Well, it’s quite surprising to learn that washing and drying may take up to 80 minutes.

It’ll take 5 hours and 26 mins. Here’s how: Turn 2 hours 32 mins into minutes completely: 152 mins. Take that and divide it by the amount of loads (4) to get the number of minutes it takes for each load: 38 minutes. Multiple the mins it takes for each load (38) by 7 to get 266 minutes. Subtract by 60 (because dividing will give you a decimal) to group 266 into hours. You’ll get 5 pairs of 60 with a spare if 26 which means you’ve got 5 hours and 26 minutes.

SoIve the system of equations by elimination. (Addition)<br> 1)-2x + 4y = -22<br> 2x + 8y = –26
Rufina [12.5K]

Answee:

We have these two equations:

-2x +4y =-22

2x + 8y -26

We need to try to get the same number multiplying both x or y, I think we can make the 2 of the first equation negative, for that, we multiply all the equation by -1:

2x + 8y =-26  ---- -2x - 8y =26

Now we have this:

-2x +4y = -22

-2x -8y = 26

Now e substract both equations:

-2x - (-2x) +4y -(-8y) = -22-26

12y = -48

Y = -48/12 = -4

And we replace to get x

-2x + 4y = -22

-2x +4*(-4)=-22

-2x - 16 = -22

x= -6/-2 =3

Solve in systems by substitution y=x+2 and 3x+3y=6
Vesnalui [34]

Answer:

x = 0, y = 2

Step-by-step explanation:

Substitute the first equation into the second equation so 3x + 3(x+2) = 6. Simplify this to get x = 0. Plug x = 0 back into the first equation to get y = 2.
