Translate this phrase into an algebraic equation:

A number tripled subtracted from 60 is the same as 21.

• 3c − 60 = 21

• 60 − 3 = 21c

• 60 − 3c = 21

• c(60 − 3) = 21

Translate the sentence into an inequality. Seven subtracted from n is greater than or equal to 18.

• n - 7 > 18

• 7 - n ≥ 18

• n - 7 ≥ 18

• n + 7 ≥ 18

Find the Error
What error did the student make when solving the equation:
1/5x + 6 = 3/5x + 5
1x + 6 = 3x + 5
-2x + 6 = 5
-2x = -1
x = 1/2

• The student found an incorrect common denominator

• The student did not multiply all terms by the common denominator

• The student did not use opposite operations appropriately

• The student did not correctly eliminate the variable from one side of the equation

²/₃(5x + 6) = 34

• 51

• 45

• 8

• 9
