Help yall girl for 30 point

Answer:

It looks like she/he didn't count the question and just gave extra points. This made me lose some brain cells

Step-by-step explanation:

Answer:

is this a true or false question? If so, it's false. To add or subtract, the bases have to match, not the exponents.

Step-by-step explanation:

Answer:

nope it doesn't matter the exponents they don't have to match but you later have to add them and add that many zeros back as the exponents

The process is:

C = 2nr

2nr = c

r (2n) = c

[tex]r = \frac{c}{2n} [/tex]

That's the answer☝️☝️☝️☝️

or maybe this one

r = 2n + c

sorry, I'm unsure, it has been too long since I studied that...

Answer:

C = 2nr

you divide by 2n both sides

that means C/2n = 2nr/2n

after that you simplify then it will be C/2n = r

r = C/2n

Answer:

Option (4)

Step-by-step explanation:

Area of a rectangle = Length × width

If the dimensions of the given rectangle is doubled,

Area of the new rectangle = 2(Length) × 2(width)

                                            = 4(Length × width)

                                            = 4(x)(x - 2)

                                            = 4[x² - 2x]

                                            = 4x² - 8x

Therefore, Option (4) will be the correct option.

Answer:

[tex]2w - \frac{ 7}{4} [/tex]

Step-by-step explanation:

[tex] \frac{1}{4} \times 8w = 2w \\ \frac{1}{4} \times ( - 7) = \frac{ - 7}{4} [/tex]

Answer: 2w -7/4

Step-by-step explanation:

    1 /4(8w  − 7)  

Apply the distributive property.

    1 /4(8w  − 7)  + 1/4  ⋅  − 7

Cancel the common factor of 4.

Factor 4 out of 8w.

     2w + 1/4 ⋅ -7

Combine  1/4 and -7

    2w + ((-7)/4)

Move the negative in front of the fraction.

    2w − 7/4

Answer:

2400%

Step-by-step explanation:

Answer: 2,400%

Step-by-step explanation:

1.25 * 100/0.05 = 2,500

2,500% - 100% = 2,400%

Answer: 57 cents each

Answer:

57 cents

Step-by-step explanation:

divide the amount of money by the amount of oranges to find the amount each of them are. so if each of them are 57 then 1 is 57.

Statistics - Scatterplots

Step-by-step explanation:

According the data set on the graph, we can see that if we draw a line of best fit, the overall data would be increasing. Therefore, we would have a positive correlation.

Answer:

C

Step-by-step explanation:

Answer:

C. 3n+9>21

Step-by-step explanation:

Ignore the 9 for a second and think about the phrase "3 times a number", if we say n is the number, then 3n is 3 times the number n.

Now we need something that is 9 more than this 3n, that means you add 9 to this, so you have 3n+9.

Finally, this 3n+9 is greater than 21, so we have 3n+9>21.

Answer: 8

if you're talking about how many bags of sweets you can BUY, as in without counting the ones you got for free, it's 6. if you're talking how much you GOT, it's 8.

Step-by-step explanation:  you can multiply 1.5 times an unknown number to get nine. the unknown number would be the number of bag of sweets you get without the "buy 3 get 1 free" thing. You can reverse the equation to get 9 divided by 1.5 equals 6.

you can then divide 6 by three, which is 2- meaning you got two free bags of sweets. 6 plus 2 is 8.

Answer:

8 I believe

Step-by-step explanation:

1.50 x 3 = 4.50 so for 4 bags you need 4.50

1.50 x 6 = 9 but you can't forget about the buy 3 get 1 deal

you bought 6 which is two times 3 so would get two free

6+2= 8

Answer/Step-by-step explanation:

Shari's equation, 288x - 4y = -192, was stated in the standard form.

Thus, she thinks -192 was the y-intercept because:

She thought that the [constant term] is always the y-intercept. She forgot to [write the equation in slope-intercept form].

Let's find the correct y-intercept (b), by first rewriting the equation, 288x - 4y = -192, to get the equation in slope form, y = mx + b.

Thus:

288x - 4y = -192

-4y = -288x - 192 (subtraction property of equality)

y = -288x/-4 - 192/-4

y = 72x + 48

Thus, the y-intercept = b = 48

Answer:

1336miles.

Step-by-step explanation:

From the question we are told that;

1km represents 0.62miles

1km = 0.62miles

We are to express 2155kilometers in miles.

2155km = x miles

Find x:

Divide both equations;

1/2155 = 0.62/x

Cross multiply;

1 * x = 2155 * 0.62

x = 1,336.1miles

Hence the correct option is 1336miles.

Answer:

The number of dimes  is represented by x = 90

Step-by-step explanation:

Given that:

The number of dimes  is represented by x

Number of quarters = 6  + 2x

Total number of coins in the bag = 276

To find x, we have:

x + 6 + 2x = 276

3x + 6 = 276

3x = 276 - 6

3x = 270

x = 270/3

x = 90
