You did everything right. You leave "t" by itself because you don't have a given time frame. But I'll say you used the correct formula and showed your work well.
I hope this helps you
M^2+R^2=W^2
M^2+16=25
M^2=9
Step-by-step explanation:
You can put the value of x into the equation to solve for y. Hopes this works.
When two lines intersect to form a 90 degree angle, these lines are called perpendicular lines.
1). 2x-1>0
2x>1
x>½
2) 21-3y<0
-3y<-21
y>7
3) 5-3c>80
-3c>75
c<-25
