How to solve -8-x=x-4x
MAVERICK [17]
Okay. So for this question, let's combine like terms on the right side first to simplify the expression. x - 4x is -3x. The expression simplified is this:

-8 - x = -3x.

Now, we add x to both sides to cancel out the x on the left. -3x + x is -2x. That leaves us with -8 = -2x. Divide each side by -2 to isolate the x. -2x/-2 cancels out. -8/-2 is 4. Let's plug in the value as x to see if it works. -8 - 4 is -12. -3 * 4 is -12. -12 = -12. There. x = 4.

4x - 5= 2(2x - 1) -3
Alekssandra [29.7K]

Answer and Step-by-step explanation:

Solve for x.

Distribute the 2.

4x - 5 = 4x - 2 - 3

Combine like terms

4x - 5 = 4x - 5

Add 5, and subtract 4x.

0 = 0

There are infinitely many solutions, meaning any value plugged in for x will result in the equation being true.

Ari is designing a patio that will be 20 feet long and 16 feet wide. He makes a scale drawing of the patio using a scale of 1 in
Anna007 [38]

Answer:

80 square feet

Step-by-step explanation:

This time I will get it right for sure!

So first we need to find the area in feet, and then convert it in to inches.

1) Since the patio has the shape of a rectangle, then the formula is:

A = a * b

A = 20 * 16

A = 320 feet

2). Now we have to find the ratio, so:

320 / 4 = 80

So, the answer is

1 square inch to 80 square feet.

Hope this helps))
