In a certain month, Mason spent 1/6 of his salary in the first three days and $800 in the following ten days and after that he w

Nesterboy [21]

<h3>Answer: $2400</h3>

========================================================

Explanation:

x = Mason's salary in dollars for that month

x/6 = one-sixth of his salary

x/6+800 = total amount spent (the x/6 dollars and $800 combined)

In total, he spent half his salary. This means he spent x/2 dollars for the month overall.

Set the two items equal to one another. Solve for x.

x/6 + 800 = x/2

6(x/6 + 800) = 6*(x/2) ... see note at the bottom of the page

x+4800 = 3x

4800 = 3x-x

4800 = 2x

2x = 4800

x = 4800/2

x = 2400

His monthly salary is $2400

1/6 of this is (1/6)*2400 = 2400/6 = 400 dollars. Add on the $800 he also spent to get a total of 400+800 = 1200 dollars spent, which is exactly one half of the $2400. The answer is confirmed.

-------

Note: I multiplied both sides by 6 to clear out the fractions. The value 6 is the LCD in this case.

Derek buys a sack of peanuts for $15.82.

To Find :

The weight of the peanuts that are in the sack.

Solution :

Let, weight of peanuts that are in the sack are x.

So, $x = \dfrac{15.82}{3.38}\\\\x = 4.68\ pounds$

Therefore, number of pounds in the sack is 4.68 pounds.

Answer:

D

Step-by-step explanation:

So we have the function:

$f(x)=ax-b$

And we want to find its inverse.

To find the inverse of a function, we need to: 1) change f(x) and x, 2) change f(x) to f⁻¹(x), and 3) solve for f⁻¹(x) for the inverse.

So, flip f(x) and x:

$x=a{f(x)-b$

Change:

$x=a {f^{-1}(x)-b$

Solve. Add b to both sides. The right side cancels:

$x+b=a{f^{-1}(x)$

Divide both sides by a:

$f^{-1}(x)=\frac{1}{a}(x+b)$

So, our answer is D.
