If Jan jogged 8x−21 miles and Julie jogged 24x−63 miles, how many times longer was Julie's travel distance than Jan's? A.3 B.16 C.24 D.63

Answer: C) 25%

Step-by-step explanation:

Answer:

60.4miles/hr

Step-by-step explanation:

Given parameters:

 Distance covered by the car = 145miles

 Time taken  = 2.4hrs

Unknown:

Average speed of the car  = ?

Solution:

Average speed is the rate of change of distance with time;

   Average speed  = [tex]\frac{distance}{time}[/tex]

Input the parameters and solve;

   Average speed  = [tex]\frac{145}{2.4}[/tex]  = 60.4miles/hr

H^2= 441+64

H^2=505

[tex] \sqrt[2]{505} [/tex]

H=22.4

Answer:

[tex]\huge{\boxed{\sf{ -20i^{2} + 48i - 16}}}[/tex]

Step-by-step explanation:

( 8 - 4i ) ( 5i - 2 )

Use the distributive property to multiply each term of the first binomial by each term of the second binomial.

⇒[tex]8 ( 5i - 2 ) - 4i ( 5i - 2 )[/tex]

⇒[tex]40i - 16 - 20i^{2} + 8i[/tex]

Combine like terms.

Like terms are those which have the same base.

⇒[tex]- 20i^{2} +40i+ 8i - 16[/tex]

⇒[tex]-20i^{2} + 48i - 16[/tex]

Hope I helped!

Best regards!

Answer:

x-12=13

X=12+13

=25

Jaden is 25 yrs old

Answer:

x + 13 = 25

Step-by-step explanation:

Since Jaden was 13 12 years ago, you should know to make the equation x + 13 = 25. How I got 25? Well 13 plus 12 is 25.

Answer:

x= 5 -y/2

y=10-2x

Step-by-step explanation:

solve for Y                solve for X        

2x + y= 10                   2x+ y=10              subtract y from each side

-2x        -2x                       -y=10 -y

       y=10-2x                    2x=10 -y

                                        2x/2=  10 -y/2  multiply both sides by 2

                                              x= 5 - y/2

Answer:

t = 4.2 h

Step-by-step explanation:

We can calculate the time taken by the car to travel 400 miles, easily by taking a difference of time in graph between 0 miles and 400 miles value:

t₄₀₀ = 3.5 h - 0 h

t₄₀₀ = 3.5 h

Now, we calculate the constant speed of the car from the following formula:

s = vt

v = s/t

where,

v = velocity of the car = ?

s = distance covered by the car = 400 mi

t = time taken = 3.5 h

Therefore,

v = 400 mi/3.5 h

v = 114.28 mi/h

Now, for this uniform speed the time taken to cover the distance of 480 miles will be:

114.28 mi/h = 480 mi/t

t = (480 mi)/(114.28 mi/h)

t = 4.2 h

Answer:

0

Step-by-step explanation:

-2-(-4)-2

We can break down the problem first. The beginning of the problem is...

-2-(-4)

Two negatives make a positive. An equivalent way to say this is

-2+4

-2+4=2

Next, we can solve for the last part. At the end of the equation, you have to subtract 2, so that's what we'll do!

2-2=0

The answer to this is 0!

I hope you understood the explanation...have an amazing day!!!! :3

Step-by-step explanation:

Answer: About 14 liters of gasoline is required.

Step-by-step explanation:

On the map,

1 centimeter= 25 kilometers.

Distance the towns along the highway is 4.5 centimeters.

Actual distance = 4.5 x 25 km

= 112.5 km

Tori's car uses 0.123 liter of gasoline for each kilometer of highway driving.

Total gasoline required = 0.123  x  112.5 km

= 13.8375 liters≈ 14 liters

hence, about 14 liters of gasoline is required.

Answer:

2.4 cm

Step-by-step explanation:

The scaled dimension on the drawing [tex]=[/tex] (Scale-factor) [tex]\times[/tex] (Original dimension)

She decides to draw 1cm for the original length of 0.5m=50 cm.

For this, the scaled dimension on the drawing=1cm and

the original dimention=50 cm

So, the scale-factor = 1/50.

As the kitchen door is 1.2m wide, i.e the original width of the door is 120 cm.

So, the scaled width of the door is

[tex]120\times \frac{1}{50}=2.4 cm.[/tex]

Hence, on the drawing, the width of the kitchen door should be 2.4 cm.

a = -1/2

Hope this helps :)

Answer:

a = -1/2

Step-by-step explanation:

-1/4a - 4 = 7/4a - 3

-a/2^2 - 4 = 7/ 2^2 a - 3

(-a) - ( 2^2) 4 / 2^2 = 7a/ 2^2 - 3

a = -1/2

I know this confusing but this how I got the answer.

I hope this helps
