Let T = cost of a taco
Let S = cost of a salad
(2 tacos + 1 salad) + (8 % of 2 tacos and 1 salad) + 3 = 13.80
2T + S + .08(2T + S) + 3 = 13.80
2T + 2.5 + .08(2T + 2.5) + 3 = 13.80
2T + 2.5 + .16T + .20 + 3 = 13.80
2.16T + 5.7 = 13.80
2.16T = 8.10
T = 8.10/2.16 = $3.75
Check: 2T + S + .08(2T + S) + 3 = 13.80
2(3.75) + 2.50 + .08(2(3.75)+2.5) + 3 = 13.80
7.5 + 2.5 + .08(10) + 3 = 13.8
13.80 = 13.80

Try doing 40 - 34 first:
40 - 34 = 6
Now try 34 + 6
34 + 6 = 40
X=6

Answer:
x = 34; y = 14
Step-by-step explanation:
Step 1: Make the equations
x + y = 48
x - y = 20
Step 2: Solve the equations
x + y = 48
x - y = 20
2x = 68
x = 34
34 + y = 48
y = 14
Answer:
6 dimes, 26 nickels
Step-by-step explanation:
The number of nickels is N, and the number of dimes is D.
N + D = 32
5N + 10D = 190
--
N + 2D = 38
D = 6
N = 26
Bowling ball radius = 108 mm
