{30 POINTS!} HELP! Two communications companies offer calling plans. With Company​ X, it costs 35¢ to connect and then 5¢ for each minute. With Company​ Y, it costs 20¢ to connect and then 4¢ for each minute. Write and simplify an expression that represents how much more Company X​ charges, in​ cents, for n minutes
(35+5​n)−​(20+4​n)

Answers

Answer:

(20 + n)¢

Step-by-step explanation:

With Company X, it costs 35¢ to connect  and then 5¢ for each minute.

So, for n minutes of calling the company X charges, C(x) = (35 + 5n)¢

Again,  With Company Y,  it costs 15¢ to connect and then 4¢ for each  minute.

So, for n minutes of calling the company Y charges, C(y) = (15 + 4n)¢.

Therefore, the company Y charges for n minutes of calling less than company X is [(35 + 5n) - (15 + 4n)]¢ = (20 + n)¢ (Answer)

correct answer- (20+n) cent sign

The variables x and y have a proportional relationship, and y= 5/6 which equation represents this relationship? x= 3/4. Which equation represents this relationship?

Answers

Answer:

(d)  y= (1 1/9)x

Step-by-step explanation:

A proportional relation is described by the equation ...

 y = kx

Dividing by x shows how to find the value of k:

 k = y/x

For the given values of y and x, the value of k is found to be ...

 k = (5/6)/(3/4) = (5/6)(4/3) = 20/18 = 10/9 = 1 1/9

The relationship is represented by the equation ...

 y = (1 1/9)

Jasmine picked 2/5 of a bucket of strawberries. Her friend picked 3/4 of the amount Jasmine picked. How much
of a bucket of strawberries did Jasmine's friend pick?

Answers

Answer:

If Jasmine picked 4/10 (which is equivalent to 2/5) then that would mean Jasmine's friend picked 3/10.

If Jasmine picked 4 berries out of 10, that means Jasmines friend picked 3 berries out of ten.

Step-by-step explanation:

2/5 x 4 = 8/20

8/20 x 5 = 40/100

three quarters of 40/100 is 30/100

if you divide 3/4 from 2/5, you get 8/15
