The app is actually designed to answer any kind of school question — science, history, etc. For other kinds of questions, Socratic kind of does a bit of Googling, and in my experience can typically find similar word problems on the wide internet, or from its own database of answers.On about half the middle school science problems I tried, the app was able to identify the topic at question and show me additional resources about the concepts involved, but for others it was no more powerful than a simple web search.
I like the Socratic interface and explanations a bit better, but I'm glad to see this is a vibrant market.
When solving this problem students will need to create generalised algebraic equations for each part of the question. Particular attention should be given to order of operation, the correct use of mathematical convention and potential problem areas with the use of language Students should also practice the use of algebraic substitution in a variety of situations including simple numeric substitution into formulas and cases where one algebraic expression is substituted for another.
We will call the smaller integer n, and so the larger integer must be n 2 And we are told the product (what we get after multiplying) is 168, so we know: n(n 2) = 168 We are being asked for the integers Solve: That is a Quadratic Equation, and there are many ways to solve it.
Using the Quadratic Equation Solver we get −14 and 12.
This should result in the following equations: K= ¾ Z, S = ⅔ Z, K = S 15Taking the equation K=S 15 students need to replace the K with K= ¾ Z and the S with S= ⅔ Z thus creating the equation ¾ Z= ⅔ Z 15Students then need to recognise and multiply each of the terms by the common denominator 12, and then solve the resulting equation 9Z= 8Z 15 ∴ Z = 15Students should first review the process of writing algebraic expressions and equations from a worded description or rule.
The resource discusses and explains determining a formula to reinforce students' understanding.
Some algebra problems on the GED Mathematical Reasoning test are straightforward: Solve a given equation for x.
Once you know the basic rules for solving, these are pretty simple.
We know there are seven days in the week, so: d e = 7 And she trains 27 hours in a week, with d 5 hour days and e 3 hour days: 5d 3e = 27 We are being asked for how many days she trains for 5 hours: d Solve: The number of "5 hour" days is 3 Check: She trains for 5 hours on 3 days a week, so she must train for 3 hours a day on the other 4 days of the week.
3 × 5 hours = 15 hours, plus 4 × 3 hours = 12 hours gives a total of 27 hours So Joel’s normal rate of pay is per hour Check Joel’s normal rate of pay is per hour, so his overtime rate is 1¼ × per hour = per hour.
