Answer:
280 students
111 non students
Step-by-step explanation:
number of students (S)
number of non students (N)
S+N=391 S=391-N
4S+6N=1786
substitute S
4(391-N)+6N=1786
1564-4N+6N=1786
subtract 1564 from each side
2N=222
N=111
S=391-111=280

Answer: 23 minutes
Step-by-step explanation:
4x + 8 = 100
100 is 8 more than 4 times of minutes than last week.
X = minuted she studied last week.
Find x
4x = 100 - 8
4x = 92
x = 92/4
x = 23 minutes
Answer:
TV = 66
Step-by-step explanation:
Since M is the midpoint, that means the two subsegments are equal so
7x - 2 = 4x + 13
7x - 4x - 2 = 13
7x - 4x = 13 + 2
3x = 15
x = 5
then
TM = 7x - 2 = 7*5 -2 = 35 - 2 = 33
TV = 2 * TM = 2 * 33 = 66
