Solve this equation:
300+5x=450+2x
3x = 150
x = 50
so the answer is 50 books
4 hours for 18
7 hours for 25.50
Difference in hours: 7-4 = 3
Difference in cost: 25.50 - 18 = 7.50
7.50 / 3 = 2.50
A. They charge 2.50 per hour.
B. 2.50 x 4 = 10
18 - 10 = 8
The flat fee is 8 dollars
C. 8 + (2 x 2.50) = 13 dollars
Answer:
24
Step-by-step explanation:
Find the number that 9 multiplies by to get 54
so
9x6=54
do the same to four
4x6=24
Or
cross multiply
Lets put N as the missing number
4x54=9xN
Solve
216=9N
24=N

Answer:
1.5 tons
Step-by-step explanation:
First determine how much feed is eaten per day
5 * 20 lbs = 100 lbs per day
Then multiply by the number of days
30 * 100 = 3000 lbs
But the question asks tons, not lbs
We know there are 2000 lbs in a ton
3000lbs/ 2000lbs per ton = 1.5 tons
