1. PUT HW ON THE CORNER OF YOUR DESK!
GT Geometry Drill 10/14/14
Identify the hypothesis and conclusion of each conditional.
1. A mapping that is a reflection is a type of transformation.
2. The quotient of two negative numbers is positive.
3. Determine if the conditional “If x is a number then |x| > 0” is true. If false, give a
counterexample.
H: A mapping is a reflection.
C: The mapping is a transformation.
H: Two numbers are negative.
C: The quotient is positive.
F; x = 0.
2. GT Geom Drill
Solve each equation.
1. 3x + 5 = 17
2. r – 3.5 = 8.7
3. 4t – 7 = 8t + 3
4.
x = 4
r = 12.2
n = –38
5. 2(y – 5) – 20 = 0
y = 15
t = –

3. PSAT Practice
1. Which if the following numbers is
divisible by 3 and 5, but not by 2?
A) 955 B) 975 C) 990 D) 995 E) 999
2. There are n students in biology class
and only 6 are seniors. If 7 juniors are
added to the class how many students
in the class will not be seniors?
A) n-3 B) n-2 C) n-1 D) n+1 E) n+2
6. General Look at Multiple Choice
1. Questions are in a E-M-H category.
2. Be careful, they have great wrong answers.
3. Sometimes working from the answer choices
backwards is the easiest way.
4. If you can eliminate 1 or more answers guessing
is good idea.
7. Types of questions
The math categories on the PSAT/SAT are:
Arithmetic, Algebra, Geometry,
Miscellaneous (Data Analysis and
Probability)
The Algebra questions have content from
both Algebra I and Algebra II.
8. Helpful Hints!
The most used and effective
strategy is to substitute a
number for problems that do
not give any values.
9. Substituting
Choose numbers that are easy to
work with for the given problem.
For example, if you know that the
problem says 1/5 of a group of
students….., choose a number divisible
by 5!
