4 0

Answer:

18 nickels, 9 dimes, 6 quarters.

Step-by-step explanation:

Basically, I just made a money table and used it to get my equation, which is: 60x-30=330, to get how many quarters there are. Then, plug that in to the problem and you have your answer.

Answer:

  • Cost of fish = Php. 60, amount of fish = x kg
  • Cost of chicken = Php. 120, amount of chicken = y kg
  • Budget = at most Php. 1200

a) <u>Required inequality (not a system as only one condition is given):</u>

  • 60x + 120y ≤ 1200

<u>Simplified:</u>

  • x + 2y ≤ 20
  • <em>The graph is attached</em>

b) <u>Verify ordered pair (10, 7):</u>

  • 10 + 2*7 ≤ 20
  • 24 ≤ 20

False inequality, so this pair is out of solution set

In a class in which the final course grade depends entirely on the average of four equally weighted 100-point tests,
MAVERICK [17]

Answer:

  [8, 44]

Step-by-step explanation:

The average of equally-weighted values is their sum divided by their number.

<h3>Setup</h3>

For some fourth test score x, Paul wants an average between 70 and 79. This gives rise to the inequality ...

  70 ≤ (91 +88 +93 +x)/4 ≤ 79

<h3>Solution</h3>

Multiplying by 4, we have ...

  280 ≤ 272 +x ≤ 316

  8 ≤ x ≤ 44 . . . . . . . . . . subtract 272

Paul will get a C if his fourth test score is in the interval [8, 44].
