"31-inch piece of steel is cut into three pieces"
Call the pieces a,b,c
a + b + c = 31
"second piece is twice as long as the first piece"
b = 2a
"third piece is one inch more than seven times the length of the first piece"
c = 1 + 7a
Ok, we have our equations, let's substitute the second and third into the first.
a + 2a + 1 + 7a = 31
10a + 1 = 31
10a = 30
a = 30/10 = 3
b = 2a = 6
c = 1 + 7a = 22
Check: 3 + 6 + 22 = 31, good
Answer: 3 inches, 6 inches, 22 inches
First solve the addition part:
5^7 + 5^6 =
78125 + 15625 = 93750
Now divide the total by 6:
93750 / 6 = 15625
Because the answer is a whole number ( no decimal) it is divisible by 6.
To get that percentage you just need to divide 1550 by 200p:
1550/2000 = 0.775
Which means that only 77.5% of the students voted
