Question

Natasha charges $12 per hour for babysitting in her neighborhood. What equation relates her pay for a job to the number of hours she works? (use "p" to represent pay and "h" to represent the hours that she babysits)
1. p=12h

2. h=12p

3. p=12 + h

4. h= 12- p

Answer 1

Answer:

4

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).
