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
A right angle measure 90°, so like the angle would look like: L, the corner of the L
Answer:
Lindsay owns 12 books
Step-by-step explanation:
1/3x:Lindsay
x:Destiny
1/4x: Henry
1/3x+1/4x+x=57
4/12x+3/12x+x=57
7/12x+x=57
19/12x=57
x=57*12/19
x=36
1/3x=36/3
1/3x=12
