Answer:
x=-2/5
Step-by-step explanation:
4(-3x-1)=13x+6 ~ Distribute the 4 into the parenthesis
-12x-4 = 13x+6 ~ add 12x to both sides
-4= 25x + 6 ~ subtract 6 from both sides
-10 =25x ~ divide by 25
-10/25 = x ~ simplify the fraction by dividing the num. and den by 5
-2/5 =x
Answer:
Step-by-step explanation:
When you add, multiply or subtract polynomials, the operation results in another polynomial.
When dividing polynomials, the operation may not result in another polynomial. In this case you normally end up with rational expression in the fraction form.
This operation is said not closed.
In our case this is option D.

<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = ∛(x - 4)
f(-121) is x = -121
f(31) is x = 31
<u>Step 2: Evaluate</u>
f(-121)
- Substitute in <em>x</em>: f(-121) = ∛(-121 - 4)
- [Radical] Subtract: f(-121) = ∛(-125)
- [Radical] Evaluate: f(-121) = -5
f(31)
- Substitute in <em>x</em>: f(31) = ∛(31 - 4)
- [Radical] Subtract: f(31) = ∛27
- [Radical] Evaluate: f(31) = 3

Answer: 140 Hot dogs and 83 sodas.
Step-by-step explanation:
Alright, so we will say that h = hot dogs and s = sodas.
h + s = 223
I have used the guess and test strategy to get:
h = 140
140 - 57 = 83
s = 83
Check: 83 + 140 = 223
