You'll also see what happens when you don't follow these rules, and you'll find out why order of operations is so important!
Having difficulty turning a word problem into an algebra equation? With this tutorial, you'll learn how to break down word problems and translate them into mathematical equations.
This tutorial shows you how to take a word problem and translate it into a mathematical equation involving fractions.
Then, you'll see how to solve and check your answer. Check out this tutorial where you'll see exactly what order you need to follow when you simplify expressions.
4 * x = 20 |:4 x = 5 Now that we have calculated the value of the variable, we can tell that Janice rented that bike for 5 hours. If you multiply $4 that Janice paid per hour by the 5 hours she spend with that bike and then add the $10 she had to pay regardless of the time she spent with the bike, you will get a total sum of $30 that is indeed the full sum she paid.
These word problems are called two-step because you have to perform two mathematical operations in order to solve them. Well, she can't sell a decimal number of computers, a third of a computer. If she sells 370 computers, then she's not going to get to break even because that's less than the quantity she needs for break even. She needs to sell 371 computers in a month to make a profit. Or we're going to start getting decimal values. What is the minimum number of computers she needs to sell in a month to make a profit?If you are not confident in your abilities to solve two-step equations with word problems, you can go to one-step equations – word problems and practice some more before continuing with this lesson. First thing we have to do in this assignment is to find the variable and see what its connection is with the other values. 4 * x 10 = 30 Now, in order to make things neater and more clear, let us move all the numbers (except for the number 4 – we have to get rid of it in a different way) to the right side of the equation.But if you feel ready, we will show you how to solve it using this example: Hermione’s Bikes rents bikes for plus per hour. The thing we do not know is the number of hours Janice rented the bike for and we have been asked to find that out. The cost of renting a bike is 10$ to take the bike and 4$ for every hour it spends in our possession. Like this: 4 * x = 30 – 10 To simplify things further, let us perform the subtraction.So I'll let you think about that for a second. So we have x on our right-hand side is going to be equal to 10,000/27. Well, let's think about what we have to figure out. 4 * x = 20 The next thing to do is to get rid of the number 4 in front of the variable.We will do that by dividing the whole equation by 4.Examples, solutions, videos, and worksheets to help Grade 8 students learn how to solve multi-step equation word problems.Learning how to solve word problems is a very important in Algebra.
