Answer:

850

Step-by-step explanation:

To get my answer, I divided 150 by 17. (The survey of people and the # of them under 21) I got 8.8235. Next, I divided 7500 (the total of people in the stadium) by 8.8235 (the decimal that I got above) I got 850.

To check my answer, I divided 7500 by 850 and got 8.8235, the same ratio as the survey.

If (3x2 + 22x + 7) ÷(x + 7) = 3x + 1, then (x + 7)( ) = . The check of the polynomial division problem shows that the product of

azamat

Answer:

$(x + 7) * (3x + 1) = (3x^2 + 22x + 7)$

Step-by-step explanation:

Given

$(3x^2 + 22x + 7) \div (x + 7) = 3x + 1$

$(x + 7) * (\ ) = [\ ]$

Required

Complete the blanks

We have:

$(3x^2 + 22x + 7) \div (x + 7) = 3x + 1$

Rewrite as:

$\frac{(3x^2 + 22x + 7) }{ (x + 7)} = 3x + 1$

Cross multiply

$(x + 7) * (3x + 1) = (3x^2 + 22x + 7)$

To travel from New York to Philadelphia at 50 mph, it takes 20 more minutes than to travel the same distance at 60 mph. Find the

Lana71 [14]

Answer:the distance between the two cities is 100 miles

Step-by-step explanation:

Let x represent the distance between New York and Philadelphia.

Let t represent the time it takes to travel from New York to Philadelphia at 50 mph

Distance speed × time

time = distance/speed

To travel from New York to Philadelphia at 50 mph,

x = 50t

it takes 20 more minutes than to travel the same distance at 60 mph. Converting 20 minutes to hours, it becomes 20/60 = 1/3 hours. This means that

x = 60(t - 1/3) = 60t - 20

Since the distance is the same,

60t - 20 = 50t.

60t - 50t = 20

10t = 20

t = 20/10 = 2

Therefore

x = 50t = 50 × 2 = 100 miles
