Use the distributive property to write an equivalent expression without parentheses. The problem has been started for you below. 4 (n + 5) = 4 (n) + 4 (5) Which expression is equivalent to 4(n + 5)? 4n 24n 4n + 9 4n + 20

Answers

Answer 1

Answer:

4(n + 5) = 4n+20

Step-by-step explanation:

We need to find the equivalent expression to 4(n + 5). It can be done using the distributive property as follows :

a(b+c) = ab + ac

Here, a = 4, b = n and c = 5

4(n + 5) = 4n + (4)(5)

= 4n+20

So, the equivalent expression is 4n+20.

Answer 2

Answer:

The answer is 4n+20 aka D

Answer:

1) volume = 102.92 m²

2a) Perimeter = 28 inches

2b) Actual perimeter = 672 inches or 56 feet

2c) Exactly 24 times greater

Step-by-step explanation:

1)

4x5.5 = 22

full circle = (5.5²)(π) = 95

(30/360)(95) = 7.92

95+7.92 = 102.92 m²

2a)

Perimeter = (2)(6+8) = 28 inches

2b)

Actual perimeter = (2)(144+192) = 672 inches or 56 feet

2c)

(24)(28) = (2)(144+192)

672 = 672

Exactly 24 times greater

A regular pentagon with sides each measuring 6 inches is dilated by a scale factor of 3.1. What is the length of each side of the dilated pentagon?

Answers

Answer:

18.6inches

Step-by-step explanation:

Given the length of a side of a pentagon to be 6 inches.

If this length is dilated by a factor of 3.1, the new length will be;

New length = Old length * dilation factor

New length = 6 * 3.1

New length = 18.6inches

Hence the length of each side of the dilated pentagon is 18.6inches

I am confused

Answers

Answer:

Step-by-step explanation:

A line is expressed as y=mx+b where m=slope and b=y intercept. As long as we have two points we can solve the equation of that line.

y=mx+b

For the top line I found two points (5,200) and (30,325)

m=(y2-y1)/(x2-x1)=(325-200)/(30-5)=125/25=5

y=5x+b, using point (5,200) we can solve for b

200=5(5)+b, b=200-25=175 so the line is

y=5x+175

For the bottom line we have points (5,50) and 10,100)

m=(100-50)/(10-5)=50/5=10

y=10x+b, using point (5,50) we have

50=10(5)+b, b=50-50=0 so

y=10x

In a department store a $40 dress is marked save 25%.You also pay a 7% sales tax. What is the sale price of the dress?

Answers

Answer:

$32.1

Step-by-step explanation:

First find out what 25% of 40 is:

$40 x .25 = $10

Take the answer and subtract that from the original price:

$40 - $10 = $30

Next, take the sales tax (7% or 0.07) and multiply that by the new price:

$30 x 0.07 = $2.1

Lastly, take the answer and add that to the new price:

$30 + $2.1 = $32.1

Then you would get your answer:

$32.1

Answer:

x = 14°

Step-by-step explanation:

We can see that these angles are supplementary.

Set up an equation

x + 96 + 5x = 180

6x + 96 = 180

subtract 96 from both sides

6x = 84

x = 14

A shop sells fruit in two types of gift boxes: standard and deluxe. Each standard box contained 1kg of peaches and 2kg of apples and each deluxe box contains 2kg of peaches and 1.5 kg of apples. On one particular day the shop sold 12kg of peaches and 14kg of apples in gift boxes. How many containers of each kind of box were sold on the day?

Answers

Let's call the number of standard boxes sold x and the number of deluxe boxes sold y.
The kg of peaches sold will be 1 for each standard box and 2 for each deluxe, so we know:
x + 2y = 12
The kg of apples sold will be 2 for each standard box and 1.5 for each deluxe, so:
2x + 1.5y = 14. Now we solve the two equations as a system:
From the 1st one:
x = 12 - 2y
We substitute in the second one:
2(12 - 2y) +1.5y = 14;
24 - 4y +1.5y = 14;
-2.5y = -10;
y = 10/2.5 = 4;
Now we substitute in the first equation:
x = 12 - 2y = 12 - 2*4 = 12 - 8 = 4.
So the shop sold 4 standard boxes (x) and 4 deluxe boxes (y).

4x-55 would be what’s ced
Bec 4x-5

Answer:

x=11°

<Bec = 33°

<Ced = 39°

Step-by-step explanation:

That's a right angle so it would be 90 degrees angle.

18+3x+4x-5=90

Lets simplify it to make it easier to work out by collecting like terms.

First all the variable 3x+4x=7x

Then the numbers 18+-5=13

13(-13)+7x = 90(-13)take away 13 from both sides

(Opposite operators EG, Add becomes subtract)

7x = 77 then divide 7 from both sides

x=11

Then work out

3x11=33 degrees

4x11=44-5=39 degrees

To double check 39+33+18=90 degrees
