To give you a better overall experience, we want to provide relevant ads that are more useful to you.
There are a couple of things you need to do when solving problems.
Ask yourself exactly what type of information is being asked for: Is it one of addition, subtraction, multiplication, or division?
We also use this information to show you ads for similar films you may like in the future.
Like Oath, our partners may also show you ads that they think match your interests.
Once you’ve identified your clue words, highlight or underline them.
This will let you know what kind of problem you’re dealing with.Children can practice the worksheets of all the grades and on all the topics to increase their knowledge. = $ (x 145 145) = $ (x 290) So in this way end of every week her salary will increase by $ 145. The value of x x(x) = 2 2(2 × 2) = 2 2(4) = 2 8 = 10 Answer: (a) 3. On the sale of the pipes, he: (a) broke even, (b) lost 4 cents, (c) gained 4 cents, (d) lost 10 cents, (e) gained 10 cents 20 % profit on $ 1.20 = $ 20/100 × 1.20 = $ 0.20 × 1.20 = $ 0.24 Similarly, 20 % loss on $ 1.20 = $ 20/100 × 1.20 = $ 0.20 × 1.20 = $ 0.24 Therefore, in one pipe his profit is $ 0.24 and in the other pipe his loss is $ 0.24. His new time compared with the old time was: (a) three times as much, (b) twice as much, (c) the same, (d) half as much, (e) a third as much Let speed of the 1st trip x miles / hr. The ordered pair (100, 212) is also an ordered pair of this function because 100°C is equivalent to 212° F, the boiling point of water. Then use this formula to determine the number of sports fields in 720 feet. A recipe calls for 2 1/2 cups and I want to make 1 1/2 recipes. Since both profit and loss amount is same so, it’s broke even. The distance light travels in one year is approximately 5,870,000,000,000 miles. In order to have a yearly income of $ 500, he must invest the remainder at: (a) 6 % , (b) 6.1 %, (c) 6.2 %, (d) 6.3 %, (e) 6.4 % Income from $ 4000 at 5 % in one year = $ 4000 of 5 %. In Math-Only-Math you'll find abundant selection of all types of math questions for all the grades with the complete step-by-step solutions. So after completing the 1st week she will get $ (x 145). Remaining income amount in order to have a yearly income of $ 500 = $ 500 - $ 340. We know that, Interest = Principal × Rate × Time Interest = $ 160, Principal = $ 2500, Rate = r [we need to find the value of r], Time = 1 year. 160 = 2500r 160/2500 = 2500r/2500 [divide both sides by 2500] 0.064 = r r = 0.064 Change it to a percent by moving the decimal to the right two places r = 6.4 % Therefore, he invested the remaining amount $ 2500 at 6.4 % in order to get $ 500 income every year. Jones covered a distance of 50 miles on his first trip. So, times taken to covered a distance of 50 miles on his first trip = 50/x hr. Fahrenheit temperature F is a linear function of Celsius temperature C. Parents and teachers can follow math-only-math to help their students to improve and polish their knowledge. Similarly after completing the 2nd week she will get $ (x 145) $ 145. Based on the cost, his profit one was 20% and his loss on the other was 20%. Income from $ 3500 at 4 % in one year = $ 3500 of 4 %. On a later trip he traveled 300 miles while going three times as fast. And times taken to covered a distance of 300 miles on his later trip = 300/3x hr. So we can clearly see that his new time compared with the old time was: twice as much. The ordered pair (0, 32) is an ordered pair of this function because 0°C is equivalent to 32°F, the freezing point of water. Write a formula that gives the length of x sports fields in feet. If you begin to solve problems by looking for clue words, you will find that these words often indicate an operation. The first thing to do when you encounter a math problem is to look for clue words.This is one of the most important skills you can develop.Then do the following: Read the problem carefully, and decide on a method to solve the problem.Once you've finished working the problem, check your work and ensure that your answer makes sense and that you've used the same terms and or units in your answer.Then determine all the information that is being given to you in the question.Mathematician George Pólya’s book, “How to Solve It: A New Aspect of Mathematical Method,” written in 1957, is a great guide to have on hand.
