The mall is 6 miles far from there school.

Step-by-step explanation:

Given:

Marshall and Mimi walk the same distance from the school to the shopping mall. Marshall walked 2 mph while Mimi left one hour later and walked 3 mph.

If they reached the mall at the same time.

Now, to find the distance from the mall to there school.

Let the time be

As, the speed of Marshall = 2 mph.

So, the distance of Marshall =

Now, Mimi left one hour later and walked 3 mph.

Let the time of Mimi be

Speed of Mimi = 3 mph.

Thus, the distance of Mimi =

As, given Marshall and Mimi walk the same distance from the school to the shopping mall and they reached the mall at the same time.

According to question:

Adding both sides by 3 we get:

Subtracting both sides by 2 we get:

Now, to get the distance from the mall to there school we substitute the value of :

Therefore, the mall is 6 miles far from there school.

correct answer:

b.(19,-2)

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
