Answer: 7x+y+8

Step-by-step explanation:

Combining like terms is just like what it sounds. You take the like terms, or terms that have the same variables and such, and add them together.

For this problem, we can see that 12x and -5x are like terms because they both consist of a numerical coefficient and the variable x.

We can see that -3y and 4y are like terms because they both have a numerical coefficient and y for variable.

Now, we can combine like terms.

12x-3y+8-5x+4y                     [combine like terms]

7x+y+8

Answer: The range in golf scores was 14.

Step-by-step explanation:

Range = Maximum - minimum

Values above some limit are represented by positive integers whereas values blow a certain limit is represented by negative numbers.

Given: The golfer with the highest score in a tournament was nine over par i.e. (9). The golfer with the lowest was five below par i.e. (-5 ).

So, the range in golf scores =  9-(-5)

=  9+5

= 14

Therefore, the range in golf scores was 14.

2 pages/min

Step-by-step explanation:

Unit rate is:

  1/5 page        1 * 10

------------------ = --------- page/min = 2 pages/min

 1/10 min           5 * 1

Answer:

30 seconds

Step-by-step explanation:

1/10 of a minute: 6 seconds

60/10 = 6

6x10 = 60

now, if 6 seconds is 1/5 of the page you need to multiply

6 x 5 = 30 seconds

it takes him 30 seconds to write a page

Answer:

The domain of a function is the set of numbers for which the function is defined.

Here, this function has values of number from -1 to +3

therefore, it's domain is [-1,3]

The range is the set of results of a function

here, this function ranges between -5 to +4

therefore, its range is [-5,4]

Answer:

(4v + 3) and (v - 7)

Step-by-step explanation:

First rewrite 4v2 - 25v = 21 as 4v^2 - 25v - 21.

Let's now analyze -25v and -21.  We need to identify two integers whose product is 21 and whose sum is -25.  

Note that factors of -21 are ±1, ±3, ±7 and ±21.  Factors of 4 (the coefficient of v^2) are ±1, ±2 and ±4.

Check out the following trial factors:   (4v + 3) and (v - 7).  Does this product come out to the given 4v^2 - 25v - 21?  Yes.   So the desired factors of 4v2 - 25v = 21 are (4v + 3) and (v - 7).  Note how (3)(-7) = -21 and how 4(-7) + 3v add up to -25, the coefficient of the v term.

Answer:

y = 5

Step-by-step explanation:

We khow that x and y are consecutive integers and that x^2 is greater than y^2 since x^2-y^2=11

● so x is greater than y

● wich means that x = y+1

● x^2-y^2=11

● (y+1)^2-y^2 = 11

● y^2+2y+1-y^2=11

● 2y + 1 = 11

● 2y +1-1 = 11-1

● 2y = 10

●2y/2 = 10/2

● y = 5

Answer:

10in pizza

Step-by-step explanation:

We need to find the area of each pizza.

A = [tex]\pi[/tex][tex]r^{2}[/tex]

radius is 1/2 the diameter.

1in pizza                                    10in pizza

A = [tex]\pi[/tex]([tex].5^{2}[/tex])                                    A = [tex]\pi (2.5^{2} )[/tex]

A = .25[tex]\pi[/tex]                                     A = 6.25[tex]\pi[/tex]

A = .79                                        A = 19.63

                                                   19.63/10 for [tex]in^{2}[/tex] per $1

So the 1in pizza bite is $1 for .79[tex]in^{2}[/tex]  and we can see from the 10in pizza it's $1 for 1.96[tex]in^{2}[/tex]. So it is much better to get the 10in pizza.

Answer: -5x^3 + 5y^3

Step-by-step explanation: The other parts cancelled out

Answer:

= -5x³ + 5y³

Step-by-step explanation:

4y³ - 5x³ - 1 - 4y³ - 6 + 7 + 5y³

= -5x³ + (4y³ - 4y³ + 5y³) + (- 1 - 6 + 7)

= -5x³ + (0 + 5y³) + (- 7 + 7)

= -5x³ + 5y³

Answer: A) Whole number

Explanation:

The set of whole numbers is {0,1,2,3,...} showing that negative values are not in this set. A distance below sea level is written as a negative (where positive values are above sea level). So you won't use the set of whole numbers for this type of problem.

