Going upstream: 432 km / 6 hours = 72 km/h
Going downstream: 384 km / 4 hours = 96 km/h
Going upstream against the current means that the effective speed is:
r_boat - r_current = 72
Meanwhile, going downstream with the current means;
r_boat + r_current = 96
Adding both equations (to cancel out r_current) gives:
2r_boat = 72 + 96
r_boat = 84 km/h
Substituting back into one of the original equations: r_current = 12 km/h.
Answer:
Employers such as a company or organization that provide service or product to the employee and any person hire service from the employer, for which the employee has to pay. An employee is an individual or organization that work full time or part-time according to requirements and receive compensation for the services.
Step-by-step explanation:
Y=(1/5)^x would be the only equation demonstrating decay of these
To solve the equation:
![\frac{u - 3}{4} = 4 \\ \frac{u - 3}{4} \times 4 = 4 \times 4\\ u - 3 = 4 \times 4 \\ u - 3 + 3 = 16 + 3 \\ u = 16 + 3 \\ u = 19](https://tex.z-dn.net/?f=%5Cfrac%7Bu%20-%203%7D%7B4%7D%20%20%3D%204%20%5C%5C%20%5Cfrac%7Bu%20-%203%7D%7B4%7D%20%20%5Ctimes%204%20%3D%204%20%20%5Ctimes%204%5C%5C%20u%20-%203%20%3D%204%20%5Ctimes%204%20%5C%5C%20u%20-%203%20%2B%203%20%3D%2016%20%2B%203%20%5C%5C%20u%20%3D%2016%20%2B%203%20%5C%5C%20u%20%3D%2019)
Therefore, the answer is u=19.
Hope it helps!
Answer:
To solve an equation you can use PEMDAS, standing for parenthesis, exponents, multiplication, division and addition. If it's an equation like, x/3+7+13, you could use the distributive property. By separating variables.
