Answer:
x = infinite amount of solutions
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
3(x + 10) + 6 = 3(x + 12)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 3: 3x + 30 + 6 = 3x + 36
- Combine like terms: 3x + 36 = 3x + 36
- Subtract 36 on both sides: 3x = 3x
- Divide 3 on both sides: x = x
Here we see that <em>x</em> does indeed equal <em>x</em>. We can plug in any number <em>x</em> and it would render the equation true.
∴ x = infinite amount of solutions
Answer:
the answer is 1,078
Step-by-step explanation:
Y = -3x+8
y = -5x-2
------------
y = 5(-3x+8)
y = 3(-5x-2)
---------------
y = -15x+40
y = -15x-6
--------------
y = -15x+40
- -
y = -15x-6
--------------
y = 46

y = -3x+8
</span>46 = -3x+8
-8 -8
---------------
38 = -3x

Our P = 100, r = .08, n = 1 (annually means once a year), and t = 15. Filling in accordingly, we have
. Simplifying a bit gives us
and
. Raising that number inside the parenthesis to the 15th power gives us
. Multiplying to finish means that A(t) = $317.22
The GCF of 27 and 18 would be 9. It is the largest or greatest common factor that can be evenly divided by in both the numbers 27 and 18.
