The cost of each campstools, tent and sleeping bag is $20, $100 and $26
let
tent = 1
sleeping bags = 2
campstools = 3
Total cost = $212
tent = t
sleeping bags = s
campstools = c
If
t = 5c
s = c + 6
Total = t + 2s + 3c
212 = 5c + 2(c + 6) + 3c
212 = 5c + 2c + 12 + 3c
212 = 10c + 12
212 - 12 = 10c
200 = 10c
c = 200/10
c = 20
t = 5c
= 5 × 20
= 100
s = c + 6
= 20 + 6
= 26
Therefore, the cost of each campstools, tent and sleeping bag is $20, $100 and $26

Answer:
y-3= -3.(x+10)
Step-by-step explanation:
Answer:
-1/3 (7 + 2 sqrt(10))
Step-by-step explanation:
(sqrt(2)+sqrt(5))
-------------------
sqrt(2)- sqrt(5)
We need to multiply the top and bottom by the complex conjugate of the bottom. The complex conjugate of the bottom is sqrt(2) + sqrt(5)
(sqrt(2)+sqrt(5)) * (sqrt(2)+sqrt(5)
----------------------------------
(sqrt(2)- sqrt(5)) * (sqrt(2)+sqrt(5))
FOILing the top and bottom
(2+sqrt(10) + sqrt(10)+5)
----------------------------------
(2- sqrt(10) +sqrt(10)-5)
(7+2sqrt(10))
----------------------------------
-3
-1/3 (7 + 2 sqrt(10))
