47. Which of the following represents 0.2% of 1/5?

erica [24]

First think of what 0.2% is as a fraction,

$0.2\%=\frac{0.2}{100}=\frac{2\cdot10^{-1}}{10^2}=\frac{2}{10^3}=\frac{2}{1000}$

Now multiply the fraction by a fifth,

$\frac{2}{1000}\cdot\frac{1}{5}=\frac{2}{5000}$

Which then simplifies to,

$\frac{2}{5000}=\boxed{\frac{1}{2500}}$

Hope this helps :)

Solve the linear equation. X + 5 = -2

Vladimir79 [104]

Answer:

$x=-7$

Step-by-step explanation:

So we have the equation:

$x+5=-2$

To solve, subtract 5 from both sides. This is the subtraction property of equality:

$(x+5)-5=(-2)-5$

The left side cancels:

$x=(-2)-5$

Subtract on the right.

$x=-7$

So, our answer is -7.
