Total distance: d = 3 km
Minutes run: x
Distance run = (1 km / 2 minutes) * x = (1/2)x
Distance from the finish line = total distance - ditance run = 3 - (1/2)x =
= - (1/2)x + 3
Answer - (1/2)x + 3
Answer:
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Remember to do the opposite of PEMDAS.
PEMDAS =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, subtract 6 from both sides:
2x + 6 (-6) = -r - 15 (-6)
2x = -r + (-15 - 6)
2x = -r + (-21)
2x = - r - 21
Next, divide 2 from both sides:

Answer:
I wasn't sure if you meant centimeters, inches or degrees. But since I don't know, I'll answer all three.
Step-by-step explanation:
Centimeters- Possible
Inches- Possible (Extremely big. I suggest using a big whiteboard to draw out)
Degrees- Impossible (All degrees in a triangle have to add up to 180)
