Answer:
W=4h(11-j)/b-h
Step-by-step explanation:
Eliminate variables on the left side first.
b(h+w) = 4h (11-j) - so, divide b by both sides
(h+w)/b=4h(11-j)/b then, eliminate h by subtracting on both sides.
(h+w)-h=4h(11-j)/b - h (h is eliminated on the left side and now you are left with
W=4h(11-j)/b - h

Answer:
The equation to determine the total length in kilometers is ![\frac{h}{2} =(17+2)](https://tex.z-dn.net/?f=%5Cfrac%7Bh%7D%7B2%7D%20%3D%2817%2B2%29)
The total length in kilometers of Josh’s hike is 38 km.
Step-by-step explanation:
Given:
Let the total length in kilometers of Josh’s hike be h.
Now Given that He has now hiked a total of 17 km and is 2 km short of being 1/2 of the way done with his hike.
It means that to reach half of the length of total length Josh needs 2 more km to add in his hiking which is done which is of 17 km.
Framing the above sentence in equation form we get;
![\frac{h}{2}=(17+2)](https://tex.z-dn.net/?f=%5Cfrac%7Bh%7D%7B2%7D%3D%2817%2B2%29)
Hence, The equation to determine the total length in kilometers is ![\frac{h}{2} =(17+2)](https://tex.z-dn.net/?f=%5Cfrac%7Bh%7D%7B2%7D%20%3D%2817%2B2%29)
Now Solving the above equation we get;
First we will multiply 2 on both side using Multiplication property we get;
![2\times \frac{h}{2}= 2\times(17+2)\\\\h =2\times 19 =38 \ km](https://tex.z-dn.net/?f=2%5Ctimes%20%5Cfrac%7Bh%7D%7B2%7D%3D%202%5Ctimes%2817%2B2%29%5C%5C%5C%5Ch%20%3D2%5Ctimes%2019%20%3D38%20%5C%20km)
Hence, The total length in kilometers of Josh’s hike is 38 km.
Answer: concentration = 15.58%
Step-by-step explanation:
Given: mass of sugar = 24 g = 24 ml [ ∵ 1 g = 1 ml]
Volume of solution = Quantity of water + quantity of solute
= 130 +24 ml
= 154 ml
Concentration = ![\dfrac{mass\ of\ solute}{Volume\ of\ solution}\times100](https://tex.z-dn.net/?f=%5Cdfrac%7Bmass%5C%20of%5C%20solute%7D%7BVolume%5C%20of%5C%20solution%7D%5Ctimes100)
![=\dfrac{24}{154}\times 100\\\\\approx15.58\%](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B24%7D%7B154%7D%5Ctimes%20100%5C%5C%5C%5C%5Capprox15.58%5C%25)
Hence, the concentration =15.58%
