Angl G = angle I because of alternate interior angle theorem
the triangle JHG is congruent to the triangel JFI because the corresponding angles F and J equal with J and H in the other triangle and the sides between them are equal FJ and HJ
therefor GJ = IJ because of the congruence

Josh had $10 more than Carly, so he gave Carly half of his money. Then Carly had more money than josh, so she gave Josh $4. Then

DedPeter [7]

each person starts with $8.

<u>Step-by-step explanation:</u>

Here we have , Josh had $10 more than Carly, so he gave Carly half of his money. Then Carly had more money than josh, so she gave Josh $4. Then they both had $13. We need to find How much money did each person start . Let's find out:

Suppose Carly had $x , Josh had $10 more than Carly i.e. $(x+10), so he gave Carly half of his money i.e.

⇒ $\frac{x+10}{2}$ ,Now , Josh have $ $\frac{x+10}{2}$ & Carly have $x + \frac{x+10}{2}$ .

Then Carly had more money than josh, so she gave Josh $4 . So ,

Josh now have $ $(4+\frac{x+10}{2})$ and Carly now have $ $(x+\frac{x+10}{2} -4)$ . Since both are equal :

⇒ $(x+\frac{x+10}{2} -4) = (4+\frac{x+10}{2})$

⇒ $x-4 = 4$

⇒ $x=8$

Therefore , each person starts with $8.

So you would do 100 divided by 12.5 and that equals 8. So the answer would be 8mph

How do I solve 20? Thanks

Gnom [1K]

20)

using
<span>a^3 + b^3 = (a+b)(a^2 − ab + b^2)
</span>so
w^3 + 125z^3
= w^3 +(5z)^3
= (w + 5z)(w^2 - 5wz + 25z^2)

hope it helps
