Explanation:
Since we have given that
Speed at which Eugene walked all the way to school = 3 mph
After realizing that she forgot her math book, she ran back
Speed at which Eugene walked back to her house = 7 mph
Let the distance between her house and her school be x
According to question,

Hence,

X = 0, for starters. Also, X + Y = Y( true for any Y value when X = 0)
Freya begins started with 200 yards.
Freya then increased her distance by adding five yards a day for two days.
x = 200 + (n - 1)5.
<em>[x = The distance Freya sprints on day 21]</em>
x = 200 + (21 - 1)5
x = 200 + (20) 5 = 300 yards
Answer:
i believed its a=-3
Step-by-step explanation:
-2(a-3)=12
-2a+6=12
-2a=6
divide -2
a=-3
Answer: x = b + p/a
Step-by-step explanation: First add b to both sides to get ax = b + p.
Now divide both sides by a to get x = b + b/a.
