Answer:

  • x = 37
  • DG = 22
  • AG = 44
  • AD = 66

Step-by-step explanation:

We presume your "centroid ratio theorem" tells you that AG = 2·DG, so ...

  (x+7) = 2(x -15)

  x + 7 = 2x - 30 . . . . eliminate parentheses

  37 = x  . . . . . . . . . . .add 30-x

Then AG = 37+7 = 44

and DG = 37-15 = 22.

Of course, AD = AG +GD = 44 +22 = 66

Which equation is an identity?
spayn [35]
7z + 10 - z = 8z - 2(z - 5)
7z + 10 - z = 8z - 2z + 10
6z + 10 = 6z + 10
6z - 6z = 10 - 10
0 = 0

Therefore, 7z + 10 - z = 8z - 2(z - 5)

How can I show my work here? I know the answer but I don't know how to show my work. please HELP ME !!!!!!!

Hey There!

In order to find the discounted price of the TV, you would have to multiply the discounted percent from the total price and subtract.

191.14 * .20= 38.23

191.14 - 38.23= 152.91

152.91 is the discounted price.

Let's determine the price after sales tax.

152.91 * 0.6= 9.17

Add 152.91 + 9.17 = 162.08

Therefore, the answer would be 162.08
