your car broke down and the final bill was $306.50. The part that was replaced cost $119 and the charge mechanics labor was 75 p
erastova [34]

Answer:

\huge\boxed\text{Equation:}\huge\boxed{\text{Equation:   }119+75x=306.50}\\

\huge\boxed{\text{Hours worked on:   } 2.5}

Step-by-step explanation:

We can create an equation for this problem by converting the words to an equation.

The <em>flat fee</em> was $119. We then add $75 for every hour worked. This means that this becomes 119+75x. Since the total cost was $306.50, the equation is 119+75x=306.50.

We can now solve for x, the amount of hours worked, to find it’s value.

119 + 75x = 306.5\\\\75x=187.5\\\\x = 2.5

Hope this helped!

Let a represent a non zero rational number and let b represent an irrational number. Which expression could represent a rational
Marta_Voda [28]

The operation between a rational and a irrational number that results in a rational number is a multiplication, hence the expression ab could represent a rational number.

<h3>What are rational and irrational numbers?</h3>

If a number can be represented by a fraction, it is rational, otherwise, it is irrational.

The addition/subtraction of a rational and an irrational numbers is irrational, while the multiplication is rational, hence the expression ab could represent a rational number.

If f:X is 3x + b and ff(2) = 12, find the value of b​
Tamiku [17]

Answer:

b =6

Step-by-step explanation:

Given

f(x) =3x + b

f(2) = 12

Required

Find b

f(2) = 12 implies that:

12 = 3 * 2 + b

12 = 6 + b

Collect like terms

b = 12 - 6

b =6
