Step-by-step explanation:

x-3x-(-5x)=-2x+5x=3x

Answer 2

Answer:

D

Step-by-step explanation:

[tex]x-3x-(-5x)[/tex]

it will be easier to solve the equation in sections:

[tex]x-3x[/tex]

[tex]-2x[/tex]

now deal with the other part

[tex]-(-5x)[/tex]

a negative multiplied by a negative equals a positive so:

[tex]+5x[/tex]

now putting the parts together:

[tex]-2x+5x[/tex]

[tex]3x[/tex], therefore the answer is d: [tex]3x[/tex]

Nathan is making chocolate chip cookies, the recipe calls for 2 cup chocolate chips and will make 4 dozen cookies. He increases the recipe to make 6 dozen cookies and will need 3 cups chocolate chips. Find the constant of proportionality

Answers

Answer:

1/2

Step-by-step explanation:

Nathan is making chocolate chip cookies, the recipe calls for 2 cup chocolate chips and will make 4 dozen cookies. He increases the recipe to make 6 dozen cookies and will need 3 cups chocolate chips. Find the constant of proportionality

From the above question, we can see that the Number of Chocolate chips is directly proportional to the number of Dozen cookies

Hence:

C = Chocolate chips

D = Dozen cookies

Hence:

C ∝ D

C = kD

Where k = Constant of Proportionality.

We are told that , the recipe calls for 2 cup chocolate chips and will make 4 dozen cookies.

Hence:

2 = 4k

k = 2/4

k = 1/2

Also, He increases the recipe to make 6 dozen cookies and will need 3 cups chocolate chips.

3 = 6k

k = 3/6

k = 1/2

Therefore, from the calculations above, the constant of proportionality is 1/2

If the circumference of a circle is 82p , then the value of ‘r’ is

(i) 41 cm
(ii) 82 cm
(iii) 21 cm
(iv) 20 cm​

Answers

Answer:

41cm

Step-by-step explanation:

The circumference of a circle is 82π

Therefore r can be calculated as follows

2 × π × r= 82× π

2πr= 82π

r = 82π/2π

r= 41

Hence r is 41cm

In a fruit punch you mix 150 ml of lemonade with 250 ml of fruit juice. Write the ratio of the volume of lemonade to the volume of fruit juice. Give your ratio in its simplest form.

Answers

Answer:the ratio of the volume of lemonade to the volume of fruit juice in simplest form = 3:5

Step-by-step explanation:

Volume of lemonade in the mixture = 150ml

Volume of fruit juice in the mixture = 250ml

Ratio of the volume of lemonade to the volume of fruit juice= 150ml: 250ml

and reducing to the simplest form , we have

150:250

dividing both by 10 gives

15:25

dividing both by 5 gives

3:5

Therefore  the ratio of the volume of lemonade to the volume of fruit juice in simplest form = 3:5

The grocery store had 4lb bag of oranges for 4.80$ and a 6lb bag for 6.18$ . What is the difference of the 4lb bag of oranges and the 6lb bag of oranges

Answers

Answer:

$1.38

Step-by-step explanation:

The grocery store had 4lb bag of oranges for 4.80$ and a 6lb bag for 6.18$ . What is the difference of the 4lb bag of oranges and the 6lb bag of oranges

The cost difference is calculated as:

Cost of 6lbs of oranges - Cost of 4lbs of oranges

Cost of 6lbs of oranges = $6.18

Cost of 4lbs of oranges = $4.80

Hence,

= $6.18 - $4.80

= $1.38

Of the 10 clients who had their hair cut at Sue's salon last month, 5 had blond hair. Considering this data, how many of the next 14 clients to get haircuts should you expect to have blond hair?

Answers

Answer: 7 clients

Step-by-step explanation:

Of the last 10 clients that cut their hair at the salon, 5 had blond hair.

That is a proportion of:

= 5 / 10

= 1/2

Assuming this same proportion applies to the next clients Sue gets, the expected number of blonde people will be:

= Number of clients * 1/2

= 14 * 1/2

= 7 clients
