Answer:
Charles practiced for the relay race for D. 9 hours last week.
Step-by-step explanation:
First, I would find the ratios the ratios for converting hurdle to javelin and javelin to relay.
Hurdle : Javelin ; 5 : 1.5
Javelin : Relay ; 2.5 : 5 or 1 : 2
Next, find the factors compared to the original numbers for hurdle to javelin.
15 / 5 = 3
To find the amount of javelin time they did, multiply 1.5 by the factor we got, 3.
1.5 * 3 = 4.5
Finally, double 4.5, since Charles does twice as much relay than he does javelin.
4.5 * 2 = 9 hours
Example A: a/2
A fraction shows division as well! I’m not sure about the rest though....
Answer/Step-by-step explanation:
✍️Slope of the line using two points, (2, 2) and (6, 10),

✍️To find the equation of the line in slope-intercept form, we need to find the y-intercept (b).
Substitute x = 2, y = 2, and m = 2 in y = mx + b, and solve for b.
2 = (2)(2) + b
2 = 4 + b
2 - 4 = b
-2 = b
b = -2
Substitute m = 2 and b = -2 in y = mx + b.
✅The equation would be:


✍️To find the value of a, plug in (a, 8) as (x, y) into the equation of the line.


Add 2 to both sides


Divide both sides by 2


a = 5
✍️To find the value of b, plug in (4, b) as (x, y) into the equation of the line.



He walks 7,300 miles in 1 year
Is it multiple choice? If not I would say 215=5(x)-29
