Answer:
r=−1/5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(r−10)=−51
(5)(r)+(5)(−10)=−51(Distribute)
5r+−50=−51
5r−50=−51
Step 2: Add 50 to both sides.
5r−50+50=−51+50
5r=−1Step 3: Divide both sides by 5.
5r/5=−1/5
r=−1/5
I think it's either 18 or 24.. I've had this question before but I'm not positive which answer I put and if it was correct, sorry I couldnt help much :(
Answer:
8/mile = 8
Step-by-step explanation:
convert hours to minutes. 3 hours, 28 minutes converted to minutes is...

208/26 (divide time by distance ran)
=8 (8 minutes per mile)

Answer:
3
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( 3 - -3)/( 7-5)
= (3+3)/(7-5)
= 6/2
= 3
