Your parents are decorating the dining room and want to place two rectangular wall sconce lights that are 25 inches wide along a 10 2/3 foot wall so that the distance between the lights and the distances from each light to the nearest edge of the wall are all the same. design the wall and determine the distance

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
