Answer:
48% of people do NOT like walking
Step-by-step explanation:
First, write it as a fraction 13/25 (People who like jogging)
We want to find out the number of people who DON'T like walking, so we subtract 25-13=12. Put 12/25.
Lastly, convert into a percentage. Percent is out of 100, so we need to make the fraction out of 100. To do this multiply the numerator and the denominator by 4. 48/100.
=
48%
Hope this helps,

Answer: 804
Step-by-step explanation:
Answer:
-12y + 20
Step-by-step explanation:
First, you simplify each term:
apply the distributive property:
4 - 5y - 2 (3.5y) - 2 x -8
Multiply 3.5 by -2:
4 - 5y - 2 (3.5y) - 2 x -8
Multiply -2 by -8:
4 - 5y - 7y +16
Next, we simplify by adding terms:
Add 4 + 16:
-5y - 7y + 20
Subtract 7y from 5y:
-12y + 20
Hence the simplified form is -12y + 20
16 goes into 75 4 times, with a remainder of 11.
75/16 = 4.6875
4 x 16 = 64
75 - 64 = 11
