Answer:
y = -51
Step-by-step explanation:
y - (-10) = -41
Subtracting a negative number: - (-10) is the same as just adding a positive number + 10, so we'll use this to simplify the expression.
y + 10 = -41
Now, we can subtract 10 from both sides of the equation in order to isolate y.
10 - 10 = 0
-41 - 10 = -51
This means the equation is now:
y = -51
Let's check this answer:
Input -51 as y:
-51 - (-10) = -41
-41 = -41
It works!
This means y = -51 is the answer!
Answer:
12.5 miles per hour.
Step-by-step explanation:
There are 60 minutes in 1 hour so:
12 minutes = 12/60 = 1/5 of an hour.

= distance in miles / time in hours
= 2.5 / 1/5
= 2.5 * 5
= 12.5 miles per hour.
