You have to use the reciprocal. for example, 4/5 divided by 1/3
you would leave the dividend the same but flip the divisor. you would change it to a multiplication sign. 4/5 times 3/1
then multiply straight across. hope i helped

Hi!

Let's say that we have 5/8 and 3/4 and we have to divide them . One thing that is very important when dividing fractions is knowing the meaning of reciprocal.
When we are dividing fractions we use the reciprocal, for example the reciprocal of 3/4 is 4/3 .

5/8 divided by 3/4 = 5/8 divided by 4/3

Now that we have the reciprocal of 3/4 , we multiply both fractions . We don't "divide them " .
So it's something like this

5/8 times 4/3=20/24

Just find the reciprocal and multiply !

Hope it helps and have a wonderful day!

Find the initial value of the linear function. y = 4x + 3

murzikaleks [220]

Answer:

y = 3

x = -3/4

Step-by-step explanation:

To get the initial value, we will make:

x = 0

y = 0

Then solve for the corresponding value of either x and y

Okay then, from the expression

y = 4x + 3

When x=0

y = 4 (0) + 3

y = 0 + 3

y = 3

When y=0

y = 4x + 3

0 = 4x + 3

4x = -3

x = -3/4

The initial value of the Linear function =

y = 3

x = -3/4

A rental car agency charges $12 per day plus 14 cents per mile to rent a certain car. Another agency charges $15

Sav [38]

Answer:

The cost of renting will be the same for 200 miles.

Step-by-step explanation:

Let n the number of miles and C be the cost. We can represent the cost equations for each companies:

A: C = 12 + 0.09n

B: C = 8 + 0.11n

They want to know when the cost will be the same, so we can set the above 2 equations equal to each other and solve for n:

12 + 0.09n = 8 + 0.11n

0.02n = 4

n = 200
