7(w+2)+0.5w=5
What is W if the answer is 5?

The answer to your question is w = 1.2

Step-by-step explanation:

Data

Equation                           7(w + 2) + 0.5w = 5

Expand                               7w + 14 + 0.5w = 5

Simplify like terms             (7w + 0.5w) + 14 = 5

                                            7.5w + 14 = 5

Subtract 14 in both sides

                                            7.5w + 14 - 14 = 4 - 15

Simplify

                                            7.5w = - 9

Divide both side by 7.5      7.5/7.5w = 9/7.5

Simplify

                                             w = 1.2      

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
