(2*40%+x*10<span>0%)/(2+x) = 70%; calculate x !</span>
Answer: B
Step-by-step explanation:
100 feet every 2 minutes
100 divided by 2 is 50
50 ft per minute
B is the answer
The equation of a line is defined by: y=mx+b
Step 1: Find the slope (rise over run) so, the rise is 15.7 and the run is 6. 15.7/6=2.62
y=2.62x+b
Step 2: Find the b value (y intercept) - this is where the line goes through the y axis. In this case, it's 15.7
Step 3: add the slope and the b value together - y=2.62x+15.7
Add all sides together to find the length of each side
Go over the x axis up 5 and over the y axis left 1
