school for 3 day . the number
of tickets sold during the first ,
second and third days were
1234, 875 and 1786 respectively . each ticket
costs 50 . what will be the
total amount of money collected through selling the
tickets for all 3 day?
​

Answer 1

Answer:

Students use algebra to solve equations (of the form px + q = r and p(x + q) = r where p, q, and r are specific rational numbers); using techniques of making zero (adding the additive inverse) and making one (multiplying by the multiplicative inverse) to solve for the variable.

• Students identify and compare the sequence of operations used to find the solution to an equation algebraically, with the sequence of operations used to solve the equation with tape diagrams. They recognize the steps as being the same.

• Students solve equations for the value of the variable using inverse operations; by making zero (adding the additive inverse) and making one (multiplying by the multiplicative inverse).

Lesson 23 Summary

• Equations are useful to model and solve real-world problems. The steps taken to solve an algebraic equation are the same steps used in an arithmetic solution.
