Let n be the smallest of these integers. The other two are then n + 2 and n + 4.

"triple of the sum of thrice the third one and twice the first one is equal to 291" is a long-winded way of saying

3 (3 (n + 4) + 2n) = 291

Solve for n :

3 (3n + 12 + 2n) + 291

3 (5n + 12) = 291

15n + 36 = 291

15n = 255

n = 17

Then the greatest of the three integers is n + 4 = 21.

caitlyn has $210 in her savings account and she has to pay her parents $5 each month.Santos has $90 dollars and he saves $5 doll
nevsk [136]

Answer:

After about 12 months both Caitlyn and Santos will have the same balance of 150 dollars in their bank account.

Step-by-step explanation:

Caitlyn's saving:  -5x+210

Santos' saving: 5x+90

To know when the total amount in their bank account is the same you would need to make these linear equations equal to one another.

-5x+210 = 5x+90

(Add 5x on both sides)

210=10x+90

(Subtract 90 from both sides)

120=10x

(Simplify)

x=12

After about 12 months their total savings should be the same. To check what their balance will be plug the x value of 12 into both of these equations. This should give 150 as your answer for both equations.
