Answer:
2062.50
Step-by-step explanation:
Interest = (Principle x rate x time)/100
Amount = Principle + interest
Principle = 750
Rate = 7%
Time = 25 years
(750 x 7 x 25)/100
= 131250/100
=1312.50
Principle = 750
Interest = 1312.50
Amount = 750 + 1312.50
Amount = 2062.50

Answer: 4(x - 1)(x^2 + x + 1)</h3>
==================================================
Work Shown:
4x^3 - 4
4(x^3 - 1)
4(x - 1)(x^2 + x + 1)
In the last step, I used the difference of cubes factoring formula which is
a^3 - b^3 = (a - b)(a^2 + ab + b^2)
Answer:
$50,000
Step-by-step explanation:
Let x = car sales
We multiply x by 0.02 since she earns 2% along with the added $2500 so that she can end up with $3500
3500 = 0.02x + 2500
Subtract 2500 from both sides
3500 - 2500 = 0.02x + 2500 - 2500
1000 = 0.02x
Divide both sides by 0.02
1000/0.02 = 0.02x/0.02
x = 50000
Answer:
x = -50/9
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
3x - 8 - 12x = 42
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: -9x - 8 = 42
- Isolate <em>x</em> term: -9x = 50
- Isolate <em>x</em>: x = -50/9
