Answer:
265.2
Step-by-step explanation:
3(6*13)=234
2*15.6=31.2
234+31.2=265.2
"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

Answer: First Option
Walter needs to make at least 5 more cookies but no more than 40
Step-by-step explanation:
If we call x the number of cookies that Walter needs to make, then we know that the amount of cookies will be:
Then this amount must be greater than or equal to 20 and must be less than or equal to 55 then.
and 
This is:
We solve the inequality for x.
Then the amount of cookies that Walter must make must be greater than or equal to 5 and less than or equal to 40
