Answer:

Answer is 1/3

Step-by-step explanation:

If you divide the numerator and denominator by five you get 3/9

3/9 can be reduced if you divide the numerator and denominator by 3, then your answer is 1/3 (since 3 goes into 3 once, and 3 goes into 9 three times.)

Answer:

What grade are you in? You aren't supposed to do all your missing work in one day try to get onto your work currently if you have extra time do your missing work. Remember you wanna do good on it you don't wanna finish all and be stressed out because you'll have even more missing work. If you do it just to finish it won't help either. Be focused while doing it but also be free and don't bother yourself. Such as if you played valorant for 5 hours do a missing assignment then keep on playing  (that is if you already finished what you did)

I hope this helped!! I made extra sure it's correct. :))

Answer:

True

Step-by-step explanation:

Parallel lines always have the same slope, so therefore the answer is True

Answer:

True!

Step-by-step explanation:

These equations are parallel, because all equations that are parallel are going to have the same slope, and both of these equations have the same slope! If it was 5/3 and -3/5, then it would be perpindicular, because that is the negative reciprocal! I hope this helps!

Answer:

33 is 83% of 40.

Step-by-step explanation:

33/40 = 0.825

0.825 equals 82.5%

82.5% rounded is 83%.

I hope this helps!

The required value of percentage is 82.5%. Here, 33 represents approximately 82.5 percent of the total value of 40.

To find the percent, we need to determine what portion of 40 is represented by 33. We can set up a proportion to solve this problem.

Let x represent the unknown percentage.

We can set up the proportion:

33/40 = x/100

To solve for x, we can cross-multiply and then divide:

= (33 × 100) / 40

= 3300/40

Apply division operation to get:

= 82.5

Therefore, 33 is 82.5 percent of 40.

This means that 33 is equivalent to 82.5 percent of 40.

Answer:

the answer is (X,Y)=(4,5)

Answer:

Step-by-step explanation:

1) If you really meant X^2+12=40, then this simplifies to x^2 = 28, and therefore x = ±√28, or x = ±2√7.

2) If you meant X^2+12x=40:

a) Take half of the coefficient of x:  that would be (1/2)(12), or 6.  

b) Square this result, obtaining:  6² = 36

c) Add this 36 to x^2 + 12x + 40, and then subtract it:  We get:  

x² + 12x + 36 - 36 = 40, or x² + 12x + 36 = 76

We have to add 36, as indicated above, to "complete the square."

Answer:

The slope is -4/5. Hope this helps!

Step-by-step explanation

To find the slope- Look at both points, Count how many units it is from the other point. Count how many units down and how many units right. Then its rise over run. So how many units down would go ontop of how many units right. This means the answer should be -4/5
