Change the fraction to a percentage first. It'll be easier.

1/5 is equal to 20%.
"What is 20% of 75?" is now the question.

Now, we set up the problem.

\frac{part}{whole} = \frac{percent}{100}

The part will be 'x', since it is unknown, and 75 is the whole. 20% (1/5) will be the percent, obviously.

Here's a tip: If you can't find what the whole is, it usually follows 'of'.

Fill in the blanks.
\frac{x}{75} = \frac{20}{100}\\\\cross\ multiply\\\\75\times20=1500\\100\times x=100x \\\\1500=100x\\x=15


15 is 1/5 of 75.

Can someone help me with this homework?
Gemiola [76]

Answer: (-4, -1)

Step-by-step explanation:

Starting at point (-4, -2) and translating 3 units up means we add 3 to -2.

So the new point is now (-4, 1).

Now we reflect over the x-axis which means the y-value of 1 becomes negative.

So the final point is (-4, -1)

Identify the slope-intercept form and the graph of the line described by the equation 2x−y=0.
vitfil [10]

Answer: y=2x

Step-by-step explanation:

Let's solve for y.

Step 1: Add -2x to both sides.

2x−y+−2x=0+−2x

−y=−2x

Step 2: Divide both sides by -1.

-y/-1 = -2x.-1

y=2x

Therefore, the y=mx+b form of this question would be y=2x
