Answer:
y = 40 x = 80
Step-by-step explanation:
520 = 3.25x + 6.5y x+y=120
x+y=120
x = 120-y
520 = 3.25(120-y)+6.5y
520 = 390-3.25y+6.5y
520 = 390+3.25y
130=3.25y
Divide each side by 3.25
40 = y
x = 120-y
x = 120-(40)
x = 80
Answer:
C. ![66.7m/s^{2}](https://tex.z-dn.net/?f=66.7m%2Fs%5E%7B2%7D)
Step-by-step explanation:
We sholud also talk about medium aceleration
![a_{m} =\frac{V_{f}-V_{i}}{t_{f}-t_{i}} = a_{m}=\frac{54-4}{0.75-0} = 66.7m/s^{2}](https://tex.z-dn.net/?f=a_%7Bm%7D%20%3D%5Cfrac%7BV_%7Bf%7D-V_%7Bi%7D%7D%7Bt_%7Bf%7D-t_%7Bi%7D%7D%20%3D%20a_%7Bm%7D%3D%5Cfrac%7B54-4%7D%7B0.75-0%7D%20%3D%2066.7m%2Fs%5E%7B2%7D)

Answer:
or ![x = 25.531...](https://tex.z-dn.net/?f=x%20%3D%2025.531...)
Step-by-step explanation:
<u>Step 1: Cross Multiply</u>
<u />![\frac{5}{2.35} = \frac{x}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B2.35%7D%20%3D%20%5Cfrac%7Bx%7D%7B12%7D)
![5(12) = 2.35(x)](https://tex.z-dn.net/?f=5%2812%29%20%3D%202.35%28x%29)
![60 = 2.35x](https://tex.z-dn.net/?f=60%20%3D%202.35x)
<u>Step 2: Divide both sides by 2.35</u>
<u />![60 / 2.35 = 2.35x / 2.35](https://tex.z-dn.net/?f=60%20%2F%202.35%20%3D%202.35x%20%2F%202.35)

Answer: Jim had $28 , Kirk had $16
Step-by-step explanation:
Let's represent the amount of money they had initially as k and j respectively.
From the first statement, Kirk has 12 dollars less than Jim. Mathematically, this could be expressed as :
K + 12 = J or K = J - 12
From the second sentence, we can deduce the following : If Jim's initial amount is halved, Kirk would be 2 dollars richer. This could he expressed mathematically as ;
J/2 = K - 2
NOW , let's solve both equations simultaneously.
K = J - 12 ..........(i)
J/2 = K - 2 ........(ii)
Let's substitute for k in equation ii using equation I
J/2 = J - 12 - 2
J/2 = J - 14
J = 2J - 28
Rearranging yields
2J - J = 28
J = 28
Since K = J - 12, that means k = 28 - 12 = 16
Hence initially, Jim had $28 while Kirk had $16
Answer is 24p^2 - 6
you get this because you are suppose to use foil
4p x 6p
4p x -3
2 x 6p
2 x -3
when u do all that you get
24p^2 - 12p + 12p -6
combine like terms you get 24p^2 - 6
