Answer:
10
Step-by-step explanation:
If W is the present age of the woman and D is the present age of the daughter, then:
W = 4D
W + 5 = 3(D + 5)
Substituting the first equation into the second:
4D + 5 = 3(D + 5)
4D + 5 = 3D + 15
D = 10
The daughter is 10 years old.

the fairest school 20% are below 16 years old
1/3 are teachers which is equals to = 21
Let’s start solving:
=> 1/3 of 100% = ( 100 / 3 = 33.33% )
thus 33.33% = 21
=> 21 x 3 = 63, is the total number of people in the school.
Let’s try solving the number of people below 16 years old
Then there are 20% of it:
=> 63 * .20 = 12.6
Thus, there are around 13 people who are 16 years old younger.</span>

Problem:
"Rewrite without absolute value for the given conditions: y=|x−5|+|x+5|, if x>5"
Step-by-step explanation:
Let's figure out when the insides of the absolute values are positive and negative, and then see where the given condition that x>5 fits into that.
if 
is positive or 0,
.
Add 5 on both sides:
.
if is negative or zero, 
.
Add 5 on both sides:
Since then we will choose .

if 
is positive or 0,.
Subtract 5 on both sides:
.
if is negative or zero, .
Subtract 5 on both sides:
Since then we will choose .
