Answer:
Y=15-5/6x
Step-by-step explanation:
Ax+By=C
A=5,
B=6,
C=90,
So, put in the numbers to variables:
5x+6y=90.
6y=90-5x
y=15-5/6x
So you have to just subtract, 65-53=12 that didn't bring sleeping bags
Ur answer is c hope this helps
Hey <span>kirinaallison, thanks for submitting your question to Brainly!
The answer is </span>


+5x - 2x - 10
x(x+5) - 2 (x+5) - 2(x+5)
(x + 5) (x-2)
Hope my answer was well explained if you have any more questions reply to my answer. :)
First one.
Since the two angles are congruent through vertical angles theorem,
5x = 6x - 8
5x - 6x = -8
-x = -8
x = 8
Second one.
Use the 180° rule.
(8x - 2) + (2x + 2) = 180
8x - 2 + 2x + 2 = 180
8x + 2x + 2 - 2 = 180
10x = 180
x = 180 / 10
x = 18
Third one.
Vertical angle theorem.
7x = 5x + 40
7x - 5x = 40
2x = 40
x = 40 / 2
x = 20
