Similar triangles so AC:BC=AE:DE
15+6=21 = AE
15:12.5=21:?
to get from 15 to 12.5 you divide by 15 and times by 12.5 so do this the to the other side
21/15=1.4
1.4 x 12.5=17.5
So DE=17.5
Answer: x+6>84
6 greater than x ---> x+6
greater than 84-------> >84
Hopefully this helped!
85 is not a prime, it’s a composite number.
This equation<span> has x terms on both the left and the right. To solve an </span>equation<span> like this, you must first get the variables on the same side of the </span>equal<span> sign. You can subtract 5x on each side of the </span>equal<span> sign, which gives a new </span>equation<span>: x + </span>5<span> = 10. hope this helps</span>
