-2x + 6y = 6
y = 2x + 11

Answers

Answer:

(x, y) = (-6, -1)

Step-by-step explanation:

-2x + 6y = 6

y = 2x+11

By substituting the value of y (second equation) into the first equation, we get

-2x + 6(2x+11) = 6

-2x+12x+66 = 6

10x = -60

x = -6

So, y = -1

The temperature is changing at a constant rate of –0.75ºC per half hour. At 6:45 PM, the temperature was –4.6ºC. At what time was the temperature –2.1ºC? Be sure to include AM or PM in your answer.

Answers

Answer:

5:05 PM

Step-by-step explanation:

Each 30 minutes, we have a change of -0.75

So in an hour , we will have a change of -0.75 * 2 = -1.5

since -2.1 is greater than -4.6, this indicates that it was a time before 6:45 PM

so, let us find the temperature drop

That would be;

-2.1-(-4.6) = -2.1 + 4.6 = 2.5

So let us find the number of half hours

That would be;

2.5/0.75 = 3 1/3 half hours

3 half hours is 90 minutes

1/3 half hour is 1/3 * 30 = 10 minutes

Total number of minutes is;

90 + 10 = 100 minutes

So let us count 100 minutes before 6:45 PM

120 minutes before would be;

4:45 PM

but we want 100 minutes, so we have to add 20 minutes

That would be;

4:45 PM + 20 minutes

= 4:65 which is 5 : 05 PM

The student Advisory Council here at PC sells red and pink carnations every year for Valentine’s Day. The number of red carnations sold was 1 less than 3 times the number of pink carnations sold. Red carnations were sold for $0.60 each and Pink Carnations sold for $0.80 each. The club made $600.00. How many of each carnation were sold?


Please help!!

Answers

Answer:

The number of :

Red carnations sold = x = 692 carnations

Pink carnations sold = y = 231 carnations

Step-by-step explanation:

Let us represent

The number of :

Red carnations = x

Pink carnations = y

The Student Advisory Council here at PC sells red and pink carnations every year for Valentine's Day.

The number of red carnations sold was 1 less than 3 times the number of pink carnations sold.

x = 3y - 1 .....Equation 1

Red carnations were sold for $0.60 each and Pink Carnations sold for $0.80 each. The club made $600.00. .

$0.60 × x + 0.80 × y = $600

0.6x + 0.80y = 600...... Equation 2

Using substitution method:

Let us substitute, 3y - 1 for x in Equation 2

0.6(3y - 1) + 0.80y = 600

1.8y - 0.6 + 0.80y = 600

1.8y + 0.80y = 600 + 0.6

2.6y = 600.6

y = 600.6 ÷ 2.6

y = 231 carnations

Solving for x

x = 3y - 1 .....Equation 1

x = 3(231) - 1

x =693 − 1

x = 692 carnations

Therefore, The number of :

Red carnations = x = 692 carnations

Pink carnations = y = 231 carnations
