Answer: 7
Step-by-step explanation:
Because we would do 35-
28
Basically you just add 5000 + 7000
=12000
Answer:
x = infinite amount of solutions
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
- Solving systems of equations by graphing
Step-by-step explanation:
<u>Step 1: Define systems</u>
y = 2/3x + 4
2x - 3y = -12
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 2x - 3(2/3x + 4) = -12
- Distribute -3: 2x - 2x - 12 = -12
- Combine like terms: -12 = -12
Here we see that -12 does indeed equal -12.
Therefore, our <em>x</em> would equal infinite amount of solutions.
<u>Step 3: Graph systems</u>
<em>Check the systems.</em>
We see that the 2 lines are the same.
Let +n+ = number of bottles of cranberry juice needed
+2n+ = number of bottles of ginger ale needed
---------------------------
+3.2n+%2B+.9%2A%28+2n+%29+=+20+
+3.2n+%2B+1.8n+=+20+
+32n+%2B+18n+=+200+
+50n+=+200+
+n+=+4+
and
+2n+=+8+
----------------
The most bottles of cranberry juice is 4
Answer:
x - 9
Step-by-step explanation:
First, distribute:
-3x - 9 + 4x
Then, simplify (add up x):
x - 9
And we're done ^^
