Step-by-step explanation:you always do the exponent first, then you multiply that by that two, and then you add 7.
If we know that Pedro bought 1
![\frac{1}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B4%7D%20)
pounds of red sand, and 5
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
pounds of brown sand, and they both cost $4.60, then we just have to add the individual amounts of sand, since they cost the same.
![1 \frac{1}{4} + 5 \frac{1}{2} = 6 \frac{3}{4}](https://tex.z-dn.net/?f=1%20%20%5Cfrac%7B1%7D%7B4%7D%20%2B%205%20%20%5Cfrac%7B1%7D%7B2%7D%20%3D%206%20%20%5Cfrac%7B3%7D%7B4%7D%20)
So Pedro bought
![6 \frac{3}{4}](https://tex.z-dn.net/?f=6%20%5Cfrac%7B3%7D%7B4%7D%20)
lbs of sand overall. Now, we just need to multiply the cost per pound by the total amount of sand he bought.
![6 \frac{3}{4} * 4.6 = 31.05](https://tex.z-dn.net/?f=6%20%5Cfrac%7B3%7D%7B4%7D%20%2A%204.6%20%3D%2031.05)
Pedro spent $31.05 on sand, which is answer choice B.
Hope that helped =)
8 x (5 x 2 + 3)= 8 x ( 15 + 3) = 8 x 13 = 104.

Answer:
z = ![\frac{50}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B50%7D%7B3%7D)
Step-by-step explanation:
The ratio of corresponding sides are equal, that is
=
( cross- multiply )
12z = 200 ( divide both sides by 12 )
z =
= ![\frac{50}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B50%7D%7B3%7D)
Answer:
longer
Step-by-step explanation:
12 inches is a foot so you need to multiply 12 by 4 which gives you 48 so he needs 4 more inches to have enough string
