I need help please anyone 10(x-2)+15=8x+7

Answers

10(x−2)+15=8x+7

Simplify

10(x−2)+15=8x+7

(10)(x)+(10)(−2)+15=8x+7(Distribute)

10x+−20+15=8x+7

(10x)+(−20+15)=8x+7(Combine Like Terms)

10x+−5=8x+7

10x−5=8x+7

Subtract 8x from both sides.

10x−5−8x=8x+7−8x

2x−5=7

Add 5 to both sides.

2x−5+5=7+5

2x=12

Divide both sides by 2.

2x/2 = 12/2

x=6

The table shows the results of a survey of 200 movie rental customers:Comedy---> 15%
Mystery---> 10%
Horror---> 46%
Science fiction ---> 29%

How many customers prefer horror movies?

Answers

92 people prefer horror. Explaination: 200 people, and %s are always out of 100. For 200, you can just multiply the number by two to find how many people. Here's the other ones just in case you need these: Horror: 92 people Comedy: 30 people Mystery: 20 people Science fiction: 58 people To make sure you have the right answer, add up all the people to see if you get 200. If you get 200 (I checked, and I did) then you have the right answer.

To work this out, you do 46% of 200, as there are 200 customers asked, and the question asks for the number of customers that prefer horror movies, which is 46%.

You can work that out by doing (200 × 46) ÷ 100 = 92.

92 customers prefer horror movies.
