Question

the quotient of a number x and 3 is at least 4. Write the word sentence as an inequality. Then solve the inequality.

Answer 1

x÷3 ≥ 4, x ≥ 12

Explanation:

part 1:

the quotient of x and 3 written in math language is x÷3

the phase "at least 4" is the greater than or equal to sign: ≥ 4

then when you put the two parts together, the answer is

x÷3 ≥ 4

part 1:

x ÷ 3 ≥ 4

multiply 3 to each side:

x ÷ 3 *3 ≥ 4 *3

x ≥ 12

and that's the answer!
