Answer:
m = 170
Step-by-step explanation:
The angles are supplementary so they add to 180 degrees
70 + m-60 = 180
Combine like terms
10 + m = 180
Subtract 10 from each side
10-10 +m = 180-10
m = 170
Comparing the temperature of a coolant before and after use in a machining process.
Step-by-step explanation:
The temperature of a coolant in the polar region was found to be modeled by the equation t=(8x-55)° where t is the final fluid temperature after being used for cooling ,x is the time the fluid is applied on the cutting edge and -55 is the normal temperature of the fluids used for cooling processes in a machine garage.

5x+2y=9
Move variable to the right side and change
It’s side.
5x=9-2y
Divide both sides of the equation by 5
X = 9/5 - 2/5y
Final solution
Answer: x = 9/5 - 2/5y
Answer:
x = (c+a)/2
y = (c-a)/2
Step-by-step explanation:
Add the two equations and you get ...
(x +y) +(x -y) = (c) +(a)
2x = c+a
x = (c+a)/2
--
Subtract the second equation from the first and you get ...
(x +y) -(x -y) = (c) -(a)
2y = c-a
y = (c-a)/2

Comment on this problem
This is what I call a "sum and difference" problem. The solution shown here is (obviously) the generic solution to such a problem. Remembering this can get you quickly to the answer any time you're given the sum of two unknowns and their difference.
