Question

write an equation to find the number of students in mr boggs homeroom if the total number of students is 90

Answer 1

The number of students in Mr. Boggs’s homeroom

is equal to b. Add the total number of students in

each class and set it equal to 90.

90 = b + 1.5(b + 2) + 15 + (2b – 9)

Use the Distributive Property, and collect like terms.

90 = b + 1.5b + 3 + 15 + 2b – 9

90 = 4.5b + 9

Answer 2

$x \times 10$
