You go to the market to buy fruit. two apples and one banana cost $5. if you buy two apples and three bananas the cost is$7.how much does each apple and each banana cost?

An apple costs $2 and a banana costs $1.

Step-by-step explanation:

x = cost of 1 apple and y = cost of 1 banana. So:-

2x + y = 5

2x + 3y = 7

Subtract the first equation from the second. We get:-

2y = 2

y = 1

and since 2x + y = 5,  2 x + 1 = 5 and

x = $2.

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to
