40-15=25 students not on student council
25/40 = .625 decimal
multiply by 100 to get percent
62.5% of students are not on student council
Estimating:
15 rounds to 20 and 40 rounds to 50
40% are in student council and that leaves roughly 60% not in student council.
Answer:
400
Step-by-step explanation:
8% of 5000 is 400. Math:
5000 x 0.08 = 400
16.454 is greater than 16.45.
Answer:
The correct answer is the first solution set.
Step-by-step explanation:
If we substitute -20 into the equation we get
-20+17≤-3
-3≤-3
So,the inequality is right.
We can check the second one
14+17≤-3
31≤3 The inequality is false.
We can check the last one
-20+17≤-3
-3≤3 It works however there is a difference between the first one and the last one and that is the sign.For the first one there x≤-20 meaning the greatest number x can be is -20.For the last one x≥-20 which means -20 is the least value x can be.
If we substitude -21 into the equation we get
-21+17≤-3
-4≤-3
The inequality is false because -4 is not smaller than -3.
So,the right answer is the first solution set.
