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:
B,∠BAC=40°
Step-by-step explanation:
diameter makes 90° on the circumference.
∠CBA=90°
∠ACB+∠CBA+∠BAC=180°
50+90+∠BAC=180
∠BAC=180-140=40°
Answer:
while working on graphs there is an (X,Y) axis
#7 start at 0 then go right 2, up 4
#8 start at 0 then go left 6 then up 8
#9 start at 0 then go right 10 then down 12
#10 start at 0 then go left 14 then down 16
