Answer:
100 miles in 20 minutes.
Step-by-step explanation:
300/60 = x/20
x = 300/60 * 20
x = 100
Answer: Ann = 67 Josh = 60 Claire = 30
Step-by-step explanation: You get the equation 5x+7 = 157. You get the equation because for example, Claire = x then josh = 2x and Ann = 2x + 7. You do all the math and boom! You get the answer :)
So slope=rise/run
rise=8
run=12
8/12=4/6=2/3
the slope=2/3
