Answer:
z = -10
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
-4 - (z - 6) = 12
<u>Step 2: Solve for </u><em><u>z</u></em>
- Distribute negative: -4 - z + 6 = 12
- Combine like terms: -z + 2 = 12
- Subtract 2 on both sides: -z = 10
- Divide -1 on both sides: z = -10
<u>Step 3: Check</u>
<em>Plug in z to verify it's a solution.</em>
- Substitute: -4 - (-10 - 6) = 12
- Subtract: -4 - (-16) = 12
- Simplify: -4 + 16 = 12
- Add: 12 = 12
Here we see that 12 does indeed equal 12.
∴ z = -10 is a solution of the equation.
Well c is the cost to rent the locker for 1 hour, the 1.5 is the rental time, so multiplied together, you get the 9 which is the total cost to rent the locker for the number of hours you had it for.
for example: if you were to rent the locker for 1 hour (t = 1) the equation would look like c(1) = total cost.
*hopefully this is making sense*
another example: if you wanted to find out what the base rate is to rent the locker for 1 hour, you would just solve for c in the given equation
c(1.5) = 9 c = 9/1.5 c = 6
The answer is 21 your welcome
Do eighteen divide by three, that'll equal six and then multiply by eight, six times eight equals forty eight.
the whole number is forty eight
