John who is 20 years old is 8 years older than 2 times the age of carlos. how old is carlos

Carlos is 6

let x be Carlo's age then

2x + 8 = 20 → (solve for x)

subtract 8 from both sides

2x = 20 - 8 = 12

divide both sides by 2

x = = 6

Carlos is 6 years old

c = Carlos

j = John

2c + 8 = j

2c + 8 = 20

2c = 20 - 8

2c = 12

c = 12 : 2

c = 6

6*2+8=20

Since August is the 8th month of the year, this means Kelli has called her grandmother 8 times so far since she calls her once a month

Since she calls her cousin every other month, Kelli has called her cousin 4 times so far because if she calls from January to August every other month, you would do 8÷2 because every other month = 2 months.

This means Kelli has called her grandmother 8 times

Therefore, 8+4=12.

Kelli so far has made 12 calls in total.
