Answer:
8
Step-by-step explanation:
An easy way to solve this problem is by first finding 10%. To find 10% of any number simply move the decimal one place to the left. So 160.0 becomes 16.00. Then, because 5% is half of 10% to find the answer divide 16 by 2. Therefore, Sofia made 8 of her 160 free throws.
OK. Great. Thanks for sharing. Do you have a question to ask ?
My hunch is that you want to know what the "number" is.
Here's how to set it up and solve it:
"a number" . . . . . . . . . . . . . . . Q
"The difference of
a number and 17" . . . . . . . . . . Q - 17
"eight times the difference" . . . 8 (Q - 17)
"is thirty" . . . . . . . . . . . . . . . . . . 8 (Q - 17) = 30
Eliminate parentheses on the left side:
8Q - 136 = 30
Add 136 to each side: 8Q = 166
Divide each side by 8 : Q = 20.75
Answer:
B. -2t^2 + 3t - +4 is the answer.
0.5;0.5;3/
16;5/48 that would be how to do it
