Barbara is 46 inches (in.) tall. She is 2 in. less than 2 3 \frac{2}{3} 3 2 of Alejandro's height (a). Which equation should be used to calculate Alejandro's height?

2 3 a − 2 = 46 \frac{2}{3}a-2=46 3 2 a − 2 = 4 6

2 a + 2 3 = 46 2a+\frac{2}{3}=46 2 a + 3 2 = 4 6

2 3 ( a − 2 ) = 46 \frac{2}{3}\left(a-2\right)=46 3 2 ( a − 2 ) = 4 6

2 ( a + 2 3 ) = 46 2\left(a+\frac{2}{3}\right)=46 2 ( a + 3 2 ) = 4 6

Four years of college will cost Janette $30,000. Each year of college will cost the same amount. Janette will receive a one-time scholarship of $2,000. She will borrow y dollars in loans each year to pay for the remaining cost. Which equation can be used to calculate the amount of money she will need to borrow for her 4 years of college?

30 , 000 = 2 , 000 ( 4 + y ) 30,000=2,000\left(4+y\right) 3 0 , 0 0 0 = 2 , 0 0 0 ( 4 + y )

30 , 000 = 4 ( 2 , 000 ) + y 30,000=4\left(2,000\right)+y 3 0 , 0 0 0 = 4 ( 2 , 0 0 0 ) + y

30 , 000 = 4 ( y + 2 , 000 ) 30,000=4\left(y+2,000\right) 3 0 , 0 0 0 = 4 ( y + 2 , 0 0 0 )

30 , 000 = 4 y + 2 , 000 30,000=4y+2,000 3 0 , 0 0 0 = 4 y + 2 , 0 0 0
