How could you rewrite the expression (–3 + 5) + 8 + (–1) using the Associative Property of Addition?

1 answer:

8 0

The associative property of addition states that: "no matter which terms you combine first, it will always result in the same answer.

Another way to combine: (-3 + 5) + 8 + (-1) is -3 + (5 + 8) + (-1), for you will still get the same answer

-3 + (5 + 8) + (-1) can be an answer

My question is in the attachment.<br>

Nikolay [14]

Answer:

5 and 25

Step-by-step explanation:

let the son's age be x then the father's age is x + 20

In 5 years

son = x + 5 and father = x + 20 + 5 = x + 25

Then

x + 25 = 3(x + 5) ← father is three times as old as son

x + 25 = 3x + 15 ( subtract x from both sides )

25 = 2x + 15 ( subtract 15 from both sides )

10 = 2x ( divide both sides by 2 )

5 = x and x + 20 = 5 + 20 = 25

si=on is 5 and father is 25
