If you would like to know how many hours will Lena need to work before she can afford to buy the computer, you can calculate this using the following steps:
$900 - $473 = $427
$427 / $7 = 61 hours of yard work
Result: Lena will need to work 61 hours before she can afford to buy the computer.

Answer:
4/(x + 3)(x + 2)
Step-by-step explanation:
8x - 2 / (x + 3)(x - 1)(x + 2) =
4(x - 1)/(x + 3)(x - 1)(x + 2) =
4/(x + 3)(x + 2)

There is a rule, that says:
sum of angle measures is always equal to 180 degrees.
thats why:
1) total degrees =180 = 45 + 90 + x
so x = 180 - 45 - 90= 45 degrees
the answer is that you can have unlimited number of triangles with those measures (different lengths of sided of triangles, but third angle has to have 45 degrees)
2) 180 = 67 + 27 + x
x = 180 - 67 - 27 = 86 degrees
Average is the total of the numbers divided by the amount of numbers.
![\frac{27+45}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B27%2B45%7D%7B2%7D%20)
![\frac{72}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B72%7D%7B2%7D%20)
36 is the answer.
