We have a system of equations 2x - 4y = 5 and 6x - 3y = 10.
We want to eliminate one variable when we add up the equations.
If we want to eliminate the x variable, we need to multiply the top, bottom or both of the equations with a number that when the equations are added together will eliminate the x variable.
Multiply the top equation by -3.
-3(2x - 4y) = 5 * -3
-6x + 12y = -15
Now when we add the two equations together, the x's will be eliminated.
-6x + 12y = -15
6x + 6y = 10
18y = -5
The x's were eliminated.
It's 8n meaning 8 times n (8*n) so for example for 5 nights she would sleep : 8*5 = 40 hours in total.
Calculator display for 
= 0.75
calculator display for 
= 0.41667
Calculator display for 
= 0.5833
Step-by-step explanation:
Calculator display for is 0.75
Yes , it is the exact decimal equivalent.
= 0.75
9 ÷ 12
=3 ÷ 4
= (3 × 25) ÷( 4 × 25)
= 75 ÷ 100
= 0.75
calculator display for = 0.41667
= 0.41667
It is not the exact decimal equivalent.
5 ÷ 12 = (5 × 8.35) ÷ ( 12 × 8.35)
= 41.75 ÷ 100.2
= 0.41667
Calculator display for = 0.5833
It is not the exact decimal equivalent.
7 ÷ 12 = ( 7 × 8.35) ÷ ( 12 × 8.35)
= 58.45 ÷ 100.2
= 0.5833
