On number 10, you know that the whole side length is going to be 1/4 of 48 because 9 * 4 = 36. So, you can say that x will be equal to 12, since 1/4 of 48 is 12 and 12*2 + -12 = 12. 

On number 11, you can say that 5x +5 = 40 because that is 5 times 8. So, you can solve for this to get x = 7 by subtracting 5 from both sides and then dividing both sides by 5. Hope this helps and let me know if you have more questions!

Write a proportion you could use to convert 2.5 gallons to quarts.
marusya05 [52]
We know there are 4 quarts in a gallon, so how many quarts in 2.5 gallons anyway?

\bf \begin{array}{ccll}
quarts&gallons\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
4&1\\
x&2.5
\end{array}\implies \cfrac{4}{x}=\cfrac{1}{2.5}\implies \cfrac{4\cdot 2.5}{1}=x
