Answer:

V = 48 cubic units

Step-by-step explanation:

$V=b^{2} \frac{h}{3}$ Use this equation to find the volume

$V=6^{2} \frac{4}{3}$ Simplify the exponent

$V=36(\frac{4}{3})$ Multiply

V = 48 cubic units

28 - 2 (5a - 3) = 47

Alex787 [66]

Answer: $a=-1.3$

Step-by-step explanation:

1) Reorder the terms: $28 + (-3 * -2 + 5a * -2) = 47$

$28 + (6 + -10a) = 47$

2) Solving: $34 + -10a = 47$

3) Add -34 to each side of the equation: $34 + -34 + -10a = 47 + -34$

4) Combine like terms: 34 + -34 = 0: $0 + -10a = 47 + -34$

$-10a = 47 + -34$

5) Combine like terms: 47 + -34 = 13: $-10a = 13$

6) Divide each side by -10: $a = -1.3$
