Step-by-step explanation:
Question #1:
7 tomatillos are required to make 12 ounces of enchilada sauce.
[tex]\frac{7}{12}[/tex] tomatillos will be required to make 1 ounces of enchilada sauce.
[tex]\frac{[tex]7times18[/tex]}{12}[/tex] tomatillos will be required to make 18 ounces of enchilada sauce.
Hence, 10.5 tomatillos will be needed to make 18 ounces of enchilada sauce.
Question #2:
The printer does 11 color pages in 2 minutes.
In 1 minute it does 5.5 color pages.
In 7 minute it does [tex]7times5.5[/tex] = 38.5 color pages.
Question #3:
Given that [tex]\frac{18}{24} = \frac{b}{12}[/tex].
b = [tex]\frac{18times12}{24}[/tex] = 9
Question #4:
Since, y and x have a proportional relationship, y = [tex]ktimesx[/tex], where k is a constant.
Putting y = 12 and x = 8 in the above equation, we get k = [tex]\frac{12}{8}[/tex] = [tex]\frac{3}{2}[/tex].
It is given y = 18, now x = [tex]\frac{y}{k}[/tex] = [tex]\frac{18}{\frac{3}{2} }[/tex] = 12
Question #5:
This question can be easily solved by ratio.
[tex]\frac{3}{x} = \frac{7}{21}[/tex]
x = the number of cantaloupes that Shayna can buy = 9
