Working together three workers would take 1 hour 36 minutes to finish the job
<em><u>Solution:</u></em>
Given that first worker can finish the job in 8 hours
So in one hour, first worker can do 
th of the work
The second worker can finish the job in 4 hours
So in one hour, second worker can do 
th of the work
The third worker can also finish the job in 4 hours
So in one hour, third worker can do th of the work

Step-by-step explanation:
(7+9)/(-5-5)= 16/-10= -8/5
y + 9 = -8/5(x - 5)
y + 9 = -8/5x + 8
y = -8/5x - 1
Answer:
X=-5
Step-by-step explanation:
Start by isolating the variable to one side. So from here we would add 68 to both sides. we will be left with -8 1/4x = -6.25x+10. Then add 6,25 to both sides to cancel on and get -2x=10. Divide both sides by -2 to get x=-5
H=height of ostrich
k=height of kiwi
h is 20 more than 4 times k
k=20+4k
k=108
108=20+4k
minus 20 from both sides
88=4k
divide both sides by 4
22=k
answer is A
