3/x=15/40
solve for x
multiply both sides by x
3=15x/40
multiply both sides by 40
120=15x
dvide both sdies by 15
8=x
the answer is 8
or you could simplifyy 15/40 to get 3/8

Answer:
1.292 x 10^7 cm^2
Step-by-step explanation:
Since the area of a rectangle is A = L x W and you are given the area and one side, you can rearrange this equation to solve for the other:

Therefore the length of the other side is 6 x 10^6.
The perimeter of a rectangle is P = 2L + 2W. We can solve that now that we have the length of the sides:

Answer:
18
Step-by-step explanation:
x-5=(x+8)/2
x-5=x/2+4
add 5
x=x/2+9
subtract x/2
x/2=9
times 2
x=18
