Answer:

160 tiles.

Step-by-step explanation:

First let's make an equation.

Each tile costs $4, let's make <em>t=number of tiles.</em>

+$15.82, and the total cost being $655.82

So ideally our equation would look like

<em>4t+15.82=655.82</em>

<em />

Now solve.

First, subtract <em>15.82 </em>on both sides.

<em>4t=640</em>

Second, divide <em>4 </em>on both sides to make the variable <em>t </em>by itself.

<em>t=160</em>

<em />

So, the contractor purchased 160 tiles.

Absolute Value is always positive.<br><br> True<br> False
kramer

Answer: False

Step-by-step explanation: Absolute value means <em>distance from zero</em> on a number line. A common mistake is to assume that absolute value is always positive but that's not necessarily the case.

Take 0 for example.

It's 0 units away from zero on a number line which

means it has an absolute value of zero.

However, all other numbers besides zero will have

an absolute value that is positive.

The perimeter of a parallelogram is 72 meters. The width of the parallelogram is 4 meters less than it length. Find the length a
lesya [120]

P = L + L + w + w

72 = 2(L) + 2(L-4)

Distribute

72 = 2(L) + 2(L) - 8

Add like terms

72 = 4(L) - 8

Subtract 8 from both sides

64 = 4(L)

Divide both sides by 4

16 = L

The length is 16. Now substitute that in the equation for finding w.

w = L - 4

w =
