7/30+9/20 what is the answer pls hurry im so confused

Svetradugi [14.3K]

Here is your answer:

$\frac{7}{30} + \frac{9}{20}$
Find common denominator:
$30 \times 20 = 60 /20 \times 30 = 60$
Common denominator is 60:
$\frac{7}{30} + \frac{9}{20} = \frac{140}{60} + \frac{270}{60}$
$140 + 270 = 410$
$= \frac{410}{60}$
$\frac{410}{60} \div 2 = \frac{205}{30} \div 5 = \frac{41}{6}$
= $\frac{41}{6} or 6\frac{5}{6}$

Hope this helps!

What is the inverse of the function f(x) = 2x – 10?

Lana71 [14]

Answer:

$h(x)=\dfrac{x}{2}+5$

Step-by-step explanation:

You are given the function $f(x)=2x-10$ . To find the inverse function $f^{-1}(x)$ do such steps:

1. Rewrite the function f(x) as

$y=2x-10$

2. Express x in terms of y:

$y+10=2x\\ \\x=\dfrac{y}{2}+5$

3. Change x into y and y into x:

$y=\dfrac{x}{2}+5$

Now, the inverse function is

$f^{-1}(x)=\dfrac{x}{2}+5$
