If p is the price of a bag of popcorn and d is the price of a drink
2p + 3d = 18.25 Mohamed’s order
4p + 2d = 27.50 Miguel’s order
If we double the first equation
4p + 6d = 36.50
Now subtract the second equation (find the difference between them)
4d = 9.00
d = 2.25
Substitute in the first equation
2p + 3 x 2.25 = 18.25
2p = 18.25 - 6.75 = 11.50
p = 11.50 / 2 = 5.75
Popcorn was $5.75 a bag and drinks were $2.25 each
The rate in miles per hour is: 7.5
First you would multiply 60 by 60 because there is 60 minutes in an hour and 60 seconds in a minute. Then you would multiply by 11 then divide by 5280 because there’s 5280 feet in a mile
In 3 hours they would travel: 22.5 miles
You would multiply 7.5 times 3
Set the function equal to 0 and solve for
x= 3,2 + i, 2 −i
Answer:
perimeter =
Step-by-step explanation:
perimeter
- = 2 × pi × radius
- = diameter × pie ( 2 × radius )
- = 23 × pi
=
