Find the reciprocal of 3/5
Kisachek [45]
The reciprocal of 3/5 is 5/3.

To get the reciprocal of a fraction, just turn it upside down.

A fraction has a numerator, top number, and a denominator, bottom number.
To get the reciprocal of a fraction, just swap over the numerator and denominator.

If whole numbers, to get the reciprocal of whole number, just divide the whole number by 1 to make it into a fraction, then get the reciprocal of that fraction.

<span>A PRESENT FOR YOU </span>
<span>Ask someone to write a number, say a five-digit number. </span>
<span>(Can be a 2-digit.....3-digit.....4-digit....ect..... </span>
<span>Suppose the number written is </span>
<span>57836 </span>
<span>Now, without showing the asker, you write a number on </span>
<span>a sheet of paper and keep it folded. You have to write the </span>
<span>number by subtracting 2 from the above number and </span>
<span>adding 2 in front which will be.... </span>
<span>257834 </span>
<span>Next, ask the person to write another five-digit number </span>
<span>below his original number. Suppose he writes 37589. </span>
<span>So you now have... </span>
<span>57836 </span>
<span>37589 </span>
<span>Now you write a five-digit number below it in such a </span>
<span>way that each digit is 9 minus digit above. You now have... </span>
<span>57836 </span>
<span>37589 </span>
<span>62410 </span>
<span>Ask the person to add one more 5-digit number. If he </span>
<span>adds 54732, you add below it 45267. Note that you decided </span>
<span>the number by subtracting each of his digit from 9. </span>
<span>Thus, you now have..... </span>
<span>57836 </span>
<span>37589 </span>
<span>62410 </span>
<span>54732 </span>
<span>45267 </span>
<span>Next, ask him to add all the number and he gets 257834 </span>
<span>Show him the number which you had written as an answer </span>
<span>to this addition earlier in the folded paper and surprise him.</span>

{ x - 3y= -3 &amp; x + y= 5 We are to use the graph to solve the given system of equations, then enter your solution below. I ge
nasty-shy [4]

Answer:

Solution: (3, 2)

Step-by-step explanation:

It's easier to graph when the equation of the lines are in their slope-intercept form, y = mx + b.

<u>x - 3y = -3</u>

-3y = -x - 3

Divide both sides by -3:

\frac{-3y}{-3}  = \frac{-x - 3}{-3}

y = 1/3x + 1

where slope = 1/3

y-intercept = 1

<u>x + y = 5</u>

Subtract x from both sides to isolate y:

x - x + y = - x + 5

y = -x + 5

where slope = -1  

y-intercept, 5

I started by graphing the y-intercepts of each line. Then, I used the slope of each linear equation (rise over run) to plot the next points on the graph. In the attached screenshot of the graph, <u>x - 3y = -3</u> is the blue line, while <u>x + y = 5</u> is the green line. Their intersection occurs at point, (3, 2).

Therefore, the solution is (3, 2).

Zola is thinking of a number. If the number is divided by 7.5, the quotient is 62. what is zolas number?
____ [38]
Okay, so I would multiply 62*7.5 to get 465.

To check the solution, make sure it follows the rules as in the word problem.

If you divide 465 by 7.5 you do get 62, so the solution is 465.

Mathematically, the equation would be

x
-     = 62
7.5
I would multiply x/7.5 by 7.5/1 (to cancel it out) and 62/1  by 7.5 which is basically the same solution as above.
