For question A, the answer is 2. Since the sale sweatshirt if 40% LESS, this means that 60% of the original price still remains. 28.80 x .60 = 17.28
For question B, the answer if 4. You can divide 17 by 20 getting .85
(-14w) - (-3) - (-5w) equals
-9w + 3
or if what you're saying is
-14w - 3 - 5w it equals
-19w - 3
or if what youre saying is
(-14w - 3) - 5w it equals
-19w - 3
No because when you add any 2 sides the answer has to be bigger than the 3rd side
ex: 2+7=9
9 is too small, so the tips of the side that is 2ft would not touch the side that is 7ft
Answer:
x = 13
Step-by-step explanation:
Sum or interior angles of a triangle is 180,
6x + 19 + 5x - 15 + 3x - 6 = 180
6x + 5x + 3x + 19 - 15 - 6 = 180
14x + 19 - 21 = 180
14x - 2 = 180
14x = 180 + 2
14x = 182
x = 182 / 14
x = 13
→ 
8 and 10 can both be divided by 2. So, 8 ÷ 2 is 4 and 10 ÷ 2 is 5.
Hope this helps :)
