Setting the coordinate system: positive x points to the east and positive y points to the north. This can be solved by vector addition.

A = <40cos(45), 40sin(45)>
B = <-60cos(60), 60sin(60)>
C = <0, -50>

R = A + B + C = <-1.72, 80.25>

The displacement that needs to return him is by the vector -R.

Therefore, <1.72, -80.25>

Solving rational equations<br><br> solve for x: 3/x-4=7/x
KIM [24]

Solving the rational equation \frac{3}{x-4}=\frac{7}{x} the value of x is 7

Step-by-step explanation:

We need to solve rational equation: \frac{3}{x-4}=\frac{7}{x} and find value of x.

Solving:

\frac{3}{x-4}=\frac{7}{x}

Cross multiplying:

3(x)=7(x-4)\\Simplifying:\\3x=7x-28\\3x-7x=-28\\-4x=-28\\x=-28/-4\\x=7

So, value of x = 7.

Solving the rational equation \frac{3}{x-4}=\frac{7}{x} the value of x is 7

natita [175]

Answer:

This can be found by using the permutations and combinations formuals.

Combinations being the C equation and Permutations being the P equation.

P(n,r)=\frac{6!}{(6-6)!}=720

Explanation:

A permutation is used for the list of data (where the order of the data matters) and the combination is used for a group of data (where the order of data doesn't matter).
