10x + 7y=1<br> -5x-7y=24
nikitadnepr [17]
Okay, so since both y values share the same number, let's add both equations so the y values cancel out leaving us to solve for x.

10x+(-5x)=5x

7y+(-7y)=0

1+24=25

Now we have 5x=25

divide both sides by 5 and we have x=5

Now that we know x=5, we can plug it into one of the problems to find y.

Let's do 10(5) +7y=1   

50+7y=1  subtract 5 and we get 7y=-49

divide -7 from both sides and we get y=-7

so there you have it x=5 and y=-7

Liquid A has a density of 0.7g/cm^3
TiliK225 [7]
\rho = \frac{m}{V} \Rightarrow V=\frac{m}{\rho}
ρ - density, m - mass, V - volume

Liquid A:
\rho=0.7 \ \frac{g}{cm^3} \\&#10;m=140 \ g \\&#10;\\ V=\frac{140 \ g}{0.7 \ \frac{g}{cm^3}}=200 \ cm^3

Liquid B:
\rho=1.6 \ \frac{g}{cm^3} \\&#10;m=128 \ g \\&#10;\\ V=\frac{128 \ g}{1.6 \ \frac{g}{cm^3}}=80 \ cm^3

Liquid C:
m=140 \ g + 128 \ g=268 \ g \\&#10;V=200 \ cm^3 + 80 \ cm^3=280 \ cm^3 \\ \\&#10;\rho=\frac{268 \ g}{280 \ cm^3} \approx 0.96 \ \frac{g}{cm^3}

The density of liquid C is approximately 0.96 g/cm³.
