how do I solve −2(n− 9) + 4 using distributive property or combining like terms?

Answers

Answer:

Multiply the term outside of the parentheses by each term in the parentheses. To do this, you are essentially distributing the outer term into the inner terms. Multiply the term outside the parentheses by the first term in the parentheses. Then multiply it by the second term. If there are more than two terms, keep distributing the term until there are no terms left. Keep whatever operation (plus or minus) is in the parentheses

Hello!! I need help with square root please help me!!!

Answers

Ok so what you need to do is you need to get all the numbers and see which one is the right number so...

A. y = 11.2 that is wrong

B. y = 25 is wrong

C. y = 5 is right

D. y = 15 is wrong.

C is right because it would be 5 times 5 times 5. SO 5 times 5 is 25, and then u times it by 5 and you get 125!

C is correct

Hope this helps!!

Answer:

This is actually a cube root, since you need a cube root to cancel out the cube.

C, y = 5

Step-by-step explanation:

125 = 5 × 5 × 5 = 5^3

5 × 5 × 5 = 25 × 5 = 125.

Therefore the cube root of 125 = 5.

It REALLY helps when you break these into factors.

[tex] \sqrt[3]{125} = 5 , \: as \: {5}^{3} \: = 125 [/tex]

This is essentially asking what multiplied by itself three times is equal to 125.

Process of elimination can be used for any number cubed that is ≠ 125

i.e : 11.2^3 ≠ 125

11.2^3 = 11.2 × 11.2 × 11.2 = (11.2-1.2)(11.2+1.2)(11.2) = (11.2)((10)(12.4) + 1.2^2) = 124 + 1.44 = (125.44)(11.2) = 125.44(10+1+(2/10)) = 1254.4 + 125.44 + 25.088 = 1404.928 ≠ 125, y ≠ 11.2

I.e : 25^3 = 25 × 25 × 25 = 625 × 25 = (600+25)(25) = 625 + 6(25)(100) = 15000 + 625 = 15625 ≠ 125, y ≠ 25.

And i.e: 15^3 = 15 × 15 × 15 = 225 × 15 = (225)(10+5) = 225(10) + 225(10/2) = 2250 + 2250/2 = 2250 + 1125 = 3375 ≠ 125, y ≠ 15.

Morgan is in the business of manufacturing phones. She pays a cost of $200 per phone produced for materials and labor and also must pay a daily fixed cost of $400 to rent the building and equipment. Make a table of values and then write an equation for C,C, in terms of p,p, representing total cost, in dollars, of producing pp phones in a given day.

Answers

Divide 200 and 400 then bam- your answer is there

A linear equation is an algebraic equation of the form [tex]y=mx+b[/tex]. , where m is the slope and b is the y-intercept.

Total cost represented by equation, [tex]C=200x+400[/tex]

Let number of phones is represented by x .

Since, She pays a cost of $200 per phone produced for materials and labor

For x phones, she will pay = 200x

Since, she also pays daily fixed cost of $400 to rent the building and equipment

Therefore, total cost is represented by equation shown below,

Find the values of x and y.

Please show steps

Answers

x: 90 degrees. y: 43 degrees

We know that x is a right angle. The way we find y is to add 47 + 90 which gives us 137. We also know that a right triangle adds up to 180. So, we subtract 137 from 180. This means that y would be 43 degrees.

Sonya made a resolution to walk 2.5 kilometers a day. On Tuesday she walked 4 times around the running track at the local high school (each lap is 0.4 kilometers.) How many additional kilometers does Sonya need to walk? (HINT: this is a multi-step problem with 2 operations...)

Answers

Answer:

0.9km

Step-by-step explanation:

Given that:

Sonya's resolution = walk 2.5 km daily

Total distance walked on Tuesday = 4 times around a running track

1 lap = 0.4 km

Hence, total distance by walking 4 times around track :

0.4km * 4 = 1.6km

Additional kilometers Sonya needs to walk:

2.5 - 1.6 = 0.9 km

I am selling 900 yearbooks, making a total of $2820. The large yearbook pages cost $4 and the small cost $2.50. Find how many of each I sold. HELPPP PLS

Answers

Answer:

number of large year book sold = 380

number of small year book sold =520

Step-by-step explanation:

Let the no. of large year book pages be x

given that

cost of 1 large year book = $4

cost of x large year book = x*cost of 1 large year book = $4x

Let the no. of small year book pages be y

given that

cost of 1 small year book = $2.5

cost of y small year book = y*cost of 1 large year book = $2.5y

also,

total year books sold were 900

no. of small year book + no. of small year book = 900

x + y = 900

y = 900 - x  ------------------>1

also total money made by selling large and small year book = $2820

cost of x small year book + cost of x large year book = 2820

4x + 2.5y = 2820

using y = 900 - x in above equation

4x + 2.5(900-x) = 2820

4x + 2250 - 2.5x = 2820

1.5x = 2820-2250 = 570

x = 570/1.5 = 380

Thus,

number of large year book sold = 380

number of small year book sold = 900-380 = 520

Square root of 7

Answers

Answer:

7

Step-by-step explanation:

let the other leg be x

Then using Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 3² = 4²

x² + 9 = 16 ( subtract 9 from both sides )

x² = 7 ( take the square root of both sides )

x = 7

Answer:

7

Step-by-step explanation:

let the other leg be x

Then using Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 3² = 4²

5 pencils and 3 pens costs £11.
4 pencils and 6 pens costs £16.
Find the cost of a pencil.
Find the cost of a pen.

Answers

Answer:

The pencil is £1 and the pen is £2

Step-by-step explanation:

Let the pencil be p and let the pen be f.

5p + 3f = 11

4p + 6f = 16

the top one multiplies by two:

10p + 6f = 22

4p + 6f = 16    subtract

6p = £6

pencil = £1

Then you substitute the value of the pencil into the equation and find the value of the pen.
