Answer:

-.6

Step-by-step explanation:

-2.1 - x = -1 1/2

Change the fraction to a decimal

-2.1 -x = - 1.5

Add 2.1 to each side

-2.1 -x+2.1 = -1.5 +2.1

-x = .6

Multiply each side by -1

x = -.6

Total number of students = 35

Number of male students = 14

% of students that are male = $\frac{14}{35} * 100 = \frac{14}{7} * 20 = 2 * 20$ = 40 %
