Answer:
1/20=10 years old
In a school 50% of the students are younger than 10, 1/20 are 10 years old and 1/10 are older than 10 but younger than 12, the remaining 70 students are 12 years or older. How many students are 10 years old?
50%= younger than 10
1/20=10 years old
1/10=older than 10 younger than 12
70=12 years or older
50%- 10/20
1/20-1/20
1/10-2/20
10/20+1/20+2/20=13/20
70 students =7/20
1/20 = 10 years old.
7/20 divided by 7 = 1/20
70 divided by 7=10
10 students are 10 years old
Answer: D and E
Step-by-step explanation:
To find this answer we want to get x by itself in the equation.
6x + 4 < 22
6x < 18
x < 3
So according to this the value of x has to be less than 3.
You can check your answer by substituting the values in for x.
6(0) + 4 < 22
4 < 22 is True
6(2) + 4 < 22
16 < 22 is True
6(3) + 4 < 22
22 < 22 False!
