BartSMP [9]

Answer:

148

Step-by-step explanation:

Average = sum of numbers /total numbers

let x = 5th number

123.2 = (118+ 128 + 124,+ 98 + x) / 5

123.2 = (468 + x) / 5

Multiply both sides by 5

616 = 468 + x

x = 148

What is 2/r=12/18?<br> Chcjcjxjxkxkx
Alexeev081 [22]

Answer: r = 3

Step-by-step explanation:

Step 1: Cross-multiply.

2r = 12/18

(2)*(18)=12*r

36=12r

Step 2: Flip the equation.

12r=36

Step 3: Divide both sides by 12.

12r/12 = 36/12

r = 3
