Answer:
x=2
Step-by-step explanation:
<u>Step 1: Simplify both sides of the equation.</u>
3(x−4)=2(−2x+1)
(3 )(x)+(3 )(−4)=(2) (−2x)+(2) (1)(Distribute evenly)
3x+(−12)=−4x+2
3x−12=−4x+2
<u>Step 2: Add 4x to both sides.</u>
3x−12+4x=−4x+2+4x
7x−12=2
<u>Step 3: Add 12 to both sides.</u>
7x−12+12=2+12
7x=14
<u>Step 4: Divide both sides by 7.</u>
7x
/7
=14
/7
x=2
Answer:
7
Step-by-step explanation:
First, you need to plug in the values for x. Here, we know that x = 5. So, when we plug it in we get 2^5 - 5^2. When we simplify, we then get 32 - 25. Thus, 32 - 25 = 7.
This is pretty simple once you think about it, you are probably just making it harder than it needs to be :) So, all you really have to do is plug in the numbers and see which statement is true. So, for the first one, you should work it out with me in the comments. Sorry lol I don't really like giving straight answers. lol
1,655,000 maybe I not entirely sure sorry
Answer: it is invalid
Step-by-step explanation: it is invalid because the data table has 30 out of 100 people stating that they prefer to view movies in theater. This does not have the same ratio as 300 out of 400, and would only work had he said 300 out of 1000. Thus, he is incorrect in his inference.
