solve for x in the problem below and show all work
7x - 5x/3 (20/x - 8) -48=0
Answers
Let’s work this out step by step.
The first thing you want to do is move that 48 to the other side. To do that, add 48 to both sides:
7x-5x/3(20x-8)=48
Now, the equation isn’t equal to zero… so it is solvable! Remember in order of operations: PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction. So, let’s start by multiplying the (-5x/3) by the components inside the parentheses to get rid of the parentheses altogether!
7x-100x/3x+40x/3=48
Since both the numerator and denominator have an “x” in them in “100x/3x”, you can cancel out the “x”s to just get 100/3, which is 33.333333
7x-100/3+40x/3=48
Let’s get rid of that 100/3 by adding it to both sides.
7x+40x/3=81.33333333333
Transform 7x to a fraction that can be added to 40x/3 (common denominators)
7x=7x/1
7x/1* (3/3)= 21x/3
Now, add the two fractions together
21x/3+40x/3= 61x/3
61x/3=81.333333333
Get rid of the 3 by multiplying on both sides:
61x= 244
Divide by 61 to get x
X=4
Hope this helped! Comment if you have any questions!

Answer:
n = 6
Step-by-step explanation:
To solve this you can use an equation such as:
[tex]\frac{2}{3} n+4=8\\\\[/tex]
We need to so for n. Subtract 4 from both sides to get the variable (n) alone. 4 - 4 and 8 - 4 equals:
[tex]\frac{2}{3}n=4[/tex]
So now we divide both sides by 2/3.
This now equals:

Step-by-step explanation:
5/14 to the son.
that leaves 9/14 of the total.
these 9/14 we need to split into 1/3rds, as 2/3 of these 9/14 go to the daughter, and then the remaining 1/3 of these 9/14 to the wife.
how do we do that ?
well, here it is simple, as we see right away that the numerator 9 can be easily split into 1/3rds (9/3 = 3).
but in general by multiplying. so 2/3 of 8/14 is
9/14 × 2/3 = 9×2 / 14×3 = 3×2 / 14 = 6/14
and then little surprising 1/3 is
9/14 × 1/3 = 9 / 14×3 = 3/14
now, we know, these 3/14 are 36000.
what we need to know is how much is 14/14 or 1/1 : the whole amount.
well, the easiest way in my opinion is now to bring it to 1/14 (by dividing by the numerator 3) and then multiply it by 14 (the denominator) to bring the sum to the whole (14/14).
it in total, multiply it with the reverse fraction : 14/3
36000 × 14/3 = 12000×14 = 168000

Step-by-step explanation:
since you have the lengths of two sides and their included angle, you can use the law of cosines to solve for the missing side. let a, b, and c be the side lengths, and A be side a's respective opposite angle:
the law of cosines states that
a^2 = b^2 + c^2 - 2bc ∙ cosA

In f(x)=ax+b, 'a' is the slope and b is the initial value or y intercept
Given :
Given function is f(x)=ax+b
f(x)=ax+b is the linear equation
The graph of a linear equation is a line. The value of 'a' tell us the steepness of the line that is the slope of the line .
'b' is the initial value . when x=0, f(x)=a(0)+b
that is f(0)=b
So, 'b' is the initial value or y intercept.
