What expression represents the sum of 8 and twice a number

1 answer:

7 0

Idk if you have any choices or not but it should look like 8 + 2x
How to get the answer: sum means addition, and twice a number is 2 times it. We don't know the number so we'll use x. Two times a number is 2x
And since we are adding we will put an addition sign
8 + 2x

An older person is 4 years older than 7 times the age of a younger person. The sum of their ages is 44. Find their ages

Fynjy0 [20]

Answer:

5 yr and 39 yr

Step-by-step explanation:

Let x = the age of the younger

then 7x + 4 = the age of the older

Now x + 7x + 4 = 44

8x + 4 = 44

8x = 40

x = 5

7x + 4 = 7(5) + 4 = 35 + 4 = 39

Check: 5 + 39 = 44
