Answer:
18 1/8
Step-by-step explanation:
4 7/8 x 4 = 23 1/2
23 1/2 - 5 3/8 = 18 1/8
Answer:
18 students
Step-by-step explanation:
60% of 30
(60*30)/100
1800/100 = 18 students
3x + y = -2 so y = -3x - 2
and
x - 2y = 4
substitute y = -3x - 2 into x - 2y = 4
x - 2y = 4
x - 2(-3x - 2) = 4
x + 6x + 4 = 4
7x = 0
x = 0
y = -3(0) - 2
y = -2
solution (0 , -2)
Answer
B. There is exactly one solution at (0, -2)
