Which equation is equivalent to

Paul [167]

Answer:

c) 3x - 45 = 10

Step-by-step explanation:

$\frac{1}{5}x-3=\frac{2}{3}\\\\\frac{1}{5}x-\frac{3*5}{1*5}=\frac{2}{3}\\\\\frac{x-15}{5}=\frac{2}{3}\\$

Cross multiply,

3*(x - 15) = 2*5

3*x - 3*15 = 10

3x - 45 = 10

If a concrete mix contains 1-1/2 cubic feet of gravel, 1/2 cubic foot of water,

Karolina [17]

Answer:

The correct answer is "50%".

Step-by-step explanation:

The given values are:

Gravel,

= $(1-\frac{1}{2} )$

Water,

= $\frac{1}{2}$

Cement,

= 1

Sand,

= 2

Now,

The total mixture will be:

= $Gravel+Water+Cement+Sand$

By substituting the values, we get

= $(1-\frac{1}{2} )+\frac{1}{2} +1+2$

= $\frac{1}{2} +\frac{1}{2} +1+2$

= $4 \ cubic \ feet$

hence,

The percentage of sand will be:

= $\frac{Sand}{Total}\times 100$

= $\frac{2}{4}\times 100$

= $50$ %
