So for this you just want to divide 4/5 by 9/10 because it is the opposite of the equation.

9/10 / 4/5

To divide fractions, you just multiply and reverse the second fraction.

For example:

9/10 * 5/4

Now you can just normally multiply.

45/40

Or, simplified,

9/8

(Or 1 1/8)

A DVD box set includes 3 thriller movies and 2 comidies. Use t to represent the cost of each thriller and c to represent the cos

suter [353]

Answer:

The expression representing the Total cost of 6 boxes is $6(3t + 2c)$ .

The Simplified expression representing the Total cost of 6 boxes is $18t + 12c$ .

Step-by-step explanation:

Given:

Number of thriller movies = 3

Number of Comedy movies = 2

Let the cost of thriller movie be t

Also Let the cost of comedy movie be c

Total Number of boxes = 6

Now, given a DVD box set includes 3 thriller movies and 2 comedies.

Cost of Each box = $3t + 2c$

We need to find the total cost of 6 boxes

Total Cost of 6 boxes is = $6(3t + 2c)$

Hence the expression representing the Total cost of 6 boxes is $6(3t + 2c)$ .

Simplifying the above expression we get;

Total Cost of 6 boxes is = $6(3t + 2c)= 6\times3t+6\times2c=18t+12c$

Hence the Simplified expression representing the Total cost of 6 boxes is $18t + 12c$ .

Are the lines y = –x – 4 and 5x -5y = 20 perpendicular? Explain.

Zarrin [17]

Answer:

yes

Step-by-step explanation:

If 2 lines are perpendicular then the product of their slopes = - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - x - 4 ← is in slope- intercept form

with slope m = - 1

5x - 5y = 20 ( subtract 5x from both sides )

- 5y = - 5x + 20 ( divide all terms by - 5 )

y = x - 4 ← in slope- intercept form

with slope m = 1

Thus product of their slopes is - 1 × 1 = - 1

Therefore the lines are perpendicular
