Answer: $x=1/3$

Subtract 1 from both sides

$3x+1-1=2-1\\3x=1$

Divide both sides by 3

$3x/3=1/3$

$x=1/3$

Argue against the phrase,

Crazy boy [7]

Answer: It depends.

Step-by-step explanation:

If you are adding two negatives those two negatives will not give you a positive and if you are subtracting negatives depending on the numbers it wont give you a positive. Now when you multiply or divide two negatives that's a different story, but adding and subtracting negatives wont give you a positive.

Help me... with explanation plz...

stich3 [128]

Answer:

$w=3$

Step-by-step explanation:

You can write a few equations for this situation.

This is a rectangle, and rectangles have right angles. That means that the given diagonal distance makes a right triangle with the length and width.

Solve for w using the pythagorean theorem:

$w^2+(w+2)^2=5.83^2\\w^2+w^2+4w+4=33.9889$

I'm pretty sure 33.9889 is actually 34, the reason it isn't is because 5.83 was rounded to only 2 decimal places, which doesn't accurately show represent what it's supposed to be. The problem also has you round to the nearest inch, so the answer wouldn't change. It just makes the calculations significantly easier.

$2w^2+4w+4=34\\2w^2+4w-30=0\\2(w^2+2w-15)=0\\2(w-3)(w+5)=0\\w=3,-5$

Distances can't be negative, so $w=3$ .
