Which of the following equations do not represent a proportional relationship? y = 4/3x y = 2x - 1 y = x y = 1.4x

Answer:

[tex]-64y^{2}[/tex]

Step-by-step explanation:

You first multiply (-4)^3, then add the exponents of y, which is [tex]y^{2}[/tex].

Answer:

-4^3*y^2

Step-by-step explanation:

Because there are 3 “-4”s being multiplied it would be to the power of 3.

Because there are 2 ”y”s being multiplied it would be to the power of 2

Then you just need to multiply them together.

Answer:

Students in 7th grade took a standardized math test that they also had taken in 5th grade. The results are shown on the dot plot, with the most recent data shown first.

Find and compare the means to the nearest tenth.

7th-grade mean:

✔ 16

5th-grade mean:

✔ 13.4

What is the relationship between the means?

✔ The 7th-grade mean is about 2.5  points higher.

Step-by-step explanation:

Mean for 7th Grade Students is: 16

Mean for 5th Grade Students is: 13.4

Comparing the means, the mean for 7th grade students is 2.6 higher than 5th grade students.

The mean is the average of the data set, that is the sum of each data value divided by the number of data points.

Given that, 7th Grade Students in 7th grade took a standardized math test that they also had taken in 5th grade.

Mean for 7th Grade Students:

Mean = [10 + 11 + (2 × 12) + 13 + 14 + (2 × 15) + (3 × 16) + (3 × 17) + (2 × 18) + (2 × 19) + (3 × 20)]/21

Mean = 335/21

Mean = 15.95 = 16

Mean for 5th Grade Students:

Mean = [8 + (2 × 9) + (2 × 10) + (2 × 11) + (2 × 12) + (2 × 13) + 14 + (3 × 15) + (2 × 16) + 17 (2 × 18) + 19

Mean = 281/21

Mean = 13.38 = 13.4

The difference between their means = 16 - 13.4 = 2.6.

Hence, Mean for 7th Grade Students is: 16

Mean for 5th Grade Students is: 13.4

Comparing the means, the mean for 7th grade students is 2.6 higher than 5th grade students.

Answer:

60

Step-by-step explanation:

300 divided by 100, gives you the 1% (which in this case is 3)

3 x 80 (markup) gives you 240

300- 240(markup) gives you 60

Answer:

6x+3y

Step-by-step explanation:

3*2x=6x, and 3*y=3y

Answer:

6x+3y

Step-by-step explanation:

You have to distribute the 3 into the. parenthesies so first you would multiply the 3 and 2 then add the x at the end to get 6x + then you would multiply the 3 and the y to get 3y so in total it is 6x+3y

Answer: it is A

Step-by-step explanation:

Figures 2 & 3 have the same x value so it does not change in any way. However, the y value goes up by 4 between the two figures. Good luck!

Step-by-step explanation:

X^2y12/ xy^5

= x^2–1 • y^12–5

= xy^7

Answer:

[tex]xy^7=x^ay^b[/tex]

Step-by-step explanation:

[tex]\frac{x^2(y^3)^4}{xy^5} = x^a * y^b[/tex] = [tex]\frac{x^2(y^12)}{xy^5} = x^a * y^b[/tex]

[tex]\frac{x^2(y^12)}{xy^5} = x^a * y^b[/tex] = [tex]\frac{x^2(y^7)}{x} = x^a y^b[/tex]

[tex]\frac{x^2(y^7)}{x} = x^a y^b[/tex] = [tex]x^1y^7 = x^ay^b[/tex]

[tex]x^1y^7 = x^ay^b[/tex] = [tex]xy^7=x^ay^b[/tex]

Answer:

The greatest common factor of 12 and 54 is 6

Step-by-step explanation:

Answer:

5w+30

5(w+6)=

5*w= 5w

5*6= 30

Answer:

[tex]\huge\boxed{\boxed{5w+30}}[/tex]

Step-by-step explanation:

Hello.

The Distributive property states that

a(b+c)=ab+ac

Let's use this property to simplify:

5(w+6)

5w+30 (5 times w and 5 times 6)

And we're done!

I hope it helps & have an outstanding day!

Answer:

Step-by-step explanation:

5-1=4

Answer:

She has wrapped 15 packages.

Step-by-step explanation:

Heres how I did it. I used my fingers for this, it's a little odd I know but it works. I put up one finger for each half. So each finger represents one half. I needed to get to 2 1/2 so I put up two finger and I said "that's one " because a half plus a half is a whole or just one. Then I put up one more finger and I said " That's one and a half". I then put up two more and then I had 2 1/5. What I did then was count how many fingers I had up. I had 5 fingers up. So then I multiplied 3 x 5 and that gave me 15. Hope I could help!

Hey there!

2^2 + 5 + 50 ÷ 2(5)

2^2 = 2 • 2 = 4

4 + 5 + 50 ÷ 2(5)

4 + 5 = 9

9 + 50 ÷ 2(5)

50 ÷ 2 = 25

9 + 25(5)

25(5) = 125

9 + 125

= 134

Answer: 134 ☑️

Ok!

Step-by-step explanation:

Answer:

1. 6/15, or 2/5.

2. Apples cost more per pound.

Step-by-step explanation:

1. Brian reads 2/15 in 20 minutes, like we were told. It's easy to determine how much of his book he can read within an hour, by using the ratio 1/15:10. There's clearly 1/15 in 10 minutes, 2/15 in 20, 3/15 in 30, and so on. This would result in him reading 6/15's of his book in an hour.

2.

Peaches

0.6÷8/5 converts to .6 × 5/8. The result is .375.

Apples

1.75 ÷7/2 converts to 1.75×2/7. The result of this equation is .5, so therefore, the apples cost more per pound.

Answer:

-0.5 is probably right I'm not 100% sure

Answer:

.75

Step-by-step explanation:

You have to do B * H / 2   which 1.5 x 1 = 1.5, and then 1.5/2 = .75
