Step-by-step explanation:

the numbers : x, y

x + y = 8

x = y - 4

we use the second equation in the first :

y - 4 + y = 8

2y - 4 = 8

2y = 12

y = 6

x = y - 4 = 6 - 4 = 2

I work 20 hours week and 11.75 hour what kind of apartment will I be able to get on my income get paid every 2 weeks
daser333 [38]

Answer:

You make $270 every two weeks. Since you pay rent on the first of every month you will have made two paychecks which would equal out to $540.00 a month.. apartments usually run $700 or more a month... So sorry man, you cant afford an apartment. however, you might be able to find one that cheap, but its very very very rare. You will also not be able to afford food or any bills that will come your way..

Help me this is worth A LOT of points
andrew-mc [135]

Answer:

8.5 yards

Step-by-step explanation:

The overall triangle, as shown by the line dividing its hypotenuse in 2, can be shown as 2 right triangles whose lengths and widths are both 7.5 and 4. With this in mind we can use Pythagorean theorem or...

  • a^2+b^2=c^2

By plugging in 7.5 and 4 into <em>a </em>and <em>b </em>respectively, we get the equation:

  • (7.5)^2 + (4)^2 = c^2

Now we can square 7.5 and 4, add them together and then square root the resultant to get our final answer.

  • 56.25 + 16 = x^2
  • 72.25 = x^2
  • √72.25 = x
  • x = ±8.5

The length of a triangle cannot be negative so disregard the possible negative value for 8.5.

  • x = 8.5
