Answer:
Step-by-step explanation:
Find the total ° of the shape.
(5-2) x 180°= 540°
x+21°+x = 540°-105°-154°-88°
2x+21° = 193°
2x = 193°-21°
2x = 172°
x = 172° ÷ 2
x = 86°
Answer:
True
Step-by-step explanation:
The pages left = total pages - the pages read
(10b + 3) - (-2b +78)
10b + 2b + 3 - 78
12b - 75
The pages left is equal to 12b - 75
Answer:
(11, ∞).
Step-by-step explanation:
3 (x+2)+9<6(x-3)
3x + 6 + 9 < 6x - 18
-3x < -18 - 6 - 9
-3x < -33
x > 11 (Note the inequality flips as we are dividing by a negative value).
