Answer:

(2, 4 )

Step-by-step explanation:

Given the 2 equations

y = 2x → (1)

x = - y + 6 → (2)

Substitute x = - y + 6 into (1)

y = 2(- y + 6) ← distribute

y = - 2y + 12 ( add 2y to both sides )

3y = 12 ( divide both sides by 3 )

y = 4

Substitute y = 4 into (2) for corresponding value of x

x = - 4 + 6 = 2

solution is (2, 4 )

Assume that your present job pays a monthly gross salary of $1,560. You are offered a new position that pays $8.60 per hour with

motikmotik

Answer:

There are 4 weeks in a month and 40 working hours in a week

Since the $8.60 per hour, the gross monthly salary for your new position = 8.60*40*4 = $1,376

Your gross monthly salary at present job = $1,560

So the additional amount that you need to earn at your new position = 1,560-1,376 = $184

The hourly wage for addtional hours more than 40 hours at the new position = 1 1/2 * 8.60 = 1.5*8.60 = $12.90

So, number of hours that you need to work extra = 184/12.90 = 14.26 hours per month

So, number of hours that you need to work extra per week = 14.26/4 = 3.566 hours or 3.57 hours (Rounded to 2 decimals)
