Answer:
d= 3 2/3
Step-by-step explanation:
distribute the 3
combine like terms
add -19 to both sides
divide by 6 on each side
d=3 2/3
Answer:
1/8
Step-by-step explanation:
Look at the screen shots
Distance= the square root of (x2-x1)^2 +(y2-y1)^2 so (-3-(-3))^2 + (23-(-11))^2= 0^2+34^2=
0+1156= 1156 and the square root of that is 34 so your final answer is 34
Answer:
it takes 1st person 4 hour and second person is 8 hours
Step-by-step explanation:
Let t is the time (t >0)
We have:
- 1st person working rate per one task: 1/t-8
- 2nd person working rate per one task: 1/t
- Working rate per one task from 2 person: 1/3
<=> 1/3 = 1/t + 1/t-8
<=>
<=>
<=> t - 7 = 5
<=> t = 12
So it takes 1st person 4 hour and second person is 8 hours
