At the end of a snowstorm, Ellie had 16 inches of snow on her lawn. The temperature then increased and the snow began to melt at a constant rate of 1 inch per hour. Assuming no more snow was falling, how much snow would Ellie have on her lawn 4 hours after the snow began to melt? How much snow would Ellie have on her lawn after tt hours of snow melting?
Answer:
12 inches
Step-by-step explanation:
1 x 4 = 4
16 - 4 = 12
Snow after 4 hours: 16 Show after t hours: -1t
Step-by-step explanation:Snow after 4 hours:
starting amount = 16
melted snow= inches per hour×4
=1×4
=
4
final amount= starting amount−melted snow
= 16−4
=12
Snow after t hours:
starting amount= 16
melted snow= inches per hour×t
=1×t
=1t
final amount= starting amount−melted snow =16-1t

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!!
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

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