Hey everyone. I need the answer to this ASAP!: Michael knows that 2 cans of paint is the exact amount he needs to paint a 10-foo
Ivahew [28]

Answer:

See attachment for graph

<em></em>

Step-by-step explanation:

Given

2 cans = 10ft\ by\ 12ft

Required

Graph the relationship between both parameters

First, calculate the area;

Area = 10ft * 12ft

Area = 120ft^2

This implies that: (2, 120) i.e. 2 cans for 120ft^2.

So we have:

(0,0) and (2,120)

(0,0) implies that: 0 cans for 0 square feet

Calculate the slope:

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{120 - 0}{2-0}

m = \frac{120 }{2}

m  = 60

The equation is:

y = m(x - x_1) + y_1

So, we have:

y = 60 * (x - 0) + 0

y = 60 * (x )

y = 60 x

gavmur [86]

Answer:

Drinks = 6.75

Popcorn= 1

Step-by-step explanation:

Let the popcorn = P

Let the drink = D

2*P + 3*D = 22.25         multiply this equation by 6

12*P + 4D = 39.00

<u>12P + 18D = 133.5</u>          Subtract these two equations

- 14D = - 94.50               Divide by -14

-14D/-14 = -94.5/-14        Do the division

D = 6.75

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

12P  +  4D = 39            Substitute for D

12P + 4*6.75 = 39        Combine

12P + 27 = 39               Subtract 27 from both sides

12P + 27-27=39-27      Collect like terms

12P = 12                        Divide by 12

12P/12 = 12/12

P = 1                               Answer
