Chi would have two thousand nickels because if 100 nickels is 5% and 100 divided 5 is 20 so a 100 times 20 is 2000
Do 51 and 2.5 then when you get that add 42 to your answer
Answer:
9
Step-by-step explanation:
x = first number
3x = second number
2x = third number
27 = x + 3x+ 2x
27 = 6x
x=4.5 (first number)
3(4.5) = 13.5 (second number)
2(4.5) = 9 (third number)
(4.5 + 13.5 + 9) /3 = 9
Wow after doing all that I realized that all you had to do was 27/3 since there's 3 numbers.

m∠2=59
m∠3=90
m∠4=31
m∠5=90
hope this helps brainliest please!
