The statement above is the same as the mathematical expression below...

x + 7 = 2x + 3

We want to solve for x in these types of problems. To do so, we must get all of the "x"s on one side of the equal sign and the constants on the other.

7 - 3 = 2x - x
4 = x

Our answer is x = 4.

So, let’s represent the number as n:
n+7=2n+3
Subtract both sides by 3:
n+4=2n
Now by n:
2n=4
Divide:
n=2
The number is 2

Callie is starting a fruit basket business the largest basket has 30 pieces of fruit but the others have 12 pieces of fruit in e
Elis [28]

Answer:

In the first basket, Callie can make 15 apples, 10 oranges and 5 bananas.


In the second basket, she can make 12 apples, 8 oranges and 4 bananas and


in the third basket, she can make 9 apples, 6 oranges and 3 bananas.

Step-by-step explanation:

The largest basket contains 30 pieces of fruit. So, it contains


1/2 of 30 = 15 apples


1/3 of 30 = 10 oranges and


1/6 of 30 = 5 bananas.


The second and third baskets should contain at least 12 pieces and at most 30 pieces (since the largest basket contains 30 pieces). Also, the number should be divided by 2, 3 and 6. So, it must be a multiple of 6.


Clearly, the number of multiples of 6 between 12 and 30 are 18 and 24.


Hence, the second basket contains 24 pieces of fruits and it contains


1/2 of 24 = 12 apples


1/3 of 24 = 8 oranges and


1/6 of 24 = 4 bananas


The third basket contains 18 pieces of fruits and it contains


1/2 of 18 = 9 apples


1/3 of 18 = 6 oranges and


1/6 of 18 = 3 bananas.

Find the midpoint of the line segment joining the points (-3,-2) and (-7,5)
Mumz [18]

Answer:

The midpoint is (-5,1.5)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2

( -3+-7)/2 = -10/2 = -5

To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2

( -2+5)/2 = 3/2 = 1.5

The midpoint is (-5,1.5)
