Mary left the place called Apton and rode towards the place Brandon at the same speed for 2 hours. She reached the sign shown below. Mary continues to ride at the same speed towards Brandon. How many hours will it take for her to ride from the sign to Brandon?

Answers

Answer:

Time taken by Mary to get to Brandon = 3 hours

Note: The complete question is found in the attachment below

Step-by-step explanation:

Step 1: Determining the average speed of Mary

At the sign, it shows that Mary has travelled 30 km from Apton in 2 hours to get to the sign.

Therefore, the average speed of Mary is given by;

average speed = total distance/time taken

average speed = 30 km/ 2 hours = 15 km/hr

Step 2: determining the time taken to get to Brandon

Also, from the sign, it can be seen that Brandon is still 45 km ahead. Since Mary continues at the same speed, the time taken will be;

time taken = total distance/average speed

time taken = 45 km/ 15 km/hr

time taken = 3 hours

Answers

Answer:

Step-by-step explanation:

To have anything to a power is just multiplying the number as many times as it says to.  ex. 2^3 is two times itself 3 times. 2 x 2 x 2= 8

In your case, you need to multiply -4 x -4 because the exponents tell you how many of the number you multiply.

-4 x -4 = 16

A $20.00 pair of jeans is discounted 20%. What is the final price of the jeans?

Answers

Answer:

It should be 4 dollars I believe

Step-by-step explanation:

Answer:

It is given that a $20.00 pair of jeans is discounted 20%. We need to find the final price of the jeans. Therefore, the final price of the jeans is $16.00

Final price of the jeans = 20 - 20% of 20

Therefore, the final price of the jeans is $16.00.

Help me please :(

Answers

Answer:

y=3/2x+5/2

Step-by-step explanation:

I used the Y2-Y1/X2-X1

In this equation you can see that there are 2 points (-5,-5) and (1,4)

If you substitute, you will get

4+5/1+5

9/6 and if you simplify this, you will get 3/2

Now that we have the slope, we just have to use y=mx+b

(I'm using the point (1,4))  4=3/2(1)+b

                                         4=3/2+b

                                         5/2=b

Step-by-step explanation:

r + 8 - 5r = 2(4 - 2r) solve for r please

Answers

-4r + 8 = 8 - 4r

0 = 0 so it's like {}

Answer:

r = 0

Step-by-step explanation:

This is actually the first time I've actually had a equation with the variable equaling 0.

so first things first you have the equation:

r + 8 - 5r = 2(4 - 2r)

so you are going to add or multiply all the variable numbers together and the none variable numbers together like so:

r + (-5r) and (2*4) and (2* (-2r)) to get the equation looking like so:

8+ (-4r)= 8 -4r

you then add -4r to both sides to get this equation:

8+ ( -4r)= 8 -4r

    + 4r       +4r

8 = 8 + r

you then subtract 8 from both sides to get r:

8 = 8 + r

-8  -8

0 = r

to check substitute the 0 into r in the equation:

r + 8 - 5r = 2(4 - 2r)

0 + 8 - (5*0) = 2(4- (2*0))

8 = 8

Tada!!!
