needs some help with this please!

Answer:

The answer is 15x+30y-220

Answer:

90 MPH

30 / (1/3) = 90

Answer:

90mph

Step-by-step explanation;

if an object travels 30 miles in the first part of an hour, and the speed is constant, then we can assume 30*3=90

in the first third, it went 30 mi, in the second it went 30mi, and in the last part it went 30 mi

30+30+30=90

or you could do 30* the denominator (in this case its 3), so 30*3=90

Sorry if this doesn't make sense, hope it helps though!

Answer:

A

Step-by-step explanation:

The formula for circumfrence is C=pi x 2r or C= pi x r

In this case its C= 3.14 x 9 which is 28.26 rounded to 28.3

Answer:

Answer A is correct.

Step-by-step explanation:

Formula to find the circumference of a circle is :

C = π × d

Here,

d ⇒ diameter ⇒ 9m

First, let us find the circumference in terms of π.

C = π × d

   = π × 9

    = (9π)m

And now let us find the circumference to the nearest 10th.

Given that,

π = 3.14

Let us find now.

C = 9π m

   = 9 × 3.14 m

    = 28.26 m

    ≈ 28.3m

Answer:

-1/4

Step-by-step explanation:

Since there is a positive and negative sign next to each other it would automatically become a negative sign so then your equation should be 1/2-3/4 now you would need to find the common denominator since 2 can go into 4 2x the equation would be 2/4-3/4 now you would subtract that to get -1/4

Answer:

|-655|= 655

Step-by-step explanation:

Example: The absolute value of |x|= to either;

+x - if x is >0

-x - if x is < 0

0 - if x=0

---------------------------------

In this case, we are finding the expression that represents the absolute value of "-655".

---------------------------------

|-655|= 655

Answer:

[tex]A.\ y-4=3(x-1)[/tex]

Step-by-step explanation:

[tex]A.\ y-4=3(x-1)\\\\B.\ 1-y=3(x-4)\\\\C.\ y^1-4=3(1=x1)\\\\D.\ 1-y1=3(4-x1)x^{2}[/tex]

[tex]A.\ y-4=3(x-1)\\\\A.\ 4-4=3(1-1)\\\\A.\ 0=3(0)\\\\A\ 0=0[/tex]

This statement is correct

Therefore, A is the correct answer.

Hey there!

ORIGINAL EQUATION:

1/2y + 1 = 2

SUBTRACT 1 to BOTH SIDES:

1/2y + 1 - 1 = 2 - 1

CANCEL OUT: 1 - 1 because it give you 0

KEEP: 2 - 1 because it help solve for the y-value

NEW EQUATION: 1/2y = 2 - 1

SIMPLIFY IT!
1/2y = 1

MULTIPLY 2 to BOTH SIDES

1/2y * 2 = 1 * 2

CANCEL out: 1/2 * 2 because it give you 1

KEEP: 1 * 2 because it give you the y-value

NEW EQUATION: y = 2 * 1

SIMPLIFY IT!
y = 2

Therefore, your answer is: y = 2

Good luck on your assignment & enjoy your day!

Answer:

1/2y + 1 = 2

1/2y + 1 - 1 = 2 - 1

1 - 1 is equal to 0

2 - 1 help to solve you the y-value

1/2y = 2 - 1

1/2y = 1

1/2y * 2 = 1 * 2

1/2 * 2 it will give you 1

1 * 2 It will give the y-value

y = 2 * 1

y = 2

The answer is

y = 2

Answer:

-1/3

Step-by-step explanation:

Answer:

-0.33

Step-by-step explanation:

The slope is -0.33 bc first, the line is going down so its negative. Second, use rise/run which is the Hight from each point / the length from each of the points. you can see that the rise is one, and the run is three so do 1/3 which equals -0.33

Answer:

216

Step-by-step explanation:

1. Multiply 6 and 6

6 x 6 = 36

2. Multiply 36 and 6

36 x 6 = 216

Answer:

216

Step-by-step explanation:

6³ is basically 6 x 6 x 6

6 x 6 x 6 = 36 x 6 = 216

Hey there!

Answer:

LCM = 72

Solution by Division Method

Write your numbers in the top row.

Divide your numbers by prime numbers as long as at least one of your numbers is evenly divisible by a prime number.

Division Table

2 |8|9

2 |4|9

2 |2|9

3. |1 |9

3 |1|3

| 1 |1

Bring down any numbers that are not evenly divisible by the prime number.

When the last row of results is all 1's you are done.

Find the product of the prime numbers in the first column to get the LCM:

LCM = 2 x 2 x 2 x 3 x 3

LCM = 72

Therefore,

LCM(8, 9) = 72

Answer:

168 degrees

Step-by-step explanation: first you would do (2x-3)+8x so you would have 10x-3 and that equals 180 degrees since its a straight angle. so you would do 10x-3=180 divide by 10, x-3=18 and add 3 so x=21  then since 2 is 8x you would multiply 8 by 21 which is 168.  

Answer:

1/26 or about 3.8%.

Step-by-step explanation:

There are 26 letters in the alphabet, and only one of them is the letter "K". Which means the probability would be 1/26. In percent form, that is about 3.8%.
