9x is your answer hope this helped a lot
Answer:
9
Step-by-step explanation:
If I’m understanding you correctly, the answer would be nine. Any number with a 9 in the one’s place (unit digit) would still have a nine in that place after being cubed.
29³=24,389
69³=328,509
Number of Adults = a
Number of children = 2a
Number of people in a group = 45
so
a + 2a = 45
3a = 45
a = 15
Number of Adults = 15
Number of children = 30
Answer:
a. there are sometimes infinitely many solutions to the system
b. will always have one solution
c. There is never any solution for the system
Step-by-step explanation:
22a If two lines have the same slope, they can either be parallel lines which never intersect and have no solution or the same line which have infinite solutions. So there are sometimes infinitely many solutions to the system depending on if they are the same line or are parallel lines
b If the lines have different slopes, they will eventually intersect each other at a point, so they will always have one solution
c. If the lines have the same slope and a different y intercept, they are parallel lines and will never intersect. There are no solutions when they never intersect. There is never any solution for the system
Okay all the triangles equal to 180 , so you have to add the numbers that it gives you , then subtract by 180
. for example: 33+75?= 180
33+75= 108
180-108 =72
therefore your answer is 72 (for my example)
