Answer:
a = 11
Step-by-step explanation:
One is given the following equation:
3a - 7 = 26
Use inverse operations to solve this equation:
3a - 7 = 26
(add (7) to both sides)
3a = 26 + 7
Simplify,
3a = 26 + 7
3a = 33
Inverse operations,
3a = 33
(divide both sides by (3))
a = 33 / 3
Simplify,
a = 11
Answer:
R(p) = -6p^2 + 60p....
Step-by-step explanation:
Revenue, R = quantity sold * price
Price = p
Quantity sold = q = -6p + 60
R(p) = q*p
where q=-6p + 60
= (-6p + 60) * p = -6p^2 + 60p
Answer: R(p) = -6p^2 + 60p....
It should be 12.57 i remember having that question a few months back and i got it right
All you need to do is convert all equations into standard form by using the distributive property on each equation.
Since each min is 60 seconds you multiply 60 by the number of minutes which is 7 and you get 420:
60x7=420 Then you add 30 seconds equaling 450 seconds total
Then you divide 450 by 4 since she ran 4 laps.
So, Stephanie ran 112.5 seconds per lap
