Answer:
The answer is (A) (-6,4).
Step-by-step explanation:
First you have to multiply the first equation by 6 and the second equation by 4. Then next you subtract the second equation from 1.
30x + 24y = - 84
12x + 24y = 24
18x + 0. = - 108
=> 18x = - 108
=> x = - 108 / 18
=> x = - 6
Then for the next step
then put in x = - 6 in equation 2 and solve for y
(
3x + 6y = 6)
(3×(-6) + 6y = 6)
( - 18 + 6y = 6)
( 6y = 18 + 6
)
( 6y = 24)
(y = 4
)

When a skateboarder starts from rest and moves down a hill with constant acceleration in a straight line for 6 seconds in a second trial he starts from rest and moves along the same straight line with the same acceleration for only 2 seconds. His displacement from his starting point compared with the first trial is one-ninth as large. This will make the answer choice C.
The answer would be D because she owes $300 and each month she pays off $25
13/50
26/100, reduce it
2 can go into both 26 and 100 evenly
26/2 = 13
100/2= 50
It cant be reduced anymore
If you need me to explain more I can just lmk :)
Answer:
180-65 = 115
Step-by-step explanation:
it is 115 since <7 <6 are a linear pair so they make a 180 angle so 180-65 is 115
