Answer:

$6.35

Step-by-step explanation:

Number of pennies = 10% of the 50 coins = .10(50) = 5

Number of dimes = 34% of the 50 coins = .34(50) = 17

Number of nickels = 7 + no. of pennies = 7 + 5 = 12

Number of quarters = 50 - 5 - 17 - 12 = 16

Each penny is 1 cent, each nickel is 5 cents, each dime is 10 cents, and each quarter is 25 cents.

Amount of money in the bag = 5(1) + 17(10) + 12(5) + 16(25) = 5 + 170 + 60 + 400 = 635 cents = $6.35

According to the solving the correct expression of the given data is:

S = 5T/(T - 5).

<h3>What does a math expression mean?</h3>

At least two numbers as well as variables, one or more arithmetic operations, and a statement are all required components of a mathematical expression. With the help of this mathematical operation, you can multiply, divide, add, or subtract. A sentence has the following structure: (Number or Variable, Math Operator, Number or Variable) is an expression.

<h3>How does a term come to mind?</h3>

The evaluation of each algebraic expression requires the substitution of one integer for each variable and the execution of the arithmetic operations. The variable x in the preceding example has the value of 6 since 6 plus 6 = 12. Our variables' values can be substituted for the original variables if we are aware of them, allowing us to evaluate the expression with those values instead of the original ones.

<h3>According to the given information:</h3>

Let S be the number of hours it would take Sharon to paint the shed alone.

Kelly alone can paint the shed in T hours,

so she can paint (1/T) of a shed per hour.

Sharon alone can paint (1/S) shed per hour, so, working together.

They can Paint:

(1/T)+(1/S)

it takes them five hours to paint the shed together, they can paint (1/5) shed per hour.

$\frac{1}{S}+\frac{1}{T}=\frac{1}{5}$\\

$\frac{1}{S}+\frac{1}{T}-\frac{1}{T}\\\\=\frac{1}{5}-\frac{1}{T}$

After simplifying this we get:

(T - 5)/5T

the reciprocal of both expressions:

S = 5T/(T - 5)

According to the solving the correct expression of the given data is:

S = 5T/(T - 5).
