Answer:
m3=15(8)+22=142
m1=19(8)-10=142
Both are equal so the answer is Yes they are parallel
3/4 = .75
4/7 = .57
the answer is : 3/4 > 4/7
Since 20 is a factor of 40, the least common denominator of 3/20 and 9/40 is 40.
Let sister be s. Matthew, M
Matthew is 7years older than twice the age of his sister
M = 7 + 2s
13 = 7 + 2s. 7 crosses the equality to other side and becomes -7
13 - 7 = 2s
6 = 2s Divide both sides by 2
6/2 = 2s/2
3 = s
Sister is 3 years old.
Answer: C
Step-by-step explanation:
You can write each term into a fraction.
becomes 
When you multiply 2 terms with the same base, you add the exponents.

is also the same as ![x\sqrt[5]{x^3}](https://tex.z-dn.net/?f=x%5Csqrt%5B5%5D%7Bx%5E3%7D)
You get this because
. When you pull out 5 os x, you are left with x³ on the inside.
