No, I didn’t go back to high school ☺; it was one of those student-parent-teacher conference thingys with my 8th grader today. And his Math teacher thought it would be a novel way for the parents to see what the kids have learnt in Math this past school year.
My son does Algebra. (They split the kids up according to ability: Pre-Algebra, Algebra & Geometry with the majority of kids doing Pre-Alg while Algebra & Geometry are considered faster-track courses). So I had to do an Algebra quiz.
Here are some of the problems I had to solve, starting with the easiest ones first:
David has 83 coins in nickels (5 cents) & dimes (10 cents). He has a total of $6.95. How many of each coin does he have?

Simplify:

Solve the equation if possible:

Factor by grouping
rs – 6r – 5s + 30
Here are some I couldn’t do:
Write an equation in slope-intercept form for the line described below:
Containing (4,8) and (-2, -1)

Solve:

Graph the system of inequalities and state the solution:

(it’s been eons since I’ve drawn graphs from equations….!!!)
Considering the fact that it’s been more than 20 years since I’ve worked on mathematical formulae and that my brain has been used for memorizing medical facts more than anything else in the last half of my life, I was not too disappointed with my score ☺ .
Besides, two other parents there who took the PRE-Algebra quiz scored a ZERO and a 5 out of 10, respectively....hehehe...
