Step-by-step explanation:
Kenny can buy 15 t shirts and 3 sweatshirts.
Step-by-step explanation:
Given,
Number of members = 18
Cost of each t shirt = $9
Cost of each sweatshirt = $15
Money = $180
Let,
x be the number of t shirts
y be the number of sweatshirts
According to given statement;
x+y=18 Eqn 1
9x+15y=180 Eqn 2
Multiplying Eqn 1 by 9

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 6

Putting y=3 in Eqn 1

Kenny can buy 15 t shirts and 3 sweatshirts.

Answer:
The problem with this question is that it is missing an important number, which is the length of the tube. Assuming that the tube is 10 meters long (=1,000 centimeters long)
time (in distance traveled distance traveled distance
seconds) by particle A in cms by particle B in cms between both
particles in cms
1 97 49 854
2 93 47 714
3 89 45 580
4 85 43 452
5 81 41 330
6 77 39 214
7 73 37 104
8 69 35 0
After 8 seconds both particles should meet. Particle A traveled 664 centimeters and particle B traveled 336 centimeters.
