take father's age as x
if it is doubled i.e 2x .we get the answer as 20 less than 100 which means 100-20=80
accordingly the equation will be 2x=80
x=40
given that ,
son is 1/4 th of his father
hence ,
son = 1/4×(x)
I.e, 1/4×40 =10
Hope it helps
5x = 10/7
x = (10/7) / 5
x = 10/7 * 1/5
x = 10/35 which reduces to 2/7 <==
Answer:
2730 possible ways
Step-by-step explanation:
Given


Required
Number of possible selections
Since there is no restriction, the number of selection is calculated as:
The day nursing supervisor position can be occupied by any of the 15 applicants
The night nursing supervisor position can be occupied by any of the remaining 14
The nursing coordinator position can be occupied by any of the 13
So, the number of ways is then calculated as:


<em>Hence, there are 2730 possible ways</em>

x≤-7

First , use the distributive property :
3(x-4)≥5x+2
3x-12≥5x+2
Subtract 5x on both sides :
3x-5x-12≥2
Now , add 12 on both sides :
3x-5x≥2+12
3x-5x≥14
Subtract the x's :
-2x≥14
Divide by -2 on both sides and watch what happens :
x≤-7 (notice that the inequality sign changed from "greater than or equal to" to "less than or equal to")
If we divide both sides of an inequality by a negative number , we change the inequality sign .