In contrast, something like the set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ... } including negatives this time. For example, we can write -10 to indicate we're 10 feet below sea level. Rational numbers and real numbers can also be negative.

Answer:

[tex]-(202x+5)[/tex] is the equivalent expression

Step-by-step explanation:

Given the following expression

[tex]12x+(-7)-214x-(-2)[/tex]

We are expected to find and re-write the expression such that it equals the given expression

We proceed by opening all brackets and work operations on signs

[tex]12x-7-214x+2[/tex]

collecting like terms we have

[tex]12x-214x-7+2\\\\-202x-5[/tex]

Answer:

2:06

Step-by-step explanation:

You just need to find the Least Common Multiple of the 3 numbers. In this case it was 126 which if those are minutes that would mean 2 hours and 6 minutes.

Answer:

angle 1 and 3 are equal by vertically opp. angle

3x-1 = 2x +9

3x-2x = 9+1

x = 10

put the value of x in any equation

3(10)-1 = 29

angle 1 = angle 3 = 29

angle 2 + angle 3 = 180 ° (linear pair)

angle 2 = 180 -29

angle 2 = 149

angle = angle 3 = 149.

Answer:

When we are multiplying the same number, let it be n, m times, what we do is:

[tex]n^m[/tex], where n is the base and m the exponent.

In this case we have 4 fives, 2 threes, 3 x and 1 y which are being multiplied , so we can convert them to exponents:

Then we multiply all: [tex]5^4*3^2*x^3y[/tex]

Answer: [-5,∞)

Step-by-step explanation:

z-18 ≥ -23     Add 18  to both sides

 +18   +18

z ≥ -5    

Which means x has to be greater than negative 5.

In interval notation it will be [-5,∞)

Answer:

z ∈ [-5; +∞)

Step-by-step explanation:

z - 18 ≥ - 23

<=> z ≥ 18 - 23

<=> z ≥ -5

----> z ∈ [-5; +∞)

Answer:

34

Step-by-step explanation:

There are 34 people in the garden prior to the time I joined them.

So when I entered the garden, the total number of people in the garden will be:

Let assume, you as the reader was part of the people in the garden and you hugged 30 people. That doesn't add up or increase the number of people in the garden.

At the end of the day, the number of people you did not hug is:

35 - 30 - 1(you)

= 35 - 31

= 4 people

Therefore, we can conclude that there are 35 people present in the garden.

Answer/

Step-by-step explanation:

Look at the powers of each x10. The bigger the power, the bigger the mass. Of two are in the same order, you look at the number next to it.

The ascending order from least to greatest is

Atmosphere - 5.1 × 10¹⁸ kg

Oceans - 1.4 × 10²¹ kg

Inner core - 9.675 × 10²² kg

Crust - 2.6 × 10²² kg

Outer core - 1.835 × 10²⁴ kg

When numbers are arranged in ascending order, they are done so from least to largest. We must first compare the numbers before we may arrange them in any order. Compare first, then order. Numbers arranged in ascending order: Determine how many digits each number has.

Given data ,

Let the masses of each part of the Earth be

oceans     1.4 × 1021kg

crust      2.6 × 1022kg

atmosphere   5.1 × 1018kg

mantle     4.043 × 1024kg

outer core   1.835 × 1024kg

inner core   9.675 × 1022kg

And , arranging them in ascending order , we get

Atmosphere - 5.1 × 10¹⁸ kg

Oceans - 1.4 × 10²¹ kg

Inner core - 9.675 × 10²² kg

Crust - 2.6 × 10²² kg

Outer core - 1.835 × 10²⁴ kg

Hence , the arranging order is solved
