Tim has $90 and spends $12.00 each week. Which equation calculates his spending over 3 weeks?
A = 90 - 3 × 12
A = 90 - 3 + 12
A = 90 / (3 × 12)
A = (3 × 90) / 12

Tiles are arranged on each side of the line to represent an equation. What is the equation?
<i>2x</i> = -1, <i>x = -1</i>
<i>2x</i> = 1, <i>x = 1</i>
<i>x - 2</i> = -1, <i>x = 1</i>
<i>x + 2</i> = 1, <i>x = -1</i>
What is the equation for the starting temperature of a temperature drop of 9°C to -3°C?
