Solve the system and give your answer as a coordinate point in the form (k, c) k+c=100 51k+11c=2500
Aleks [24]

Answer:

k = 35, c = 65

Step-by-step explanation:

Solve the following system:

{c + k = 100 | (equation 1)

{11 c + 51 k = 2500 | (equation 2)

Swap equation 1 with equation 2:

{11 c + 51 k = 2500 | (equation 1)

{c + k = 100 | (equation 2)

Subtract 1/11 × (equation 1) from equation 2:

{11 c + 51 k = 2500 | (equation 1)

{0 c - (40 k)/11 = -1400/11 | (equation 2)

Multiply equation 2 by -11/40:

{11 c + 51 k = 2500 | (equation 1)

{0 c+k = 35 | (equation 2)

Subtract 51 × (equation 2) from equation 1:

{11 c+0 k = 715 | (equation 1)

{0 c+k = 35 | (equation 2)

Divide equation 1 by 11:

{c+0 k = 65 | (equation 1)

{0 c+k = 35 | (equation 2)

Collect results:

Answer: {c = 65 , k = 35

You earn $46,530 as your annual salary . what is your biweekly salary?
Vlada [557]

Answer:

1,789.62

Step-by-step explanation:

It can be solved two ways:

1. divide the annual salary (46,530) by the number of weeks in a year (52) then multiply by 2 for bi-weekly.

46530/52 = 894.81 x 2 = 1,789.62

2. divide the annual salary (46,530) by the number of bi-weekly pay periods (26)

46520/26 = 1,789.62
