I'm not sure if that's what you mean, but the difference between 6010 and 5060 is 950, so to find a number in a halfway between them I divided 950 by 2 (which is 475) and added it to 5060 (or substracted from 6010 - it's the same). Next I added the same number (475) to 6010. So finally it would like like this:
6,485 ; 6,010 ; 5,535 ; 5,060
hw: 3/2hrs = 3×30 = 90mins
chores: 1/2hr = 1×30 = 30mins
sleep: 17/2hrs = 17×30 = 510mins
90+30+510=630mins=10.5hrs/day
The answer is the last one (-20)

Step-by-step explanation:
Explanation:
Substitute
tan
(
y
x
)
for
θ
tan
(
y
x
)
=
π
3
Obtain
y
x
on the left by using the inverse tangent on both sides:
tan

(
tan
(

)
)
=

)
y
x
=
tan
−
1
(
π

)
Multiply both sides by x:
y
=
