  • Addition Property of Equality

Functions

  • Function Notation

Systems of Linear Equations

  • Solving methods: Substitution/Elimination

Step-by-step explanation:

Step 1: Define

Identify given.

[Ralph's Walking Distance Function]: d = -6t + 10

[Joan's Bicycle Distance Function]: d = 14t

Step 2: Find Meeting Point

To find where Joan and Ralph will meet, we need to find where they intersect. Therefore, we need to find the time which they both meet up at. To do this, we can use the process of substitution to find our value of t:

  1. [Equation 1] Substitute in d:
    \displaystyle\begin{aligned}d = -6t + 10 & \rightarrow 14t = -6t + 10\end{aligned}

From here, we can simply use techniques listed under "Algebra I" to solve for t:

\displaystyle\begin{aligned}14t & = -6t + 10 \n20t & = 10 \nt & = \boxed{ (1)/(2) } \n\end{aligned}

∴ both Joan and Ralph will meet up in half an hour, or 0.5 hours.

Step 3: Find Mileage

To find how many miles they will meet up at, we substitute the number of hours elapsed (found in Step 2) and substitute it into any of the equations given:

\displaystyle\begin{aligned}d & = 14t \n& = 14 \bigg( (1)/(2) \bigg) \n& = \boxed{7} \n\end{aligned}

∴ Joan will meet Ralph after 7 miles.

A bathroom is 6 ft 5in long and 4 ft 3in wide what is the area of the bathroom in square feet. I need work with the answer

Answers

you just multiply the sides. 
Firstly, it's easier if you convert both measurements to inches.
so you'd do 6 x 12 = 72 , 72 + 5 = 77 inches
and 4 x 12 = 48 , 48 + 3 = 51 inches.

Then you multiply the sides, so:
77 x 51 = 3927 inches
then you divide by 12 to get how many feet and inches it is
3927/12 = 327 feet and 4 inches
