I'll use 24 as an example.
12.5=0.8x
In order to solve this, you have to get the x by itself. See how the x is being multiplied by 0.8? Well, in order to get rid of the 0.8, you have to the opposite thing: divide 0.8x by 0.8. Since 0.8 / 0.8 is 1, that gets the x by itself. BUT,in order to keep the equation right, you have to do the same thing to both sides of the equation. So, you divide 12.5 by 0.8 too, and you get x=15.625.

If you actually need the answers to all of them ( like for checking ) say so in my inbox.

Find the length of the missing side. The triangle is not drawn to scale.

suter [353]

Answer:

D.) 8

Step-by-step explanation:

You can use the Pythagorean theorem because this is a right triangle:

$a^2+b^2=c^2$

a and b are the legs and c is the hypotenuse. The hypotenuse is always the longest side in a right triangle (since it is opposite the biggest angle). The two legs squared have to add up to the hypotenuse squared.

Fill in values:

$a^2+15^2=17^2$
