Answer:
5 minutes
Step-by-step explanation:
We know that 1760 yards are in a mile. We can convert the given info into a proportion. 440/75 = 1760/x, where x is the number of seconds it takes to run a mile. Cross-multiply to get 440x = 75*1760. Divide both sides by 440 to get x = 75*4 = 300 seconds. The problem asks for how many minutes so you have to convert 300 seconds to minutes. To do this, we have to divide 300 by 60 to get 5 minutes.
Answer:
a = -8
Step-by-step explanation:
-5⁄2 a + 5 = 25
Subtract 5 from each side
-5⁄2 a + 5-5 = 25-5
-5/2 a = 20
Multiply each side by -2/5 to isolate a
-2/5 * -5/2 a = -2/5 *20
a = -8
