Answer:

y=29

Step-by-step explanation:

Since the angles are across a vertex from one another, they are congruent and equal. You can also see this by reflecting or folding it in half through the vertex. They will be the same. This means we can write the following equation and solve using inverse operations:

4y-8=79+y

4y-y-8=79+y-y

3y-8=79

3y-8+8=79+8

3y=87

y=29

what is -8x-9=-21, can someone work out the problem and show me what they did to get there answer so i can understand it?

SashulF [63]

- 8x - 9 = - 21

Add 9 to both sides:

- 8x = - 12

Divide both sides by - 8:

x = -12/-8

x = -3/-2

x = 3/2 OR 1.5

Hope this answer helps :)

5. photo album: $25.50, 10% markup

sasho [114]

Answer:

$28.05

Step-by-step explanation:

If you want to find how much the photo album is after the markup, you first have to find 10% of the original price. 10% of $25.50 is $2.55, so you add $2.55 and $25.50 to find the price after the markup.

Hope this helps!
