500.

Solution:  210 is 42% of X  

Equation: Y = P% * X  

Solving our equation for X

X = Y/P%

X = 210/42%  

Converting percent to decimal:

p = 42%/100 = 0.42  

X = 210/0.42  

X = 500

Answer:

Step-by-step explanation:

f(x) = y = 3x/(8 + x)   (I am assuming that the 8 + x is the denominator. Please use parentheses in the future if you forgot this. If there are no parentheses, then my solution will not work for you.)

 

Exchange x and y; that is, replace x by y and y by x simultaneously:

 

x = 3y/(8 + y).

 

Then use algebra to solve for y in terms of x:

 

(8 + y)x = 3y    (multiply both sides by the denominator to clear the fraction)

8x + xy = 3y     (distribute)

xy − 3y = −8x     (rearrange terms with all y's on the left side of the equation)

y(x − 3) = −8x    (factor out y as a common factor)

y = −8x/(x − 3)    (divide by x − 3)

 

Finally, replace y by f-1(x):

 

f-1(x) = −8x/(x − 3).

 

This is the inverse of f(x). It can be checked by finding f(f-1(x)) and f-1(f(x)), and verifying that both equal x after simplifying.

35/40 reducing fractions
laila [671]

Answer: 7/8

What you have to do here is to find the highest number which can be divided by both. Or you have to divide both the numerator and denominator until it can not be divided by any number anymore. You can do this by finding the highest common factor (<u>HCF)</u> of both the number, 35 and 40.

Highest Common Factor: HCF of two or more numbers is the greatest factor that divides the numbers. For example, 2 is the HCF of 4 and 6.

So, the highest number which divides 35 and 40, is 5. Now 35 divided by 5 is 7 and 40 divided by 5 is 8. The final answer is 7/8 and there is no more numbers which can divide both of them by a specific number.

kap26 [50]

Answer:0.27

Step-by-step explanation:

First, we convert the fraction to a decimal number by dividing the numerator by the denominator:

4 / 15 = 0.266

There are two parts to the decimal number above:

Integer Part: 0

Fractional Part: 266

Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*

In this case, Rule II applies, so 4/15 (or 0.266) rounded to the nearest hundredth in decimal format is:

0.27
