Answer:
x = -8
Step-by-step explanation:
y = 3x/4
Substitute the value of -6 into y.
-6 = 3x/4
Multiply both sides by 4.
-24 = 3x
Divide both sides by 3.
x = -8.
Answer:
14
Step-by-step explanation:
2x + y = 20 (1)
2x + 3y = 36 (2)
(2) - (1) ⇔ (2x - 3y) - (2x + y) = 36 - 20
⇔ 2y = 16
⇔ y = 8 (3)
From (3) and (1), we have:
2x + y = 2x + 8 = 20
⇔ 2x = 12
⇔ x = 6
So: C = x + y = 6 + 8 = 14
Conclusion : C = 14

Answer:
96 square inches.
Step-by-step explanation:
The formula to finding volume of cube/rectangular shaped objects is:
length x width x height
length = 8
height = 4
width = 3
8 x 4 x 3 = 96
96 square inches
Answer:
