Question

28-4d= 5d - 7 what is do

Answer 1

d= 3.88888889

rounded to the nearest tenth= 3.9

rounded to the nearest hundredth= 3.89

Explanation:

28-4d=5d-7 add 7 to both sides

35-4d=5d add 4d to both sides

35=9d divide both sides by 9

3.88888889=d

3.89=d

3.9=d

Answer 2

d = 35/9

Explanation:

28-4d= 5d - 7

Add 4d to each side

28-4d+4d= 5d +4d- 7

28 = 9d-7

Add 7 to each side

28+7 = 9d-7+7

35 = 9d

Divide each side by 9

35/9 = 9d/9

d = 35/9
