Answer:
68
Step-by-step explanation:
Answer:
D) (5,0)
Step-by-step explanation:
-5x + 4 ≤ y
-25 + 5 ≤ 0
-20 ≤ 0
y ≤ 2x + 2
0 ≤ 2(5) + 2
0 ≤ 27
45+-17
This is the same as subtracting 17 from 45
45-17=28
Answer:
Number of children, x= 400
Number of adults, y = 100
Step-by-step explanation:
Let the number of children be x
Let the number of adults be y
Given : Total number of people, x + y = 500 --------(1)
Total amount collected, 5x + 10y = 3000 ---------(2)
(1) => y = 500 - x
Substitute y in (2) : 5x + 10(500 - x) = 3000
5x + 5000 - 10x = 3000
-5x = 3000 - 5000
-5x = -2000
x = 400
Substitute x in (1) : 400 + y = 500
y = 500 - 400
y = 100
The awnser is one I hope I helped you with this question
