Find the solution to the system of equations: x + 3y = 7
tigry1 [53]

Answer:

(-2,3)

Step-by-step explanation:

Doing it the way you did and working out the problem you substituted 3 into, x+3(3)=7, 3(3) is 9 and then you subtract 9 from both sides.

7-9=-2

x=-2

Then all you have to do is put it into ordered pairs.

jeni works from 8:00-3:15 three days in a row, only taking a half-hour unpaid lunch break each day. if she is paid $15 per hour,
enyata [817]

Jeni gets paid $ 303.75 for 3 days

<em><u>Solution:</u></em>

Given that,

Jeni works from 8:00-3:15 three days in a row

<em><u>Find the number of hours between 8 : 00 to 3 : 15</u></em>

8 : 00 to 3 : 15 = 7 hours 15 minutes

She is taking half-hour unpaid lunch break each day

7 hours 15 minutes - half an hour = 6 hours 45 minutes

So, she works for 6 hours 45 minutes for each three days

6\ hours\ 45\ minutes = 6 + \frac{45}{60} = 6 + 0.75 = 6.75\ hours

She is paid $15 per hour

<em><u>Therefore, total earnings for 3 days is given as:</u></em>

Total\ Earnings = 3 \times 15 \times 6.75\\\\Total\ Earnings = 303.75

Thus she gets paid $ 303.75 for 3 days
