Question: Ex: The sum of three times a number and 25 is 40. Find the number. 3x + 25= 40 3x + 25 - 25= 40 - 25 3x= 15 x= 5 The number is 5. I don't understand how to find the solution. I thought the solution was what x equals, but I guess not. Here are some problems you can help me figure out : Equation: x- -3 (neggative 3)= 8 WHATS THE SOLUTION? Is it x=5?

yes it is x=5 because think about the way the question is worded. the sum of 3 times a number 3 times x(a number) and 25 . you add 25 because 3 times a number and 25 should equal 40 so it will be 3x + 25 = 40 you subtract 25 from both sides. you get 3x = 15 the divide by 3. you get 3x/3 = 15/3 . you simplify the fractions and get x=5

I tell my boys that the week is meant for school work and that weekends are meant for playing if they maintain good grades and not get in trouble. There are also or should be classes at the school that allow students to go for homework help and or tutoring in the morning, during lunch, and or after school. Education has changed since our earlier days and it has become a more demanding subject for our kids and this leaves very little time for parents or the children to relax. Ask your child's teacher about extra activities at school that will help your child in her daily home-work and web-sites that will aid in her subjects. There is no easy way to save time when it comes to school work and managing time is not an easy task unless your child is just gifted and can do things quickly. Right now all you can do is help her and guide her with examples. Sometimes you will just want to do the work for her in order to get it done quicker but then your child has learned nothing. My wife does that with my boys all the time and they have fallen so far behind, they can't think for themselves and instead of figuring it out they wait and expect the answers instead.

For the equation x- -3 = 8, you solve for x two negatives equals a positive so x+3 = 8 Subtract 3 on both sides so you get x by itself x+3 = 8 -3 -3 x=8-3 x=5 You're right =D

ok this is straightforward. you basically locate the version of the two numbers. So the version between 50 and 40 5 is 5. after which you're making a fraction that's the version of the numbers over the unique quantity. So the fraction would be 5 over 50. once you simplify it, it equals a million over 10. So then you certainly would desire to locate the % of that. that's 10%

this is stupid i'm in geometry honors and still can't answer this.... sorry): i think i need to retake pre algebra haha. i'm pretty sure though in your equation x would equal five, because with a three the two negatives combine to make a positive, so it would be 5 plus 3 equals 8. let me know if thats right?

But, when government continues to abuse its power and takes away the rights and freedoms of its citizens, it is the duty of those citizens to rebel and overthrow that government. Hope that helps :)
