Rain fell on four days in june. these amounts were recorded: 5 mm, 9 mm, 2 cm, and 2.6 cm. what was the total rainfall for june?

question 1: step-by-step explanation:

1/4 of 84 = 84÷4= 21

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
