The octagon has a total interior measure of 1080 degrees. Good luck, hope this helped!

First, you would do 1080 / 180, because 180 is the sum of the angles in a triangle. Then, you would get the answer of 6. Since the triangles on the left and right of a shape is left out, you would do 6 + 2 = 8. Ask yourself: Which polygon has 8 sides: An octagon!!!

Lance wrote down a lot of plus sevens and minus fours. Altogether he wrote 22 digits. When he came to add them all up the total

AURORKA [14]

So, when solving this: you’ll want to consider multiples of 7 and 4.

7,14,21,28
4,8,12,16,20,24,28

If you write four +7’s and seven -4’s, they cancel out. Given that that is 11 digits, do it twice and you have your answer.

Eight +7’s
Fourteen -4’s

Solve the system of equations below. Enter your answer in the boxes.

Simplifying
8a + 12b = 92

Solving
8a + 12b = 92

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-12b' to each side of the equation.
8a + 12b + -12b = 92 + -12b

Combine like terms: 12b + -12b = 0
8a + 0 = 92 + -12b
8a = 92 + -12b

Divide each side by '8'.
a = 11.5 + -1.5b

Simplifying
a = 11.5 + -1.5b
