M + 5n = 7
subtract 5n from each side
m = -5n + 7
If you're looking for c, then the answer is 6 in. I found this answer by using a2+b2=c2 So 4 squared + 5 squared = 41. So then i found the square root of 41 which is 6.40, which rounds to 6.
B= 60
To find b you must do the pythagorean theorem because it is a right triangle
65^2 - 25^2=b^2
3600=b^2
60=b
x= 18
To find x you must know that a triangle is made up of 180 degrees.
x= 180-(72+90)
x=180-162
x=18
hope this helped :)
It is -12, negative + negative is Negative unless if its with a positive it will cancel out
ex, -12 + 6= -6
14. t=d/r
15. m=e/c^2
16. c=-p+r
