Stacy and neil painted 280 ft2 of their living room wall with 45 gallon of paint. how many square feet can they paint with 3 gallons of paint?

The number of square  feet that can be painted with 3 gallons of paint is 18.667 ft²

Step-by-step explanation:

Stacy and Neil painted 280 ft² of their living room wall with 45 gallon of paint.

To find the number of square feet that can be painted with 3 gallons of paint,

we will simply use proportion;

Let x = number of square feet that can be painted with 3 gallons of paint

280 ft²     =     45 gallons

   x           =       3 gallons

cross multiply

45  ×   x   =   280  ×    3

45x    =   840

Divide both-side of the equation by 45

45x/45   =  840/45

(on the right-hand side of the equation, 45 at the numerator will cancel-out 45 at the denominator leaving us with just x while on the right-hand side of the equation, 840 will be divided by 45)

x = 18.667 ft²

Therefore, the number of square feet that they can paint with 3 gallons of paint is 18.667 ft²

its 69.420

step-by-step explanation:

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.
