2/5
Step-by-step explanation:
Answer:
10/7 feet
Step-by-step explanation:
Let e = Ethan
k = Kayla
The following equations can de derived from the equation :
1/2 e = 2/3k
multiply both sides of the equation by 2
e = 4/3k --- 1
e + k = 10 --- 2
Substitute for e in equation 2
4/3k + k = 10
7/3k = 10
multiply both sides of the equation by 3/7
k = 30/7
Substitute for k in equation 1
e = (4/3) x 30/7 = 40/7
difference in length = 40/7 - 30/7 = 10/7
Answer:
72 cent
Step-by-step explanation:
Well first all you have to do is simplifying both sides of the equation then of course isolating the variable then you should end up with
![n = \frac{29}{42}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B29%7D%7B42%7D)

Answer:
Step-by-step explanation:
180 = 2x-8 + 36
152 = 2x
76 = x
now plug it into the given expression
∠A = 2x-8
∠A = 2(76) -8
∠A = 152-8
∠A = 144 °
