Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

8(2x + 5) = 16x + 40

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute 8:                                  16x + 40 = 16x + 40
  2. Subtract 40 on both sides:          16x = 16x
  3. Divide 16 on both sides:               x = x

Here we see that <em>x</em> does indeed equal <em>x</em>.

∴ <em>x</em> has an infinite amount of solutions.

your water hose is leaking at a rate of 0.25 cups per hour how many gallons did your hose leak in a full 24 hour day
abruzzese [7]
First I found it was leaking 1 cup every 4 hours then I found out that it leaked 6 cups that day and I found out that there's 16 cups in a gallon so converted 6 cups into gallons and got 0.375 of a gallon
.25 \times 4 = 1 \\ 24 \div 4 = 6 \\ 4 \times 2 \times 2 = 16 \\6 \div 16 =0.375
