Let number of ounces of sugar  which will be used to make 255 cupcakes be x ounces.

\frac{45}{75}=\frac{x}{255}\\\\ \frac{3}{5}=\frac{x}{255}\\\\ x=\frac{255 \times 3}{5}\\\\ x=\frac{765}{5}\\\\ x=153

So, Number of  ounces of sugar  which will be used to make 255 cupcakes = 153 ounces.

Solve for X in the following equations<br><br> 1) 50-4x = 14<br><br> 2) 6(3x-2)+5x = 57
Sliva [168]
1.)    50 - 14 = 4x
x = 50 - 14 divided by 4 = 36/4 = 9. 
                    x = 9

2.)     6(3x) -12 + 5x = 57
           18x + 5x = 57 + 12
               23x=69
                  x = 69 divided 23 = 3
                       x = 3
