Hey! :)
10y-3(y+5)
Distribute the -3.
-3*y= -3y -3*5= -15
10y-3y-15
7y-15
"A" is the answer.

Answer:
Board 1 = 1.2m
Board 2 = 2.4m
Board 3 = 3.6m
Step-by-step explanation:
Board 1 = x
Board 2 = 2x
Board 3 = 3x
x + 2x + 3x = 6x
7.2 /6 = 1.2
Board 1 = 1.2
Board 2 = 2 (1.2) = 2.4
Board 3 = 3 (1.2) = 3.6
The answer may be 36 but I am not very sure
Answer:
y = -24
Step-by-step explanation:
Direct variation is
y = kx where k is a constant
12 = k*(-1)
12/(-1) =k
-12 = k
The equation is y = -12x
Let x = 2
y = -12(2)
y = -24
