You just cross multiply and then simplify
Answer:
16x- 20y=20
Step-by-step explanation:
20y-20y =0
so answer is 16x

If Ava has 34 candy bars, and each box can hold 5 bars, then we need to find out how many boxes that are filled up.

Divide the number of candy bars (34), by the number each box can hold (5)

Since we cannot have 6.8 boxes, we have to round down to 6.


To check our answer, we multiply the number of boxes (6), by the number of bars in each box (5), to get 30. We add Ava's extra bars (4), and we get the number we started off with: 34. This proves our answer is correct!
I believe it is 3x+21 but i could be wrong :/ my explaination is -3 • -X would be +3x because it was distributed and -3 • -7 would be +21
The base angles of an isosceles triangle are equal
The base angles are 15 degrees, while the vertex angle is 150 degrees
The base angles are given as:
Base = (6a- 3) and (a + 12)
So, we have:

Collect like terms


Divide both sides by 5

Substitute 3 for a in Base = (6a- 3),



So, the base angle is 15 degrees.
The vertex angle is calculated using:

So, we have:


Hence, the vertex angle is 150 degrees
