Answer:
Option D is correct
Step-by-step explanation:
-4(3x/2 - 1/2) = -15
<=>
-4*3x/2 + (-4)*(-1/2) = -15
<=>
-6x + 2 = -15
<span>Hello, Yoloalanis. In order to solve this question that you have just posted, you only have to do a few simple steps. So, We can do this!</span>
<span />Let's start with your fraction. You will first have to change 9/12 into a decimal. In order to do this, you will have to divide the numerator by the denominator. A numerator is also known as the top part of the fraction. A denominator is the bottom part of the fraction. So, when you divide nine by twelve, you get 0.75 as a decimal. Now, you just have to multiply the decimal by 100 or to make it simpler, just move the decimal two places to the right. To sum it all up, you will get 75%.
Hope it helps :)
Answer: Jimmy has 20 more apples than Karl.
Step-by-step explanation:
40 - 20 = 20
Answer:
28%
Step-by-step explanation:
On Thursday night Anna had 20% of the votes, Ivan had 35% of the votes and Elena had 45% of the votes. You can take the number of total votes on Thursday equal to 100, then Anna had 20 votes, Ivan had 35 votes and Elena had 45 votes.
Let x be the number of votes added on Friday. All of them favored Elena, then Elena in total had 45+x votes and the number of all votes became 100+x. In the end Anna had 16%, then
100+x - 100%,
20 - 16%.
Write a proportion:
Find the percent of the voters that chose Ivan:
125 - 100%,
35 - y%.
Write a proportion:
3x would have to be 15/2.
Since we have that 5x+3x=5x+15/2, the only pieces that are different are the 3x and the 15/2. This gives us the equation
3x=15/2
If we were to go on and solve this equation, we would multiply by 2, giving us
6x=15
Then we would divide by 6:
6x/6=15/6
and x=2.5.
