Answer:

x = 3

Step-by-step explanation:

log 10x + log 2 = log 60

Subtract log 2 from each side

log 10x + log 2 -log 2 = log 60 - log 2

log 10x = log 60 - log 2

We know that log a - log b = log (a/b)

log 10 x = log (60/2)

log 10x = log 30

We know log a = log b that a = b

10x = 30

Divide by 10

10x/10 = 30/10

x =3

Answer:

Answer is 7/2 cm

Step-by-step explanation:

1. Set a ratio

$7=\frac{3V}{l*w}:h=\frac{3V}{l*2w}$

2. Move 2w from denominator to LHS (Left hand side) $\frac{7}{2}w=\frac{3V}{l}$

$\frac{7}{2w}=\frac{3V}{l}$

3. The four options are 7/4, 7/2, 14 or 28 cm
