Answer 19:-

2x + 10 = 20

2x = 10

x = 5

Answer 20:-

80 + 20x = 300

20x = 220

x = 11

Answer:

19. x = 5

This is because Elise need $20, so we are going to figure out x

First, subtract 10 by both sides

2x = 10

Then, divide both sides by two to isolate the variable

x = 5

5 cars is the minimum

================================================================

First we subtract 80 by both sides

20x = 220

Then we isolate the variable by dividing both sides by 20
