Answer:

Step-by-step explanation:

4x+3y=-5   ...(1)

-3x+4y=12   ....(2)

By 3(1)+4(2) gives

12 x+9y-12x+16y=-15+48

25y=33

y=33/25=1.32

from (1)

4x+3(33/25)=-5

4x=-5-99/25=(-125-99)/25=-224/25

x=-224/100=-2.24

Zigmanuir [339]

Answer:

Kevin is going to be able to have enough money for the concert the fastest

Philip needs at least 4 weeks

Kevin needs at least 3 weeks

Step-by-step explanation:

<u>Philip</u>

  • $8.75/hour * 6 hours/weekend * 1 weekend/week = $52.5/week
  • $45 saved

Let's call x to the number of weeks Philip needs to reach $225.

52.5*x + 45 = 225

52.5*x = 225 - 45

x = 180/52.5

x = 3.43

He needs at least 4 weeks

<u>Kevin</u>

  • 3 hours/day * $7.5/hour *3 days/week = $67.5/week
  • $30 saved

Let's call y to the number of weeks Kevin needs to reach $225.

67.5*y + 30 = 225

67.5*y = 225 - 30

y = 195/67.5

y = 2.9

He needs at least 3 weeks
