One month Alonzo rented 6 movies and 5 video games for a total of $56. The next month he rented 2 movies and 3 video games for a
total of
$26. Find the rental cost for each movie and each video game.
1 answer:
1st equation: 6m +5v = 56
2nd equation: 2m + 3v = 26
multiply 2nd eq. by 3
3rd equation = 6m +9v =78
subtract 1st from 3rd: 4v = 22
v = 22/4 = 5.5 so videos cost 5.50 each
now use 1st eq. to solve for m:
6m +5(5.50) = 56 =
6m + 27.50 = 56=
6m = 28.5
m = 28.5/6 = 4.75 each movie
video cost 5.50
movie cost 4.75

![-3d + 10 = 43](https://tex.z-dn.net/?f=-3d%20%2B%2010%20%3D%2043)
Solution:
1) Switch +10 to -10 and subtract -10 in each side.
Example:
43-10= 33
2) You will be left with
![-3d=43](https://tex.z-dn.net/?f=-3d%3D43)
3) Divide
![\frac{43}{-3d}](https://tex.z-dn.net/?f=%20%5Cfrac%7B43%7D%7B-3d%7D%20)
4) Your final answer is -11
So, d = -11

Answer:
x=1
Step-by-step explanation:
3^x +1
f(x)=3x+1
f(x) =g(x)
3x +1 =3^x +1
Subtract 1 from each side
3x = 3^x
Let x =1
3*1 = 3^1
3=3
