Answer:

x = 1

Step-by-step explanation:

Given

- 2x + 4 = 8x - 6 ( subtract 8x from both sides )

- 10x + 4 = - 6 ( subtract 4 from both sides )

- 10x = - 10 ( divide both sides by - 10 )

x = 1

The play director spent 190190 hours preparing for a play. That time included attending 3535 rehearsals that took varying amount
gavmur [86]

Answer:

The equation 35x+93\frac{3}{4}=190 gives average time spent on 35 rehearsals.

Step-by-step explanation:

We have been given an equation 35x+93\frac{3}{4}=190 and we are supposed to find that the given equation helps to find answer of what question.

We can see that 93\frac{3}{4} is time spent on other responsibilities related to play and 35x represents time spent on 35 rehearsals. The sum of these times equals to total time spent on preparing the play.

Now let us solve our equation step by step.

35x+\frac{375}{4}=190  

After subtracting \frac{375}{4} hours from 190 hours we will get time spent on 35 rehearsals.

35x+\frac{375}{4}-\frac{375}{4}=190-\frac{375}{4}  

35x=\frac{760}{4}-\frac{375}{4}  

35x=\frac{760-375}{4}  

35x=\frac{385}{4}  

35x=96.25  

Time spent on 35 rehearsals is 96.25 hours and we are told that each rehearsal took different amount of time. Dividing 96.25 by 35 we will get average time spent on each rehearsal.

\frac{35x}{35}=\frac{96.25}{35}

x=2.75  

Therefore, equation 35x+93\frac{3}{4}=190 finds average time spent on 35 rehearsals.

Is 1/2 equivalent to 5/8
kompoz [17]
<span>No. 

To check this yourself, you need the denominators to be the same to be able to easily compare the two. 

For example, does 5/8 = 40/64? 

1. Determine what you would need to do to the denominator in 5/8 to make it 64. (Multiply it by 8) 
2. Find what fraction is equal to 1 with a denominator of 8. (8/8) 
3. Multiply the fraction 5/8 by the one you just found (8/8), numerator times numerator, denominator times denominator. 
4. Compare the answer with the second fraction. 

It is important that when you multiply the denominator by any number you multiply the numerator by the same number. This is to preserve the fraction's value. This works because any number divided by itself is equal to 1, AND when you multiply any number by 1 (whether 1 is in the form of 1 or 4/4 or 8/8 or 234/234), the answer is always equal to the original number. 

Another way to check would be to simply enter 1/2 into a calculator, write down the answer. Next enter 5/8 into a calculator. If the answers are the same, they are equal.</span><span>
