I believe that the correct measurement in feet is 1.4 x
10^5 feet. You forgot to include the ^5.
So since that is the measurement of 1 marathon, therefore
half a marathon would simply be also half of that, that is:
0.7 x 10^5 feet
or
7 x 10^4 feet
The correct answer to your question is k=5 .
Answer:
you can subtract 2x from both sides
Then subtract 5 from both sides.
x = 2 is what the equation gives you
Step-by-step explanation:
You can do one of two things.
1. You can subtract 2x from both sides of the equation
or
2. You can subtract 5 from both sides of the equation.
Either one will give you the correct answer.
3x - 2x + 5 = 2x - 2x + 7 Combine the xs
1x + 5 = 7 Subtract 5 from both sides.
x + 5-5 = 7-5
x = 2
