Answer:
See like terms have the same variables
E.g 2x+4y-x+7y
We should take the same variable together with the same signs so here
2x-x will be 1x
4y+7y will be 11 y
So x+11y
Hope it helps!
Answer:
The angle is 52 degree.
Step-by-step explanation:
length of of side, L = 8
Hypotenuse, H = 13
According to the trigonometry,

<span>(x – 8)² + (y – 9)² = 3
(x – 8)² + (y – 9)² = 14
</span>are the correct answers
Answer:
There were 261 Cheeseburgers and 87 Hamburgers sold on Tuesday
Step-by-step explanation:
Lets write some equations where H=Hamburgers and C=Cheeseburgers:
1) H+C=348
2) C=3H
1) Substitute 3H as C in the first equation:
3H+H=348
2) Combine alike terms:
4H=348
3) Divide both sides by 4:
H=87
4) Now, substitute 87 as H in the first equation:
87+C=348
5) Subtract 87 from both sides:
C=261
