-27 is an integer

It's not a whole number because a whole number is all POSITIVE whole numbers and ZERO.

It could be rational number but integer is more specific, so the answer is A. integer

Answer:

x = 8

Step-by-step explanation:

first you’ll want to do 4/7 times 21 (a number or fraction in front of a parenthesis without a “+” or ”-“ sign must be multiplied) which is 12, then you add 12+5 to get 17. Next you subtract 17 from 41 to get 24, then you will divide 24 by 3x to get 8 = x.

Answer: 68 degrees

Step-by-step explanation:

First, expand the bracket

2.1s + 2.8 - 1.1s = 7.9

Next, collect like terms

s + 2.8 = 7.9

Lastly subtract 2.8 from 7.9 to get your answer.

s = 5.1

(Hope this helps! ^^)

Answer:

[tex]\boxed {s = 5.1}[/tex]

Step-by-step explanation:

Solve for the value of [tex]s[/tex]:

[tex]0.7(3s + 4) - 1.1s = 7.9[/tex]

-Use Distributive Property:

[tex]0.7(3s + 4) - 1.1s = 7.9[/tex]

[tex]2.1s + 2.8 - 1.1s = 7.9[/tex]

-Combine like terms:

[tex]2.1s + 2.8 - 1.1s = 7.9[/tex]

[tex]s + 2.8 = 7.9[/tex]

-Subtract [tex]2.8[/tex] to both sides:

[tex]s + 2.8 - 2.8 = 7.9 - 2.8[/tex]

[tex]\boxed {s = 5.1}[/tex]

So, the value of [tex]x[/tex] is [tex]5.1[/tex].

Answer:

a: K = 2s

K + s = 42

b: 2s + s = 42

K = 28

s = 14

Step-by-step explanation:

1. Come up with equations based on the information given.

K = Kim

s = sister

Kim is twice of her sister -> K = 2s

When you add Kim's age to her sister's age, you get 42 -> K + s = 42

2. Substitue for K to find out the value of s

K = 2s

2s + s = 42

3. Solve for s

s = 42/3

s= 14

4. Solve for K

K = 2s

K = 2*14

K = 28

Answer:

12:176 or 12/176

Step-by-step explanation:

Multiply both the top and bottom by 2.

6/88. 6 x 2= 12. 88 x 2= 176

So, 6:88 = 12:176 because you multiplied both numbers by 2.

6/88 x 2/2 = 12/176

Answer:

  16 points

Step-by-step explanation:

You are given ...

  second = first - 4

  second = 12

Substituting the second equation into the first, we have ...

  12 = first - 4

  16 = first . . . . . . . . add 4 to both sides

Answer:

x = 20

Step-by-step explanation:

62 = (2+3x)

You want to isolate x, so first you subtract 2 from each side

60 = 3x

Now, you divide each side by 3

20 = x

There's your answer!

5x+5+65+65=

Answer:

x=-27

Step-by-step explanation:

We want to find x right, so everything that does not have x you can move to the other side. 5x=-5-65-65. So that should be your equation so far. Now we know that when there are two negatives it is a negative and you add so -5-65=-70-65=-135. So your equation now should be: 5x=-135. Now we can divide -135 with 5 which gives us... -27! There’s your answer. Hope this was correct!

Answer:

The hourly drop between the two times is 1/40

Step-by-step explanation:

Firstly, we need to find the difference in time between 9 pm and 6:36 am

That would be 9 hours and 36 minutes

It would be needed to convert 36 minutes to hours

Mathematically, 60 minutes = 1 hour

So 36 minutes = (36 * 1)/60 = 36/60 = 0.6

So the difference between the two time is simple 9.6 hours

So the total drop during the time is given by 6/25

So the hourly drop will be 6/25 divided by 9.6

= 6/25 * 1/9.6 = 6/240 = 1/40

Answer:

8: C

9: D

10: C

11: D

Step-by-step explanation:

On number 8, the pattern is by starting from 3, and squaring it. Then you take that square and square it again. So 3 squared is 9, and then you square 9 which is 9 times 9 giving you 81. Then you square 81 giving you 6561.

9: Negative exponents work by flipping the number upside down, and then doing normal exponential work on the now denominator.

If the number is 5 to the power of -3, you are flipping 5 to 1/5 and then doing 5 to the power of 3 which is 5x5x5 giving you 125. Therefore the answer would be 1/125.

10 is the same thing as number 9 except backwards, so you flip 1/2^3 to 2^-3

11 is similar, except you have 3.471 times 1/10000

So you add 4 zeros in front of the 3.471 turning it into 0.0003471

Y=3/5

First, set it up so they cancel. I recommend multiplying the second equation by 2, getting

[tex]4x-10y=-3[/tex]

[tex]24x+10y=24[/tex]

add them together, and you get

[tex]28x=21[/tex]

so

[tex]x=3/4[/tex]

then, you plug x into one of the equations (first because it's easier) and get

[tex]3-10y=-3[/tex]

so

[tex]-10y=-6[/tex]

and

[tex]y=3/5[/tex]

Answer:

6x + 14

Step-by-step explanation:

Original Equation:

2x^3 + 1x^2 - 3x + 14

2x to the 3rd power is 8x

8x + 1x^2 - 3x + 14

1x to the 2nd power is 1x

8x + 1x - 3x + 14

8x + 1x = 9x

9x - 3x + 14

9x - 3x = 6x

6x + 14
