Answer:
it would be solved by it mom
-19x-11 should be the answer... if the 19 and x aren’t combined then the answer is x-30
First, to multiplying by a from the both sides.
au=k
Secondly, to divide by u from the both sides.
au/u as a fraction, and it equals to k/u as a fraction.
it equals a=k/u.
Answer is A. a=k/u.
Answer:
170
Step-by-step explanation:
A heptagon's internal angles add up to 900 degrees.
So:
(2x-13)+(3x-8)+(2x-3)+(2x-7)+(3x-1)+(2x+11)+(2x+9) = 900
16x - 12 = 900
16x = 912
x = 912/16
x = 57
So:
3x - 1 = 3 * 57 -1 = 170
