Answer:
x = -2
Step-by-step explanation:
-3(4x + 2) = 18
Divide by -3:
-3(4x + 2) / -3 = 18 / -3
4x + 2 = -6
Subtract 2:
4x + 2 - 2 = -6 - 2
4x = -8
Divide by 4:
4x / 4 = -8 / 4
x = -2

Step-by-step explanation:
2(n+2)=4n+1-2n
Whats the answer
Answer:
no solution
Step-by-step explanation:
Given
2(n + 2) = 4n + 1 - 2n ← distribute parenthesis on left side
2n + 4 = 2n + 1 ( subtract 4 from both sides )
2n = 2n - 3 ( subtract 2n from both sides )
0 = - 3 ← not possible
This indicates the equation has no solution
The original equation 2(n + 2) = 4n + 1 - 2n has no solution for n.
To solve the equation 2(n + 2) = 4n + 1 - 2n, we can simplify and then solve for the variable n.
First, distribute 2 to the terms inside the parentheses:
2n + 4 = 4n + 1 - 2n
Next, combine like terms on the right side:
2n + 4 = 2n + 1
Now, subtract 2n from both sides to isolate the n term:
2n - 2n + 4 = 2n - 2n + 1
4 = 1
Since 4 is not equal to 1, there is no solution to this equation.
Therefore, the original equation 2(n + 2) = 4n + 1 - 2n has no solution for n.

HURRY PLEASE When 5 and 6 are multiplied by the same factor, how do the ratios compare to the ratio 5:6? The ratios are equivalent to 5:6. The ratios are equivalent to 6:5. The ratios are greater than 5:6, as the factors become greater. The ratios are greater than 6:5, as the factors become greater.
Answer:
The ratios are equivalent.
Step-by-step explanation:
If you multiply both 5 and 6, the ratio stays the same.
5:6 = 10:12 = 15:18 = 20:24 etc.
You can try this by dividing the larger number by the smaller number. You'll always get 1.2 as the "relationship", or ratio, is preserved.
24/20 = 1.2
15/18 = 1.2
10/12 = 1.2
6/5 = 1.2

what is the answer to 7x-35=30+6x
Answer:
x=65
Step-by-step explanation:
you have to get all variables to one side so you would subtract 6 from seven getting one and then add 35 to 30 giving you 65 :)
Answer:
x = 65
Step-by-step explanation:
7x - 35 = 30 + 6x First subtract 6x from both sides
x - 35 = 30 Then add 35 to both sides
x = 65

A music company sells CDs for a particular artist. The company has advertising cost of $4,000 and recoding costs of $10,000; Their cost for manufacturing, royalties, and distribution are $5.50 per CD. They sell the CDs to Mage-Mart for $7.20 each
Answer:
Instructions are below.
Step-by-step explanation:
Giving the following information:
Fixed costs= 4,000 + 10,000= $14,000
Unitary variable cost= $5.5
Selling price= $7.2
To calculate the number of units to be sold to break-even, we need to use the following formula:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 14,000 / (7.2 - 5.5)
Break-even point in units= 8,235 units
In dollars:
Break-even point (dollars)= fixed costs/ contribution margin ratio
Break-even point (dollars)= 14,000 / (1.7/7.2)
Break-even point (dollars)= $59,294
Now, imagine the company requires a profit of $50,000:
Break-even point in units= (fixed costs + desired profit) / contribution margin per unit
Break-even point in units= 64,000/1.7
Break-even point in units= 37,647 units
Break-even point (dollars)= (fixed costs + desired profit) / contribution margin ratio
Break-even point (dollars)= 64,000 / (1.7/7.2)
Break-even point (dollars)= $271,059
Jim and Lynn were asked to find the coordinates of the midpoint of the segment whose endpoints are R (−15, −8) and S (−5, −2). Jim used point S as ( x 1 , y 1 ). Lynn said he had to use point R as ( x1 , y 1 ). Who is correct? Explain.
Answer:
Both Jim and Lynn, as midpoint formula observes commutative property, which commutes the position of each endpoint inside the sum without altering the result.
Step-by-step explanation:
We must remember that location of midpoint of any line segment can be determined by using this formula in function of the endpoint locations:
[tex](x_{M},y_{M}) = \left(\frac{x_{R}+x_{S}}{2}, \frac{y_{R}+y_{S}}{2} \right)[/tex]
Where:
[tex]x_{M}[/tex], [tex]y_{M}[/tex] - Location of midpoint, dimensionless.
[tex]x_{R}[/tex], [tex]y_{R}[/tex] - Location of endpoint R, dimensionless.
[tex]x_{S}[/tex], [tex]y_{S}[/tex] - Location of endpoint S, dimensionless.
Both Jim and Lynn, as midpoint formula observes commutative property, which commutes the position of each endpoint inside the sum without altering the result. That is:
[tex](x_{M},y_{M}) = \left(\frac{x_{R}+x_{S}}{2}, \frac{y_{R}+y_{S}}{2} \right) = \left(\frac{x_{S}+x_{R}}{2}, \frac{y_{S}+y_{R}}{2} \right)[/tex]

Simplifying the top:
(2* a^3 * b^5)^2 * (6ab)
4* a^6 *b^10 * (6ab)
24 *a^7 * b^11
so we have
(24 *a^7 * b^11) / (-3* a^5 *b)
immediately we can simplify 24 and -3
(-8 *a^7 * b^11) / ( a^5 *b)
a^7 and a^5 can cancel into just a^2
(-8 *a^2 * b^11) / (b)
b^11 and b cancels to b^10
-8 *a^2 * b^10
so that is your answer:
