Step-by-step explanation:
Answer:
16 quarters
30 pennies
Step-by-step explanation:
q= quarters
p=pennies
set up a system of equations. One equation is for total value, the other is total # of coins.
q + p = 46
0.25q + 0.01p = 4.30 -> multiply this equation by 4 so you can subtract from the top equation
q + P =46
1q + 0.04p = 17.20
subtract the bottom equation from the top
0.96p = 28.8
divide by 0.96
p=30
substitute p in the top equation
q + 30 = 46
subtract 30 from both sides
q = 16
Answer:4.36?
Step-by-step explanation:
distance or area?
A=lw
48=11L
4.36=l
50 because 80+50+x=180 (inside triangle) x=130 180-130= 50 (angle outside triangle)
