How do u substitute?
pshichka [43]
Hi again!

2x - y = 80
5y = x

P.S. Are you struggling with Algebra, equations and inequations....my advice to you is to start using Khan Academy. It will help you a lot!

Ok stop talking and let's get to work!

We need to solve 2x - y = 80 for y

2x - y = 80

-y = 80 - 2x

Multiply both sides by -1 because y cannot be negative

-y * -1 = -1(80 - 2x)

y = 2x - 80

Now we can substitute 2x - 80 for y in 5y = x

5y = x

5(2x - 80) = x

Use the distributive property

(5)(2x) + (5)(-80) = x

10x - 400 = x

Add -x on both sides

10x - 400 - x = x - x

9x - 400 = 0

Add 400 on both sides

9x - 400 + 400 = 0 + 400

9x = 400

Divide both sides by 9

9x/9 = 400/9

x = 400/9

To find y, we can substitute 400/9 for x in y = 2x - 80

y = 2x - 80

y = 2(400/9) - 80

y = 800/9 - 80

y = 800/9 - 80/1

y = 800/9 + -720/9

y = (800 - 720)/9

y = 80/9

Thus,

The answers are: y = 80/9 and x = 400/9

As always, it is my pleasure to help students like you

The graph below represents which of the following functions?
erica [24]

This is a more difficult one to explain. Let's start with the line to the right.  It has a slope (m) of \frac{-2}{2} = -1 and a y-intercept of +3 (continue the line to see where it crosses the y-axis). So, the equation of that line is: y = -x + 3 when x ≥ 2. This can also be written as y = 3 - x when x ≥ 2.  The only option that has that equation is A.

Answer: A

One evening Papa John’s sold a total of 33 pizzas topped with pepperoni, sausage, or pepperoni and sausage. There were 29 pizzas
dalvyx [7]

Step-by-step explanation:

So he sold 33.

29 had pepperoni and of these 29, 15 had also sausage. SO first, to find out how many pepperoni pizzas only he sold you have to substract.

29-15= 14

14pepperoni pizzas

15 pepperoni and sausage pizzas.

Now we add 14 + 15 = 29

Now we do 33-29= 4

So the final answer to the question is:

10 pizzas more
