Answer:
27
Step-by-step explanation:
Multiply 8×.75 (6)
Add that to 21
Answer:
X-----Independent Variable
Y-----Dependent Variable
Dependent Variable-----A variable whose value determines the value of the output
Independent Variable-----A variable whose value determines the value of the input
Input-----The value substituted into an expression or function
Output----The value that results from the substitution of a given input into an expression or function
6 *20 = 120
8 *60 = 480
120 + 480 = 600 pounds total
Let x = the length of the shorter piece
x+x+16=50in
2x=50-16
2x=34
x=17
Then
x+16=17+16
x+16=33
Subtract 16 from both sides
The lengths are 17in and 33in
The 4 7/8 = 39/8 = 13 pieces of string, he needs 20 so he will need to cut 7 more pieces
