Unit Warm-Up
In this unit, we will use previously learned algebra and geometry skills. Let’s review just a few important ones before beginning.
Think & Click: Unit Warm-Up
Complete the Think & Click activity by looking at each problem below, thinking about it, and then clicking on the question to reveal the solution.
If segment AB has length 5x – 7 and segment XY has length 3x + 11, what value of x would make the segments congruent?
5x – 7 = 3x + 11
5x = 3x + 18
2x = 18
x = 9
What is the length of segment AB and XY?
AB = 5(9) – 7 = 45 – 7 = 38
XY = 3(9) + 11 = 27 + 11 = 38
Name three fractions that are equivalent to 
.
Many answers are possible: 
are three possible answers.
If two angles in a triangle are 46° and 72°, what is the measure of the third angle?
180 – 46 – 72 = 62°
