Q1Linear equations

Solve for x: 4x − 9 = 23

A6 B7 C8 D9

Answer: C

Add 9 to both sides → 4x = 32, then divide by 4 → x = 8.

Q2Distribute & solve

If 2(x + 3) = 16, what is x?

A5 B6 C8 D10

Answer: A

Divide both sides by 2 → x + 3 = 8 → x = 5. (Or distribute: 2x + 6 = 16 → 2x = 10 → x = 5.)

Q3Slope

A line passes through (1, 2) and (3, 8). What is its slope?

A2 B3 C4 D6

Answer: B

Slope = Δy ÷ Δx = (8 − 2) / (3 − 1) = 6 / 2 = 3.

Q4Systems

If y = x + 2 and 2x + y = 11, what is x?

A2 B3 C4 D5

Answer: B

Substitute y = x + 2 into 2x + y = 11 → 2x + (x + 2) = 11 → 3x + 2 = 11 → 3x = 9 → x = 3.

Q5Translate to algebra

A phone plan costs $20 per month plus $0.10 per text. Which expression gives the monthly cost for t texts?

A20t + 0.10 B0.10t + 20 C20 + 10t D0.10 + 20t

Answer: B

The $20 is fixed; the per-text cost is $0.10 × t. Total = 0.10t + 20. (A trap: 20t would charge $20 per text.)

How to wire the email button

Already wired. This mini-lesson posts to your Formspree endpoint formspree.io/f/mpqgdkww — when a student submits, you get an email with their name, every answer, and the score. Nothing to set up.

Alternative — Zapier. If you ever want to route results elsewhere, make a Zap with a Catch Hook trigger and set the form's action to that webhook URL instead.

Note: the button sends only when this file is opened in a normal browser (or hosted) — not inside a preview pane. The same wiring drops into all 10 mid-week mini-lessons; only the subject line and questions change.
