The expression representing the amount Melanie earns each hour from babysitting, based on the expression $4x + $16 and her working for four hours, is represented by the variable $x. To determine the hourly rate, we would divide the total hourly charge by the number of hours, but the specific value of $x is not given.

The given expression representing Melanie's total earnings from babysitting for four hours is $4x + $16. Here, $16 is the upfront charge and $4x represents the additional hourly charge multiplied by the number of hours worked. To find the expression representing the amount she earns each hour, we look at the variable part of the expression, which is $4x.

Since Melanie worked for four hours, this part of the expression ($4x) must account for her earnings per hour times the number of hours worked. To find her earnings per hour, we divide the total hourly charge by the number of hours. Therefore, the expression for the hourly rate is $x.

To determine the specific amount that x represents, we would need additional information, such as the total amount she earned after working the four hours. However, based on the given expression, we can conclude that x is representative of Melanie's earnings per hour.

Answer: 10 feet

Step-by-step explanation:

Let h be the height of lamppost.

Since both the person and the lamppost are standing vertical to the ground,  making similar right triangles.

Because the two triangles are similar, the ratio of their sides is the same.

Therefore, we have

[tex]\frac{\text{height of lamppost}}{\text{distance of lampost from mirror}}=\frac{\text{height of person}}{\text{distance of person from mirror}}\\\\\Rightarrow\frac{h}{6}=\frac{5}{3}\\\\\Rightarrow\ h=\frac{6\times5}{3}\\\\\Rightarrow\ h=10[/tex]

Hence, the height of the lamppost = 10 feet.

Setting up a proportional relationship between mirror and lamppost, the height of the lamppost is 10 feets.

Setting up a proportional relationship :

[tex]\frac{Hp}{Dp} = \frac{Hl}{Dm} [/tex]

[tex]\frac{5}{3} = \frac{Hl}{6} [/tex]

Cross multiply :

Hl × 3 = 6 × 5

3Hl = 30

Hl = (30 ÷ 3)

Hl = 10

Therefore, the height of the lamppost is 10 feets.

Mr. Hall's car traveled approximately 17.23 miles per gallon of gasoline when he drove a total of 37.9 miles using 2.2 gallons.

To calculate the number of miles Mr. Hall's car traveled per gallon of gasoline, we need to divide the total miles driven by the total gallons of gasoline used. Mr. Hall drove a total of 37.9 miles and used 2.2 gallons of gasoline. Thus, to find the miles per gallon (MPG), the calculation would be:

MPG = Total Miles Driven / Total Gallons of Gasoline Used

MPG = 37.9 miles / 2.2 gallons

MPG = 17.23 miles per gallon

So, for each gallon of gasoline, Mr. Hall's car traveled approximately 17.23 miles.

The mystery number is really 32.

An equation represents equality of two or more mathematical expression.

Solutions to an equation are those values of the variables involved in that equation for which the equation is true.

The mystery number = M

The sum of the number and 8 = M + 8

Half of that sum =  (1/2)(M + 8)

10 added to that sum = (1/2)(M + 8) + 10

Thus (1/2) (M + 8)  + 10  =  30

Now, subtract 10 from each side:              

(1/2) (M + 8)  =  20

Multiply each side by  2 :        

M + 8   =  40  

Subtract 8 from each side:                                

M  =  32 .
