Answer:
-1/8 is the answer
Step-by-step explanation:
1.) 1st we have to take 1/2x and make the bottom number 4. so we multiply by 2 and you should get 2/4.
2.) so now the equation should be 3/4x + 5 -2/4x = 3. now you take 3/4x and -2/4x and subtract them and you should get 1/4x.
3.) now the equation should look like 1/4x + 5 = 3. now we need to get all whole numbers to one side. so we will subtract 5 from 5 and that will cancel it out and we need to do that to both sides. so we will subtract 5 from 3 and you will get -2.
4.) now the equation should look like 1/4x = -2. now you put a 1 under the 2 to make it a fraction. it should look like 2/1 and then you are going to flip it because that is how you divide fractions. so now your equation should look like 1/4x = 1/2. now you multiply strait across both bottom and top. and you will get x = -1/8 and that is your answer.
hope this helped!
p.s it would be cool if you gave me brainliest.
They are incorrect because when going from percent to decimal, you divide the percent by 100 and when going from decimal to percent you multiply the decimal by 100. So in the case of 14.5%... divide 14.5% by 100 to get .145. The correct decimal is .145 not 14.5.
