Answer:
F=70.7
Step-by-step explanation:
This is a simple substitution problem.
- The formula to change Fahrenheit to Celsius is
. - They give you C, so substitute it into the problem, which would give you
. - Simplify the right side of the equation by multiplying
by 21.5. - Now, add 32 to 38.7, which should have been your answer to the previous step.
- You should now have F= 70.7 as your answer.
Answer:
54.
Step-by-step explanation:
360/5 = 72
180-72=108
108/2= 54
Answer:
3x
Step-by-step explanation:
because that is the slope of the equation
Answer: The three odd integers are 11, 13 and 15.
Step-by-step explanation: The first point to note is that the three unknown numbers are consecutive, which means they follow one after the other. Also we are told that the numbers are consecutive “odd integers.” This also means there is a two-digit interval between one number and the next. Hence, if the first number is A, the next number will be A + 2, and the third number will be A + 2 + 2 (that is, A + 4)
At this point we can now derive the following expressions based on the information we have been given, which is;
The sum of the first and third (A + {A + 4} )equals the sum of the second and 13 ({A + 2} + 13). Therefore we can write this out as follows;
A + {A + 4} = {A + 2} + 13
After removing brackets we now have
A + A + 4 = A + 2 + 13
2A + 4 = A + 15
By collecting like terms we now have
2A - A = 15 - 4
(Remember that when a positive value crosses to the other side of the equation it becomes negative, and vice versa)
2A - A = 15 - 4
A = 11
Hence, the three consecutive integers are 11, 13 and 15.
