Answer:
A) N + Q = 130
B) .05N + .25Q = 15.90
Multiplying equation A by -.05 equals
A) -.05N -.05Q = -6.50 then adding this to B)
B) .05N + .25Q = 15.90 Equals
.20Q = 9.40
Quarters = 47
Nickels = 83
.05*83 + .25*47 = 4.15 + 11.75 = 15.90

Answer: 1150 turns
Step-by-step explanation: radius of wheel is 0,9 m
In one turn wheel moves 2·pi·0,9 m = 5,652 m
You divide 6500 m : 6,652 m = 1150

Answer:
124
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180:
m<R + m<S + m<T = 180
11x + 3 + x + 15 + 2x + 8 = 180 add like terms
14x + 26 = 180 subtract 26 from both sides
14x = 154 divide both sides by 14
x = 11 to find m<R replace x with 11
11*11 + 3 = 124
