If I can paint a wall in 20 min and my friend can paint a wall in 30 min. How many minutes would it take for us to paint a wall

ra1l [238]

Answer: $12\ \text{min}$

Step-by-step explanation:

Given

It takes 20 min and 30 min for a person and his friend to paint a wall individually i.e.

In 1 min they cover $\frac{1}{20}$ part and $\frac{1}{30}$ part of wall respectively.

If the work together, 1 minute work is

$\Rightarrow \dfrac{1}{20}+\dfrac{1}{30}\\\\\Rightarrow \dfrac{3+2}{60}\\\\\Rightarrow \dfrac{5}{60}$

Time required will be reciprocal of it

$\Rightarrow \dfrac{60}{5}=12\ \text{min}$

What is the solution to the inequality - 6x + 5 > -1

ExtremeBDS [4]

[ Answer ]

$\boxed{X \ < \ 1}$

[ Explanation ]

Solution To Inequality: - 6x + 5 > -1

-------------------------------------

Subtract 5 From Both Sides

- 6x + 5 - 5 > -1 - 5

Simplify

-6x > -6

Multiply Both Sides By -1 (Reverse Inequality)

(-6x)(-1) < (-6)(-1)

Simplify

6x < 6

Divide Both Sides By 6

$\frac{6x}{6}$ < $\frac{6}{6}$

Simplify

X < 1

$\boxed{[ \ Eclipsed \ ]}$
