PLEASE HELP,, MARKING BRAINLIEST!!!<br><br> Solve for x
Trava [24]

9514 1404 393

Answer:

  x = 10

Step-by-step explanation:

The marked sides are proportional, so we have ...

  x/8 = (x +5)/12

  3x = 2(x +5) . . . . . multiply by 24 to clear fractions

  3x = 2x + 10 . . . . . eliminate parentheses

  x = 10 . . . . . . . . . . subtract 2x

_____

<em>Alternate solution</em>

We observe that the difference between the upper segment lengths is ...

  (x +5) -(x) = 5

and the difference between the lower segment lengths is ...

  12 -8 = 4

This means the upper segment lengths are 5/4 times as long as the lower segments. Then ...

  x = (5/4)(8) = 10

115. This is because there are three feet in a yard. If you divide the number of feet by three, you can find the number of yards. Therefore, 345 divided by 3 equals 115.
