Step-by-step explanation:

Each vertex has a single-letter label.

Each edge joins two vertices, and is named by naming those two vertices.

The base is the polygon opposite the point where all of the triangles come together.

Your hourly salary increased from $15 to $22 what is the precent increase in your salary?

Elanso [62]

The percentage increase is 46%.

Original number/start = $15

End number = $22

Increase = $22 - $15 = $7

% increase = Increase ÷ Original Number × 100

Substitute in known values

% increase = 7 ÷ 15 × 100

Divide

% increase = 0.46 × 100

Multiply

% increase = 46%

The percentage increase is 46%.

Solve this question a=7+3

mr Goodwill [35]

Answer:

Step-by-step explanation:

The answer is 10 because 7 + 3 equals 10!

This can be proven by adding 7 + 3 or by subtracting in a certain way.

7 + 3 = ?

7 + 1 = 8

7 + 2 = 9

7 + 3 = 10

You can show more work by subtracting your answer or 10 in this case, which means that you subtract 7 by 10 or 3 by 10, either way is ok.

If you subtract 7 by 10, ( 10 - 7 ) then you get 3

If you subtract 3 by 10, ( 10 - 3 ) then you get 7

If the number you subtracted matches the number that you didn't subtract, then your answer is correct.

Hope this helps! <3
