Answer:
x ≥ 8
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define inequality</u>
-36x - 24 ≤ -6(5x + 12)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -6: -36x - 24 ≤ -30x - 72
- Add 36 on both sides: -24 ≤ 6x - 72
- Add 72 on both sides: 48 ≤ 6x
- Divide both sides by 6: 8 ≤ x
- Rewrite: x ≥ 8
Here we see that any number <em>x</em> greater than or equal to 8 would work as a solution.
Answer:
The 10 dollars for 25 tickets
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
We want to find the equation of a line with a slope of 3 that includes the point (0, 5).
We can use the slope-intercept form, given by:
Where m is the slope and b is the y-intercept.
Notice that the given point (0, 5) is already the y-intercept. So, b = 5.
By substitution, we acquire:
Hence, our answer is B.
Answer:
NaOH(s) --> Na+(aq) + OH–(aq)
Step-by-step explanation:
A basis of Arrhenius is a substance that, when dissolved in an aqueous solution, increases the concentration of hydroxide, or OH-, ions in the solution.
So the answer is :
NaOH(s) --> Na+(aq) + OH–(aq)
