Answer: x= 5

Step-by-step explanation: Distribute the -7 into the parentheses, we get 14x+63=133. You then minus 63 on the left side of the equation and on the right side of the equation. You will get 14x=70. You then solve x by dividing 70 by 14 you will get x=5.

How many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water?
RoseWind [281]

Answer:

The number of 1/5 liter glasses that Lin can fill is 7\frac{1}{2}

Step-by-step explanation:

we know that

To find out how many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water, divided 1 1/2 by 1/5

so

1\frac{1}{2} :\frac{1}{5}

Convert mixed number to an improper fraction

1\frac{1}{2}=1+\frac{1}{2}=1\frac{1*2+1}{2}=\frac{3}{2}

substitute

\frac{3}{2} :\frac{1}{5}

Multiply in cross

\frac{5*3}{2*1}=\frac{15}{2}=7.5

Convert to mixed number

7.5=7+\frac{1}{2}=7\frac{1}{2}
