Six times a number is equal to the number increased by 15 find the number

3

Step-by-step explanation:

(six times a number) is (equal) to (the number increased by 15)

            6x                          =                            x + 15

6x = x + 15

Subtract x from both sides

5x = 15

Divide both sides by 5

x = 3

part a: 1.08

part b: 27.59

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
