Answer:
Megan travelled at 9mph for 6 hours and 7mph for 3 hours
Step-by-step explanation:
Speed = distance / time
Speed*time = distance
Assuming that Megan travelled x hours at 9mph
(9*x) + (7*(9-x)) = 75
x = 6 hours
So Megan travelled at 9mph for 6 hours and 7mph for 3 hours
75000. one hundread thousand more would be 100,000 more that what is given making it 175,000
57 miles about I'm not positive but I think this is right
Answer:
4%
Step-by-step explanation:
264 interest/3 years=88 interest/year
principal x interest rate =interest/year
2200 x interest rate =88
interest rate =88/2200
interest rate =.04 or 4%
How to solve:
( x , y )
Plug the values in to the equation and solve
-3x+5y=2x+3y
(2,4) plugged in would be
-3(2)+5(4)=2(2)+3(4)
All you have to do is solve this and if the two sides are not equal(like 4=20), then it is not a solution. Just plug in (3,3) next.
Hope this helped!!!
