What does (d+3) represent in 4.5(d+3)=45

Scrat [10]

Answer:

(d + 3) would be 10

Step-by-step explanation:

Step 1: Distribute

$4.5(d + 3) = 45$

$(4.5 * d) + (4.5 * 3) = 45$

$4.5d + 13.5 = 45$

Step 2: Subtract 13.5 from both sides

$4.5d + 13.5 - 13.5 = 45 - 13.5$

$4.5d = 31.5$

Step 3: Divide both sides by 4.5

$\frac{4.5d}{4.5} = \frac{31.5}{4.5}$

$d = 7$

Step 4: Determine what (d+3) is

$(d + 3)$

$(7 + 3)$

$10$

Answer: (d + 3) would be 10
