Step-by-step explanation:
20. First find the values of the numbers being added.
![(\frac{3}{4})^3 = \frac{27}{64}](https://tex.z-dn.net/?f=%28%5Cfrac%7B3%7D%7B4%7D%29%5E3%20%3D%20%5Cfrac%7B27%7D%7B64%7D)
![(\frac{5}{8} )^2 = \frac{25}{64}](https://tex.z-dn.net/?f=%28%5Cfrac%7B5%7D%7B8%7D%20%29%5E2%20%3D%20%5Cfrac%7B25%7D%7B64%7D)
These numbers have a common denominator, so you can add the numerators
27 + 25 = 52
so the number comes out to ![\frac{52}{64}](https://tex.z-dn.net/?f=%5Cfrac%7B52%7D%7B64%7D)
to simplify, divide the numerator and denominator by 4.
So the final fraction becomes ![\frac{13}{16}](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B16%7D)
However the question doesn't have this answer and now I am confused. I assumed that the expression was
but the picture is a little bit blurry and I have bad eyesight so let me know if it is not. I'm too tired to delete this so next problem.
21.
4x + 8x + 7 + 4
Combine the like terms to get the expression
12x + 11 the answer is c.
Answer:
-1000
Step-by-step explanation:
Since there's a negative in the equation, the answer is also a negative. This is also like 20 x 50, but you have to put a negative at the back.
Answer:
Step-by-step explanation:
It says Renita takes minutes to ride half a mile.
She leaves 30 minutes before school.
Total distance is
![2\frac{1}{2} = \frac{1}{2}+ \frac{1}{2} +\frac{1}{2} +\frac{1}{2} +\frac{1}{2}\\](https://tex.z-dn.net/?f=2%5Cfrac%7B1%7D%7B2%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2B%20%5Cfrac%7B1%7D%7B2%7D%20%2B%5Cfrac%7B1%7D%7B2%7D%20%2B%5Cfrac%7B1%7D%7B2%7D%20%2B%5Cfrac%7B1%7D%7B2%7D%5C%5C)
In
![2\frac{1}{2} \ there \ are \ 5 \ times \ \frac{1}{2} \ mile .\\](https://tex.z-dn.net/?f=2%5Cfrac%7B1%7D%7B2%7D%20%5C%20there%20%5C%20are%20%5C%205%20%5C%20times%20%20%5C%20%20%5Cfrac%7B1%7D%7B2%7D%20%5C%20mile%20.%5C%5C)
Therefore total time to reach school will be 5 x 5 = 25minutes.
Since she leaves 30minutes before school. She will reach 5minutes early before school.
