Answer:15
Step-by-step explanation: this is an equilateral triangle and 45-15-15=15 so no matter what it would be 15
The formula for x in terms of w is x = 3w² and the formula for y in terms of x is y = (1/112)x³
<h3>Variation</h3>
x = k × w²
w = 4, x = 48
48 = k × 4²
48 = k × 16
48 = 16k
k = 48/16
k = 3
So,
x = k × w²
x = 3 × w²
x = 3w²
y = k/x³
x = 2, y = 14
14 = k / 2³
14 × 2³ = k
14 × 8 = k
112 = k
So,
y = k/x³
y = 112/x³
y = (1/112)x³

Let x represent the number of 12 packs
Let y represent the number of 6 packs
12x+6y=120
Rearrange for x
12x=120-6y
X=10-1/2y
Rearrange for y
6y=120-12x
Y=20-2x
Hope this helps!
