1. <span>Simplify -9 + -2m to -9 - 2m
-3m = -9 - 2m
2. </span><span>Add </span>2m <span>to both sides
-3m + 2m = -9
3. </span><span>Simplify -3m + 2m to -m
-m = -9
4. </span><span>Multiply both sides by </span><span><span>−<span>1
m = 9
Done! :) our answer is m = 9</span></span></span>
Answer: The sum of the number of angles in a polygon is (n-2) * 180, where n is the number of sides, so the sum of the angles of a 17-sided polygon is (17-2) * 180 = 2700.
Step-by-step explanation:
Answer:2x+28 100% right
Step-by-step explanation:
Part A : y=$0.75m+$4.50
Part B : $8.25
Answer:
B
Step-by-step explanation:
4x + 11y = 3
11y = -4x + 3
y = -4/11x + 3/11
perp. 11/4
y - 7 = 11/4(x - 2)
y - 7 = 11/4x - 11/2
y -14/2= 11/4x - 11/2
y = 11/4x + 3/2
