Equation to find number's value: 
Number's value: n = 35
Explanation:
Let n be the unknown number for this problem.
One fifth of a number is the same as
.
Three times the number is the same as 3n.
Twice the number plus 42 is the same as 2n + 42.
So, using the information we've gathered so far, we can create the equation that will provide us with n's value.
Equation: 
We can use this equation to find n's value.
You can subtract 2n from both sides to get the equation
, which is the same thing as the equation we were using.
Now add n and
together to get
.
After you do this, your equation should look like
.
Now divide both sides by
to get n's value.
n = 35
Answer: 4,2,3,1,5,6
Step-by-step explanation:
Plato
(3x+6)(2x^2), using the distributive property, equals 2x^2*3x+2x^2*6. We multiply the 2 with the coefficients and add a power of x if multiplied by x, getting 6x^3+12x^2
Answer:
B. (13 - 6)n - 40
Step-by-step explanation:
If each bottle costs them $6 and they are selling each one for $13, the amount of money they make for each bottle can be represented by (13 - 6)n
This is because this finds the profit per bottle, then multiplies it by n, which is the number of bottles they sell.
Then, since they spent $40 on advertising, subtract 40 from this.
The expression will be (13 - 6)n - 40.
The correct answer is B. (13 - 6)n - 40
