Christopher went into a restaurant and bought 5 hamburgers and 10 drinks, costing a total of $52.50. Wyatt went into the same restaurant and bought 2 hamburgers and 9 drinks, costing a total of $31. Write a system of equations that could be used to determine the price of each hamburger and the price of each drink. Define the variables that you use to write the system.

Step-by-step explanation:

Let the price of each hamburger be a and the price of drink each be b.

5a+10b=52.50

2a+9b=31

5a+10b=52.50

a=10.5-b

2(10.5-b)+9b=31

7b=10.5

b=1.5

a=10.5-1.5

a.9

∴The price of each hamburger is $9 and the price of each drink is $1.5

the answer is 3,600,000 cubic centimeters

step-by-step explanation:

first you have to convert all the units into centimeters

2 meters = 200 centimeters

1.5 meters = 150 centimeters

to find the volume of a rectangular prism you multiply all the sides

120 * 200 * 150 = 3,600,000

the answer is 3,600,000 cubic centimeters

hope this !
