Answer:
64/7 i think
Step-by-step explanation:
whole trip ---- x km
day1 , hiked 1/8 of train, leaving (7/8)x
day 2 , hiked 4/7 of (7/8)x leaving
(3/7)(7/8)x or (3/8)x to be hiked
day3 :
(1/3)(3/8)x + 8 = x
x/8 + 8 = x
times 8
x + 64 = 8x
7x = 64
the trail is 64/7 km
check:
day 1 they hiked (1/8)(64/7)
leaving (7/8)(64/7) = 8 km
day2, hiked 4/7 of remaining, leaving
(3/7)(8) or 24/7 km
day 3
(1/3)(24/7) + 8
= 64/7
yeahhh!
Answer:
27.4
Step-by-step explanation:
First multiply the numerator and denominator by 10
Then write the problem in long division format
Then divide 52 by 19 and get 2
Then multiply the quotient digit (2) by the divisor 19
Then subtract 38 from 52
Then bring down the next number of the dividend
Then divide 140 by 19 to get 7
Then multiply the quotient digit (7) by the divisor 19
Then subtract 133 from 140
Then add a decimal point to the solution
Then bring down the next number of the dividend
Then divide 76 by 19 to get 4
Then multiply the quotient digit (4) by the divisor 19
Then subtract 76 from 76
The solution for long division for 52.06./1.9 is 27.4

Answer:
(2,3)
Step-by-step explanation:
-x-(x+1)=-5
-2x-1=-5
-2x=-4
x=2
y=3
Answer:
3
Step-by-step explanation:
There is no x in the equation, so I will assume solving for m
Distribute:
3m + 21 = 6m + 12
Subtract 3m and 12
3m = 9
Divide by 3
m = 3
Answer:
Distance Jamie must sprint to reach Shelly is; L = 107 m
Step-by-step explanation:
We are given;
Central angle;θ = 123°
Radius;r = 50m
Now, for us to find out how many meters Jamie must sprint to reach Shelly, we'll use the formula for arc length of a circle;
Arc length; L = 2πr(θ/360)
So, plugging in the relevant values, we have;
L = 2π(50)(123/360)
L = 107.34 ≈ 107 m
L = 107 m
