(1,3)

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

the answer is 21%.

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
