60 minuets are in 1 hour, and it will split up times in an hour, that means that there will be cells present.

20 minutes = 2 cells

40 minutes = 4 cells

1 hour = 8 cells

1 hour 20 minutes = 16 cells

1 hour 40 minutes = 32 cells

2 hours = 64 cells

2 hours 20 minutes = 128 cells

2 hours 40 minutes = 256 cells

3 hours = 512 cells

Donnel practiced the piano 3 hours longer than Marcus. Together they practiced the piano for 11 hours. How many hours did each b
andriy [413]
Here is the equation: x+(x+3)=11 ⇒x+x+3=11


You need to get "x" by itself so minus 3 from each side

x+x+3-3=11-3 ⇒ x+x=8 ⇒ 2x=8

Divide 8 by 2

8 ÷ 2=4

x=4

So each 4 is equivalent to 4 

Lets check:

4+(4+3)=11 ⇒ 4+4+3=11 ⇒ 11=11

So that means that Marcus practiced the piano for 4 hours and Donnel practiced for 7

Really need help please help me please please
Maru [420]

Answer:

y = 3/4x + 3

Step-by-step explanation:

you should only have y in one side and everything in other side of the equation. so you will first have -4y = -3x -12 , then you'll have to divide the right part of the equation by -4 . then you will have y = 3/4x + 3
