0.35g would give?

$10 \times 0.35 \div 5 = 0.7cc \: of \: volume$

A piggy bank contains nickels and dimes. There are 160 total coins valuing $10.50. Think about a system of equations that can be

Elodia [21]

$x + y = 160 \\ 0.05x + 0.1y = 10.50$
First, Substitute x + y = 160 into equation
x = 160 - y
$0.05(160 - y) + 0.1y = 10.50 \\ 8 - 0.05y + 0.1y = 10.50 \\ 0.05y = 2.50 \\ y = 50$
Substitute that into
$x + 50 = 160 \\ x = 110$

The answer is 110.

Hope this helps. - M

How do I solve for x?

saveliy_v [14]

$\displaystyle\\\text{The equation is:}\\\\13^2-x^2=15^2-(14-x)^2\\\\13^2-x^2=15^2-(14^2-28x+x^2)\\\\13^2-x^2=15^2-14^2+28x-x^2)\\\\-x^2+x^2-28x=15^2-14^2-13^2\\\\-28x=225-196-169\\ \\-28x=-140~~~\Big|~\cdot(-1)\\\\28x=140\\\\x=\frac{140}{28}\\ \\\boxed{\bf x=5}$
