Hello :D
$40.00 x 3 = $120.00
$20.00 x 2 = $40.00
$120.00 + $40.00 = $160.00
$400.00 - $160.00 = $240.00
There is $240.00 left in the account.
The answer to the problem are -3 and -8 because the two equation are being solved for 0

General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
18/13 = 3/4x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide both sides by 3/4: x = 24/13
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 18/13 = 3/4(24/13)
- Multiply: 18/13 = 18/13
Answer:
14
f(x) = 7
-7^2 + 9(7)= -49 + 63 = 14
The answer is 20. You use 20 markers for it all.
