There are 14 times in the table.  Add up all 14 times, and divide the sum by 14.  The result is the "mean 100-meter sprint time," assuming that you've rounded this off to the nearest tenth of a second.

What is the value of a in the equation 5a -10b = 45 when b = 3
leva [86]
Salutations!

5a-10b = 45

value of b = 3

Multiply 10 and 3

10*3=30

Now, you can solve the equation --

5a-30=45

separate the variables aside, and the numbers aside.

5a=45 +30

5a=75

a=75/5

a=15

Hope I helped (:

Have a great day!
