2.99+2.99+.79+.79+.79=$8.35

Hope this helps :D

Your final $8.35

Step-by-step explanation:

The best way to approach this would be to create an equation. You can do this either way by adding it up:

$2.99+$2.99+$0.79+$0.79+$0.79=$8.35

OR

You can set up an equation based on the question. Assuming are person is about to buy TWO magazines at the price of $2.99, We can Write it as:

2($2.99)

Then, We will be buying three packs of gum at $0.79. We can combine the equation to look like:

2($2.99)+3($0.79)= $8.35

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
