Pls answer 18 20 and 22 show your work
Svetlanka [38]

Answer:

18- 300

20- 1,500

22- 300

Step-by-step explanation:

You can easily find the answer like this:

18. Multiply 60 and 100 together. The hundred is from 100%. After that, divide it by 20 because of the percent. After doing this, you should get 300.

20. 360*100=36,000 36,000/24= 1,500

22. 9*100=900 900/3=300


I hope this is what you were looking for. If you need more out of this, ask me to answer it again. :)

Complete the inequality.<br> (-9/8)/(-2 3/4) ? 3/22<br> &gt;<br> &lt;<br> =
Thepotemich [5.8K]

Answer:

(-3/8)/(-2 3/4) = 3/22  

Step-by-step explanation:

Solve the following;

\frac{\left(-\frac{3}{8}\right)}{\left(-2\frac{3}{4}\right)}

=\frac{\left(-\frac{3}{8}\right)}{\left(-\frac{11}{4}\right)}

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{-b}=\frac{a}{b}

=\frac{\frac{3}{8}}{\frac{11}{4}}

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}

=\frac{3\cdot \:4}{8\cdot \:11}

\frac{3}{22}

Thus, \frac{\left(-\frac{3}{8}\right)}{\left(-2\frac{3}{4}\right)} = \frac{3}{22}

A line passes through the point (4 ‐6) and has a slope of ‐3/4 what is the equation
mrs_skeptik [129]

Answer:

y= -3/4x - 3

Step-by-step explanation:

-3/4 is the slope, so you replace m with the slope.

The y intercept is -3. If x is 4, and y is -6, we can plug that into an equation to find the y intercept. y=mx+b can change to -6= -3/4 * 4 + b. B = -3.
