Answer:

x+ (2x+3) +(x+2)=45

Step-by-step explanation:

First number is x

So using this ,second number which is three more than twice of the first can be written as 2x+3

Now , The third number is two more than the first so it is x+2

Sum of the three numbers can be written as

x+ (2x+3) +(x+2)

In the question it is given that the sum is 45 so we can equate the equation in x to the given sum to solve it for x .

Hence

x+ (2x+3) +(x+2) =45

1. Three apples, a, and two peaches, p, sell for $1.25.
Simora [160]

Answer:

$0.25

Step-by-step explanation:

You can use systems of equations to solve this.

3a+2p = 1.25

5a+p = 1.5

Multiply the second equation by 2.

3a+2p = 1.25

10a+2p = 3

Subtract the bottom from the top

-7a= -1.75

Divide by -7

a= 0.25

Each apple is $0.25 (in this case, the peach also costs $0.25)
