3(5 - 2n) + 9n simplified is?

Answer:

0.16/8.5

Step-by-step explanation:

so to get the slope use (Y2-Y1) over (X2-X1)

this means that the formula is

1/2-1/3

---------

25.5- 17

Answer:

8/12

Step-by-step explanation:

you want to write out your problem so it is

1/4 * 2 2/3

then you would want to change your 2nd fraction into an improper fraction (i think.  i don't remember the correct term)

so you would multiply the denominator by the whole number on the side and then add the numerator to it

2 2/3 would them become 8/3 (you keep the denominator the same through the process)

so then you would multiply

1/4 by 8/3

multiply across and you get 8/12

Im not a very good explainer but i hope i helped :)

Answer:

the first choice, the third, and the fourth

The inequality which is equal to r>-11 is -3r<33.

Inequality is like an equation but it is expressed in greater than ,less than ,greater than or equal to and less than or equal to form. It also shows a relationship between two or more variables. We can also change sign by putting negative sign in both sides of the sign.

We have been given inequality as r>-11 and we have to find the appropriate equivalent inequality from the given options.

We can find the inequality by multiplying and changing sign by putting negative sign on both sides of sign.

r>-11

Multiply both sides by 3

3*r>-11*3

3r>-33

Change > sign to < sign.

-3r<-(-33)

-3r<33

Hence the inequality which is equal to r>-11 is -3r<33.

Answer:

k = -5

g = 6

Step-by-step explanation

1) First solve for k and plug that into the other equation to solve for g.

5g + 4k = 10

4k = -5g + 10

k = -5/4g + 2.5

2) Plug k into the other equation to solve for g

-3g - 5k = 7

-3g = 5k + 7

-3g = 5(-5/4g + 2.5) + 7         Use the distributive property

-3g = -6.25g + 12.5 + 7        Combine like terms and simplify

-3g = -6.25g + 19.5               Add 6.25g to both sides

3.25g = 19.5                          Divide 3.25 from both sides to find g

g = 6

3) Now we take this g and plug it into the other equation to find k

(we could also just plug it into this equation as well)

5g + 4k = 10

5(6) + 4k = 10

30 + 4k = 10

4k = -20

k = -5.

If we really wanted to doube check this then we could plug the k value into the equation we used to find the g value...

-3(6) - 5(-5) = 7

-18 + 25 = 7

So yes, k = -5 and g = 6.

Answer:

d

Step-by-step explanation:

the answer is d cause you can get it later if you know what I mean

Answer:

3

My logic:

so she jars 10 on the first day (that is 1 day) and she wants to jar 16. so if you subtract 10 from 16 you get 6. Now we know she wants to jar 6 more, and if she does 3 every day then you would divide 6 by 3 and get 2. 2+1 is 3, so 3 days. (if you cant chose 3 chose 2 because your teacher might not want yo to count the first day)

Answer:

it would be 1385

Step-by-step explanation: because 850 miles per hour converted into meter per min would be 22799.04 meters per sec and then u would Find the number in the whole number place 4 and look one place to the right for the rounding digit on the right side of the decimal point 7. Round up if this number is greater than or equal to 5 and round down if it is less than 5

So the answer is 1385

Answer:

22799 meters per minute I don't know how to express

multiply 850 by 26.822 and u should get 22799 well almost

Question:

12x-5y=-20

y=x+4

1) Simplify the first equation!

12x-5y=-20

Move 12x to the other side (remember when you move numbers to the opposite side of the equation, it makes them negative) to isolate y!

-5y=-20-12x

Divide all numbers by -5 to just get the variable y

y=4+12/5x

2) Solve

I'm going to be solving by substitution since I like this method the best!

y=4+12/5x

y=x+4

1) Set the equations equal to another (you'll be replacing the variable of y for an equation)

x+4 will be replacing y of the other equation

x+4 = 4+12/5x

2) Simplify

Subtract x on both sides

x-x + 4 = 4+ 12/5x-x

4=4+7/5x

Subtract 4 on both sides

0=7/5x

x is equal to 0!

3) Find y

1) Set x equal to 0 in an equation (I'm doing y=x+4 because it's easier!)

y=x+4

y=0+4

2) Simplify

y=4

12 goes into 276, 23 times

Answer: 240 days.

Step-by-step explanation:

The number of days that it'll will be until all the computers run a virus scan at the same time again will be calculated by solving for the lowest common multiples of the numbers. This will be:

Multiples of 10 = 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240.

Multiples of 12 = 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180, 192, 204, 216, 228, 240

Multiples of 16 = 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176, 192, 208, 224, 240

Here, we can see that the least common multiple is 240. Therefore, all the computers will scan at the same time in 240 days.

Answer:

32 pounds

Step-by-step explanation:

$3 flat fee for a package, plus a fee based on the weight of the package. The company charges $0.75 per pound, plus an additional $0.50 for every pound over 12 pounds.

The first step would be to derived an equation

$3 + $0.75

3 + 0.75x

Where x = number of pounds

George plans on sending a package that is over 12 pounds. He has $27 to spend on shipping.

Hence,

3 + 0.75x = 27

0.75x + 3 = 27

0.75x = 27 - 3

0.75x = 24

x = 24/0.75

x = 32 pounds

The maximum number of pounds that this package could be is 32 pounds

Answer:

x>-1

Step-by-step explanation:

first, you have to distribute. 12x+8-6>2x-16+8

then you have to combine like terms 12x+2>2x-8

you put the X's on one side 10x+2> -8

move the 2 to the -8 10x>-10

divide x>-1

Answer:

Number 2. x>-1

Step-by-step explanation:

4(3x+2) is 12x+8. 12x+8-6 is 12x+2.

12x+2>8+2(x-8)

2(x-8) is 2x-16. 2x-16+8 is 2x-8.

12x+2>2x-8

12x>2x-10

10x>-10

x>-1

Answer:

Answer:

the slope is [tex]\frac{7}{4}[/tex]

Step-by-step explanation:

Given: 4y - 7x = 10; solve y

4y - 7x = 10; add 7x to both sides to isolate the 4y variable

4y = 7x + 10; now divide by 4

y = [tex]\frac{7}{4}[/tex]x + [tex]\frac{10}{4}[/tex]; reduce the fraction

y = [tex]\frac{7}{4}[/tex]x + [tex]\frac{5}{2}[/tex]; the slope is
