=(-5 x 4 x 1)^-2
= (-20)^-2
= 1/(-20)^2
= 1/400
so D then i think
Let x = the amount of grapes that can be bought for 0.40.
Note: By 90 I assume you mean 90 cents. The same for 40.
12/x = 0.90/0.40
0.90x = 12(0.40)
0.90x = 4.80
x = 4.80 ÷ 0.90
x = 5.33333
We can round the decimal to the ones place to get 5 grapes.
Step-by-step explanation:
y = 2x
if x = 1 y = 2(1) = 2
if x = 2 y = 2(2) =4
