Amy:  (3 pages/min)(x min) + 9 pages
Sam:  (2 pages/min)(x min)  + 47 pages

Equate these:  3x+9 = 2x + 47

Then x = 38.  The two friends will have covered the same number of pages after 38 minutes.  How many pages would that be?  3(38)+9 = 123 pages.

Liula [17]
Peppermint to chocolate is 5:3, so5p=3c, and peppermints to gummies is 3:4, so 3p = 4g.

5p = 3c
*3     *3

15p = 9c
---------------
3p = 4g
*5      *5
15p = 20g
---------------
15p = 9c
15p = 20g
9c = 20g, so chocolates to gummies is 9:20.

Does anyone know the answer?
Ludmilka [50]

Answer:

x=120 degrees

Step-by-step explanation:

Because these two angles share the two same points, either one is 2x larger or 2x smaller than the other. X is the larger angle, therefore is 2x larger than 60. 60×2=120. I hope this helps you!

frosja888 [35]
The answer to this question is letter C

We can approach this by first finding the rate of feet per second traveled.

240(feet)/30(seconds)= 8 feet per second.

This answer resembles the slope for answer choice C.

To find the distance traveled in 10 seconds we do 10*8= 80 feet.

I hope this helps, please like and brainliest if correct, thank you!

Solve the following equations. You will need to show your work in order to receive full credit.
vodomira [7]

Hello from MrBillDoesMath!

Answer:   x =  10 for 4x - 8 = 32

               x = -5  for 2(x-5) = -20

Discussion:

------------------------------

4x - 8 = 32    (*)

Add 8 to both sides:

4x - 8 + 8 = 32 + 8 =>

4x = 40 =>

x = 10


-----------------------------------------------

2(x-5) = 2x - 2(5)  =>

2x - 10 = -20 (**)

Add 10 to each side of (**):


2x - 10 + 10 = -20 + 10 =>

2x = -10

x = -5




Thank you,

MrB
