It’s easy the answer is 384
Y varies directly with x" means y = constant * x or y = kx ----- (1)1. when x = -1/2, y = 2Put it in (1):2 = k * (-1/2)multiply by 2:4 = k * (-1)4 = -kk = -4y = -4x
"find the value of y when x= -0.3"y = -4x = (-4) * (-0.3) = 1.2
So for each problem, start with y = kxThey give you one x and one y value.Put it in y = kx and find k.Then put x = -0.3 and find y.
Since it is 125/1000 it must be a 5 in the denominator because 5^3=125.
Therefore it is D
Answer:
5.5 feet
Step-by-step explanation:
Divide 18 1/3 by 3 1/3 to get 11/2. Simplify that to 5.5 feet.
70-q-q-2q= 80
combine like terms first
so you get 70-4q= 80
subtract 70 on both sides and you get -4q= 10
divide -4 on both sides and you get q= 10/-4 or -2.5
