Answer:

Givens:

  • Peter 3 hours every day.
  • Cindy works 2 hours every day.
  • Each of them get $4.50 per hour.

So, from the problem we can deduct that Peter earns $4.50(3 hours/day) = $13.50 per day. And Cindy earns $4.50(2 hours/day) = $9.00 per day. Therefore, Peter daily earning are higher than Cindy's, this can be expressed with the following inequality:

Peter's daily earnings > Cindy's daily earnings

$13.50 > $9.00

On the other hand, if Cindy earns at least $14 per day, that means she earns $14/2 hours per day = $7 per hour, because she only works 2 hours each day. But, the problem says "at least", so the correct expression would be

Cindy's \ earning \geq 7 \frac{\$}{hour}

Tell whether the ordered pair is a solution of the system of equations.
katovenus [111]

Answer:

2x + y = 5

y = 4x – 1

Substitute (2, 1) into system, then:

2x + y = 5  => 2 x 2 + 1 = 5 => 5 = 5 (satisfied)

y = 4x– 1   => 4 x 2 - 1 = 1  => -7 = 1 (not satisfied)

=> Option 3 is correct.

Hope this helps!
