Answer:
m = 2
n = -4
Step-by-step explanation:
Using elimination method:
4m + n = 4
m - n = 6
--------------------
5m = 10 // n-n = 0, solve for me
m = 10/5 //divide both sides by 5
m = 2
Pick any only of the equation, replace me with it's value.
m - n = 6
2 - n = 6 //subtract 2 on both sides
-n = 6-2
-n = 4 //Change sign, multiply by -1
n = -4
Solution:
m = 2
n = -4

Answer:
(3, 12)
Step-by-step explanation:
x + y = 15
x - y = -9
add them together
2x + 0y = 6
2x = 6
x = 6/2
x = 3
substitute 3 into any equation, i chose x + y = 15
3 + y = 15
y = 12
check for 2nd equation:
3 - 12 = -9
-9 = -9
Answer:
200
Step-by-step explanation:
90-35=125
180-125=55
55x4=220
220= 200
It is a scalene obtuse angle because it is greater then 90 degrees and none of the side lengths are equal.
