Y is the number of movies
x is the number of hours
It takes 2 hours per movie
Thus:

y = x/2
2y = x
x - 2y = 0

The answer is C

Use the following information to write an equation in terms of x. Then solve the equation and find RS and RT .
Arte-miy333 [17]

Answer:

See below

Step-by-step explanation:

Assuming a number line:

rs + st  = rt

3x-16   +    4x-8    = 60  

7x  -24   = 60

7x = 84

x = 12

Help guysss im in 6th really need help

5 times as many. Since dog B has 2 and dog A has 10, A = 2 * X, since you’re solving for the multiplication comparison. 10/2 = 5, so you’ve got 5 times as many.

Answer:

. We assume, that the number 260 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 260 is 100%, so we can write it down as 260=100%.

4. We know, that x is 6.75% of the output value, so we can write it down as x=6.75%.

5. Now we have two simple equations:

1) 260=100%

2) x=6.75%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

260/x=100%/6.75%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 6.75% of 260

260/x=100/6.75

(260/x)*x=(100/6.75)*x       - we multiply both sides of the equation by x

260=14.814814814815*x       - we divide both sides of the equation by (14.814814814815) to get x

260/14.814814814815=x

17.55=x

x=17.55

now we have:

6.75% of 260=17.55
