The highest common factor of the two terms is 3, so that goes outside the bracket as 3(____). To get 3x^2, you multiply 3 by x^2, which is your first term in the bracket, and to get -21, you multiply 3 by -7, so your final answer is 3(x^2 - 7). I hope this helps!
49 * 3 = 147
147 - 55 - 28 = 64
They scored 64 points the third game
To check the answer do 55 + 64 + 28, which equals 147, and divide that by 3, which equals 49.
Answer:
Step-by-step explanation:
<u>Add up as fractions:</u>
- 1/2 + 2/5 = Common denominator is 2*5 = 10
- 5/10 + 4/10 =
- 9/10
Option D
#3. the probability of spinning "rock" is 25% or 1/4 so we can use this probability to predict the number of times we would expect to get "rock" in 80 spins as follows:
25% of 80 = .25(80) = 20 So how likely is it we spin 20 'rock' out of 80 spins? At 25%, not very likely..
#4.
A. True
B. True
C. False, the theoretical probability of make make using the spinner is

or about 56%
