Answer:

8 miles

Step-by-step explanation:

Given

Represent the police station with P, Library with L; Fire station with F

The first statement can be represented as:

[tex]L - P = P - F - 3[/tex]

The second can be represented as:

[tex]L - P = 5[/tex]

Required

Determine the distance between the police station and the fire station (P - F)

[tex]L - P = P - F - 3[/tex] --- (1)

[tex]L - P = 5[/tex] --- (2)

Substitute 5 for L - P in (1)

[tex]5 = P - F - 3[/tex]

Add 3 to both sides

[tex]3 +5 = P - F - 3 + 3[/tex]

[tex]3 +5 = P - F[/tex]

[tex]8= P - F[/tex]

[tex]P - F = 8[/tex]

9

Step-by-step explanation:

×=72/8

×=9

Hope it helps

Answer: 9

Step-by-step explanation: First, look for the value of x. A number with a variable in front of it means that you’ll be multiplying, but you can use division which makes it easier to find x. SO, DIVIDE 72 by 8 (82 ÷ 7), which equals to 9. (8 x 9 = 72)

Answer: C

Step-by-step explanation:

not A or d

B or C

All I did was divide 95 and 5 and I got 19!

hope this helps!:)

Answer:

B.) 7 seconds

Step-by-step explanation:

We are given that the ant can crawl 95 centimeters in 5 seconds, which means that it can crawl 19 centimeters in 1 second (95 centimeters/5 seconds). Now you need to divide 19 from 133 (133 centimeters/19 centimeters per second), and you get 7 seconds.

Answer:

A student has passed 60 percent of the 20 quizzes he has written so far successfully mean:

successfully quizzes = 60 % of 20 quizzes = ( 60 / 100 ) * 20 = 60 * 20 / 100 = 1200 / 100 = 12

The remaining quizzes = 50 - 20 = 30 quizzes

80 percent of the remaining quizzes successfully mean:

The remaining successfully quizzes = 80 % of 30 = ( 80 / 100 ) * 30 = 80 * 30 / 100 = 2400 / 100 = 24

Total successfully quizzes = 12 + 24 = 36

Average = ( 36 / 50 ) * 100 % = 0.72 * 100 % = 72 %

3. 6+3(-6)

4. 6+(3*-6)

5. 6+-18

6. -12

Answer:

Step-by-step explanation:

Set up the following ratio. Let the total number of shots = x

40/100 = 140/x               Cross multiply

40x = 100* 140               Combine the right

40x = 14000                   Divide by 40

x = 14000/40

x = 350

She took 350 shots in total.

Answer:

y=3x+10

Step-by-step explanation:

7-16=-9

-1-2=-3

-9/-3=3

m=3

Step-by-step explanation:

A circle is 360 degrees

209 is part of the circle so find the difference between 360 and 209

360 - 209 = 151

If the two angles are equivalent to 151, then we find the difference between 151 and 96 to get the measurement for angle b

151 - 96 = 55

I read now that it says use the rules above, but I'm not seeing any rules in the picture so hopefully my steps are the rules you're referring to

Answer:

2x + 7

Step-by-step explanation:

The product of 2 and x

Product means multiplication

The product of 2 and x means multiplication of 2 and x

Which is equivalent to

2 * x = 2x

The product of 2 and x is increased by 7

That is, 7 is added to the product of 2 and x

Here,

2x + 7

The variable expression that represent the word phrase "The product of 2 and x is increased by 7" is 2x + 7

Answer:

15

Step-by-step explanation:

82 + (7s - 7) = 180

   - subtract 82 from both sides

7s - 7 = 98

   - add 7 to both sides

7s = 105

   - divide both sides by 7

s = 15

30 degrees

Measure of the angle of 6 is 30 degrees

Answer:

30 degrees

Step-by-step explanation:

because 60 degrees is already there and 120 is angled the opposite way, and 100 degrees is a little farther than 90.

Find the x- and y-intercepts of the graph of each ... CCSS REASONING The equation 5x + 10y = 60 ... 20. SOLUTION: The x-intercept is the point at which the y-coordinate is 0, or the line ... charges $50 for admission before 6 p.m. and $20 for ... (90, 70). 100 f (100) = 160 – (100). 60. (100, 60). 130 f (130) = 160 – (130). 30.

Answer: I have no idea

Step-by-step explanation:

Answer:

The additional cost is $0.12 for each additional mile the van is driven ⇒ D

Step-by-step explanation:

The form of the linear function is

f(x) = m x + b, where

m is the rate

b is the initial value

In our question

The function C(d) = 0.12 d + 25 represents the cost C in dollars of the rental van uses for d miles

→ Compare it with the form of the linear function above

∴ m = 0.12

∴ b = 25

∵ The cost C depends on the number of miles d

∴ $0.12 is the cost per mile ⇒ additional cost for each additional mile

∴ $25 is the initial cost ⇒ initial cost of the moving the van

The interpretation of the slope for this function is:

The additional cost is $0.12 for each additional mile the van is driven

Answer:

+0.12

Step-by-step explanation:

The additional cost is 0.12 cents for each additional mile the van is being driven.

We have to attend 7 basketball games and 1 soccer game.

Given, we had two types of game namely basketball and soccer.

Travel time for basketball games is 2 hours and soccer games is 1 hour.

Let no. of basketball games be x and no of soccer games be y.

According to the question we would like to attend at least 8 games, so we have the inequality  [tex]x+y\geq 8[/tex]

And  we would spend no more than 15 hours traveling to the game, so [tex]2x+1y\leq 15[/tex].

[tex]x+y=8\\[/tex]

[tex]2x+1y=15\\[/tex]

On solving we get [tex]x=7[/tex] and [tex]y= 1[/tex].

Hence we have to attend 7 basketball games and 1 soccer game.

Answer:

the total would be 170 dollars

Step-by-step explanation:

200x0.15

Answer:

$170

Step-by-step explanation:

15% of 200 is 30, so subtracting 30 from 200 gets you 170.

If you're having trouble with finding 15% of 200, just flip it around, and find 200% of 15. 15% of 200 and 200% of 15 are both 30. This works no matter what numbers you have. For example, 8% of 100 and 100% of 8 are equivalent, 70% of 200 and 200 and 200% of 70 are equivalent as well.
