First, you solve for m by adding the equations.
m+n=100
+ m-n=30
--------------
2m=130
m=65
Now plug in 65 for m into one of the original equations
65+n=100
n=35
You can double check by plugging them both in:
65+35=100 and 65-35=30
Hope that helps.
Answer:
Divide 1200 by 1100, whatever you get from that turn it into a percentage. You may have to simplify.

Answer:
The value of x is - 11
Step-by-step explanation:
Given as :
∠ M = (5x +90) °
∠ R = 55°
The sum of measure of angle M and R are complementary
Complementary Angle are those when sum of two angle equal to 90°
∵ Angle M and R are complementary in nature
∴ ∠ M + ∠ R = 90°
Or, (5x +90) ° + 55° = 90°
Or, 5x = 90° - 90° - 55°
Or, 5x = - 55°
∴ x = - = - 11
Hence the value of x is - 11 Answer
69.1 do the maths my manzzz
Answer:
Radius = 5.75
Circumference = 36.13
Step-by-step explanation:
Here we have the diameter, and the radius is half of the so 5.75. For the circumference, we can use the formula C=2πr
