K = -3

1. Simplify -k-4k to -5k

-5k=3(k-10)-6(k-6)

2. Distribute Parentheses/Expand

-5k=3k-30-6k+36

3.Simplify 3k-30-6k+36 to -3k +6

-5k=-3k+6

4. Add 3k to both sides

-5k+3k=6

5. Simplify -5k+3k to -2k

-2k=6

6. Divide both sides by -2

Hey there! I'm happy to help!

When multiplying numbers with exponents, you add the numbers in the exponent. So, [tex]4^2+4^8=4^1^0[/tex]. If you plug this into your calculator, you get 1048576, which is [tex]4^1^0[/tex].

Have a wonderful day! :D

Answer:

4^10/ 4 to the 10th power

Step-by-step explanation:

Answer: Thursday

Explanation: its Thursday because Monday is 5° below 0 is a negative number and Wednesday is 2° below 0 is also a negative number because its below 0. Now on Thursday its 3° above 0 which is the correct answer you need because its above the negative numbers of 0 which = a positive number now Tuesday is 0° which is just 0 nothing else.

.Start: 48 cookies

Son ate ¼ = 12

36 cookies remain at this point.

Husband ate one sixth ; that's 6 cookies for him, 30 remain.

Answer:

Mrs. Jones has 30 cookies left.

Step-by-step explanation:

First you divide 48 by 4, you then subtract that from 48, so 48-12= 36. next you divide that by six, which is 6, 36-6=30.

Answer:

the batter have hits 754

Step-by-step explanation:

given:

If a batter has a batting average of 265 and has been at bat

200 times

find:

how many hits does the batter have?

batting average = 265 / 100 = 0.265

number of bat times = 200

let hits = h

aver = bat times

           no. of hits

0.265 =  200 bat times

                    h

cross multiply:

0.265 h = 200

h = 200 / 0.265

h ≅ 754.72

therefore,

the batter have hits 754

Answer:

hits = 754

Step-by-step explanation:

If a batter has a batting average of 265 and has been at bat  

200 times

batting average =  0.265

number of bat times = 200

aver = bat / h

0.265 =  200 / h              

0.265 h = 200

h = 200 / 0.265

h ≅ 754.72

Given:

Side lengths of triangle are (6.2v-5.5) cm, (8.5v-6.7) cm, and (6.6w+7.6) cm.

To find:

The expression which represents the perimeter of the given triangle.

Solution:

We know that perimeter of a triangle is the sum of all sides of a triangle. So,

[tex]Perimeter=(6.2v-5.5)+(8.5v-6.7)+(6.6w+7.6)[/tex]

On combining like terms, we get

[tex]Perimeter=(6.2v+8.5v)+6.6w+(-5.5-6.7+7.6)[/tex]

[tex]Perimeter=14.7v+6.6w+(-4.6)[/tex]

[tex]Perimeter=14.7v+6.6w-4.6[/tex]

Therefore, the perimeter of the triangle is [tex]14.7v+6.6w-4.6[/tex].

The two binomials for the expression x(x − 8) − 9(x − 8) are (x - 8) and (x - 9).

What are the binomials expression ?

The expression x(x − 8) − 9(x − 8) can be simplified as follows:

x(x − 8) − 9(x − 8) = x² - 8x - 9x + 72

= x² - 17x + 72

To find the two binomials, we need to factor the expression [tex]x^2 - 17x + 72[/tex]. We can do this by finding two numbers that multiply to 72 and add to -17. Those numbers are -8 and -9. Therefore, we can write:

[tex]x^2 - 17x + 72 = (x - 8)(x - 9)[/tex]

Hence, the two binomials for the expression x(x − 8) − 9(x − 8) are (x - 8) and (x - 9).

Scale using for plan ⇒ 1 m = 4 cm

Step-by-step explanation:

Given:

Actual length of wall = 4 m

Segment of wall = 16 cm long

Find:

Scale using for plan

Computation:

Actual length of wall = Segment of wall

4 m = 16 cm

1 m = 16 / 4 cm

1 m = 4 cm

Scale using for plan ⇒ 1 m = 4 cm

Answer:

Step-by-step explanation: it’s 1 m because it’s equal to 4

Answer:

The three integers are

11, 13, and 15.

Step-by-step explanation:

We shall consider the integers as

x, (x+2), and (x+4). The sum of these is 39, so we can write:

x+(x+2)+(x+4)=39

Open the brackets and simplify.

x+x+2+x+4=39 3x+6=39 Subtract 6 from each side.3x=33 Divide both sides by 3.x=11 Therefore: (x+2)=13and (x+4)=15

Answer:

The three integers are 11, 13, and 15 .

Step-by-step explanation:

We shall consider the integers as x, ( x + 2 ) , and ( x + 4 ) . The sum of these is 39, so we can write:

x + (x + 2) + (x + 4) = 39

Open the brackets and simplify.

x + x + 2 + x + 4 = 39

3x + 6 = 39

Subtract 6 from each side.

3x = 33

Divide both sides by 3.

x=11

Therefore: (x + 2) = 13 and (x + 4) = 15

Answer:

irrational numbers and real numbers

Step-by-step explanation:

The question is incomplete. Here is the complete question.

Tell which set or sets does the number 8/9 belong to: natural numbers, whole numbers, integers, rational numbers, irrational numbers, or real numbers?

Natural numbers are positive whole numbers and they start from 1. Negative numbers and zero are not natural numbers. Example of natural numbers are 1,2, 3, 4... and since 8/9 is a fraction, hence it is not a natural number.

8/9 is not also a whole number. Whole numbers are not written as fractions.

Integers are both positive and negative whole numbers including zero. They are not expressed as ratio of two whole numbers. They are not fractions as well hence 8/9 is not an integer.

Real numbers are both rational numbers and irrational numbers. They can be expressed as a ratio of two integers and can be expressed as decimal. Hence 8/9 is a real number and also irrational numbers.

An irrational number when written as decimal, the number after the decimal does not terminate.

8/9 = 0.888888888888...

As we can see, the number 8 after the decimal point is infinite, hence the reason why 8/9 is an irrational number
