60 total fourth graders and 43 are girls. To find the number of boys, subtract.

60 - 43 = 17 boys

If 5 girls were absent, subtract.

43 - 5 = 38 girls present

If 4 boys were absent, subtract.

17 - 4 = 13 boys present

Therefore, there were 13 boys present.

Best of Luck!

The question is:

Naddik [55]

Answer:

2.5 gallons of the 20% solution must be replaced by the 36% solution.

Step-by-step explanation:

$.12(20 - x) + .36x = 20(.15)$

$2.4 - .12x + .36x = 3$

$2.4 - .24x = 3$

$- .24x = - .6$

$.24x = .6$

$x = 2.5$
