First find the lowest common multiple of the denominators which are 12 3 9 and 27 these all go into 108. Next divide 108 by the original denominators for example 108/12 is 9 then times 9 by the numerator which is 5 and you get 45 so the first one is 45/108. Do this for them all and order by the size of the numerator

A phone company offers two monthly plans. Plan A costs $19 plus an additional $0.11 for each minute of calls. Plan B costs $10 p

Aloiza [94]

Answer:

Part 1) When the amount of calling is 450 minutes the two plans cost the same

Part 2) When the two plans cost the same , the cost is $68.50

Step-by-step explanation:

Part 1) For what amount of calling do the two plans cost the same?

Let

x ---> the number of minutes

y ----> the total cost

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value

In this problem we have

Plan A

The slope is equal to

$m=\$0.11\ per\ minute$

The y-intercept is

$b=\$19$

substitute

$y=0.11x+19$ ----> equation A

Plan B

The slope is equal to

$m=\$0.13\ per\ minute$

The y-intercept is

$b=\$10$

substitute

$y=0.13x+10$ ----> equation B

Equate equation A and equation B

$0.13x+10=0.11x+19$

solve for x

$0.13x-0.11x=19-10\\0.02x=9\\x=450$

therefore

When the amount of calling is 450 minutes the two plans cost the same

Part 2) What is the cost when the two plans cost the same?

substitute the value of x=450 minutes in equation A or equation B and solve for y

$y=0.11(450)+19=68.5$

therefore

When the two plans cost the same , the cost is $68.50

The sum of two numbers exceeds their product by one.Their difference is equal to their products less five .Find the two numbers

Ludmilka [50]

Answer:

1 and 3

Step-by-step explanation:

If the two numbers are x and y, then:

x + y = xy + 1

x − y = xy − 5

Subtract the two equations:

(x + y) − (x − y) = (xy + 1) − (xy − 5)

x + y − x + y = xy + 1 − xy + 5

2y = 6

y = 3

Solve for x:

x + 3 = 3x + 1

2 = 2x

x = 1

The numbers are 1 and 3.
