Answer:
13
Step-by-step explanation:
The GCF of 36, 48, and 72 is 12 so there will be 36 / 12 = 3 stacks of English books, 48 / 12 = 4 stacks of science books and 72 / 12 = 6 stacks of math books for a total of 3 + 4 + 6 = 13 stacks.
5.The answer for 5 is 582 because you do how many times 4 goes into 2 and that 0.so you bring the 3 down and it goes into 23 5 times.5 times 4 is 20.23-20=3.bring down the 2 and 4 goes into 32 8 times.8 times 4=32.subtract that and get 0.bring down the 8 and 4 goes into 8 2 times.
The answer to 7. is 197 because you do 985 divided by 5.
8. For the Lees you would do 632 divided by 4=$158.For the Santos you would do 328 divided by 2=$164.
The Lees rental cost was lower because when you divide them you get $158 for the Lees and $164 for the Santos.
The first thing we must do for this case is to define variables:
x = rental cost of movies
y = rental cost of video games
We write the system of equations:
6x + 2y = 36
3x + 5y = 39
Resolving we have:
x = 4.25 $
y = 5.25 $
Answer:
The rental cost for each movie and each video game is:
movies = 4.25 $
video games = 5.25 $
Answer:
B
Step-by-step explanation:
p(x) = x² - 2√2x + 1
p(2√2) = (2√2)² - 2√2*2√2 + 1
=2²*(√2)² - 2*2*√2*√2 + 1
= 4 *2 - 4*2 + 1
= 8 - 8 + 1
= 1
The greatest common factor is 7.
