Answer:
A
Step-by-step explanation:
In this problem, first u would have to keep the base of 3, then multiply the two powers together to get -28.
However, u can't leave a negative power in the numerator, so u bring the base and the power down into the denominator, change the sign of the power to make it positive, and put a 1 in the numerator.
Answer:
1.25 gal
Step-by-step explanation:
5/4 = 1.25
It has no solution because x is always the same amount. So.. for example.
lets say x = 10.
then it would be 10 + 2 = 10 + 3.
12 doesnt = 13. :)
The angles inside a triangle add up to 180°
The 3rd angle is supplementary to (6x+1)°
Supplementary means they make a straight line (i.e 180°)
1st angle = 79°
2nd angle = (2x+10)°
3rd angle = 180° - (6x+1)°
180 = 79 + (2x+10) + 180 - (6x+1)
180 = 79 + 2x + 10 + 180 - 6x - 1
combine like terms
180 - 180 - 79 - 10 + 1 = 2x - 6x
-88 = -4x
-88/-4 = x
22 = x
