Answer:
The Answer is 58.5 beats per minute. Have a Great Day!
Step-by-step explanation:
i know this because if you divide 78 by 4 you get 19.5 so all you need to do is multiply that by 3 and you get your answer
Answer:
1 AM = 58 Degrees
9 AM = 76 Degrees
Difference of temperate between the times:
18 Degrees
Divide every hour that passes by the total difference of temperate, which the hours are: 2, 3, 4, 5, 6, 7, 8, 9
18 / 8 = 2.25
Which means, the rate of change in degrees per hour is 2.25 degrees.
Step-by-step explanation:
Y - x = -13
-4x + 3y = -51
Use any of the equation to find the value of x or y. In this case, I'll use the 1st equation to find the value of y.
y - x = -13
y = x - 13
Substitute the value of y in the 2nd equation to find the value of x.
-14x + 3y = -51
-14x + 3(x-13) = -51
-14x + 3x - 39 = -51
-11x = -51 + 39
-11x = -12
x = 12/11 or 1 1/11
Substitute the value of x in any equation to find the value of y.
y = x - 13
y = 12/11 - 13
y = 12/11 - (13*11/11) *to get the common denominator
y = (12 - 143)/11 = -131/11 = 11 10/11
to check: x = 12/11 or 1 1/11 ; y = -131/11 or 11 10/11
y - x = -13
-131/11 - 12/11 = -13
(-131 - 12)/11 = -13
-143/11 = -13
-13 = -13
