Paul has 12 coins in his pocket, consisting entirely of dimes and quarters. If he has a total of 240 cents in coins, how many coins of each type are in his pocket?.

4 dimes and 8 quarters

Step-by-step explanation:

Let d = number of dimes.

Let q = number of quarters.

d + q = 12

10d + 25q = 240

       -10d - 10q = -120

(+)     10d + 25q = 240

                  15q = 120

q = 120/15

q = 8

d + q = 12

d + 8 = 12

d = 4

4 dimes and 8 quarters

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4

7
