Tommy wants to install 2 lights in his room against the wall 20 feet long. One light will be 3 feet above the height of his desk and the other 5 feet above. He needs to know where on the wall, at desk height, he should place the light switch to minimize the amount of electrical wire needed, he's on a budget. Where should tommy place the light switch from the left corner on the 20 ft wall?

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

9 x 8 divided by (5-3)=36
