X+y+z=22
(x+y+z+t)/4=8
subsitute
x+y+z=22
(22+t)/4=8
multiplly by 4
22+t=32
subtract 22
t=10
the fourth number is 10
Step-by-step explanation:
4(3x-2) + 6x(2-1)
10x + 11x
21x
Answer:
decrease by 5
Step-by-step explanation:
n= 10
then in sequence,
n= n-5
75.
Explanation: from 3 to 12, you add 9, and then double the 12 to get to 24, and then add 9 again to get to 33, and double it to get 66, so the pattern is to add 9 and then double.
The computation shows that the time when they'll meet each other will be 175 minutes.
<h3>How to illustrate the information?</h3>
From the information, it takes the first student 25 minutes to complete one lap, and it takes the second student 35 minutes to complete one lap.
It should be noted that the time when they'll meet each other will be the lowest common multiple of 25 and 35.
This will be 175 minutes.
