A. 7 hours ago the temperature was 7 * 1,5 = 10,5 degrees more, so if now it's 0, then it was 10,5 degrees 7 hours ago.
b. in six hours it will be 6 * 1,5 = 9 degrees less, so if it's 0 now, then it will be -9 degrees in 6 hours.
c. the temperature was reading 6 degrees 4 hours ago because:
x * 1.5 = 6 / ÷1.5 (both sides)
x = 4
d. -8 is expected to be in 5 hours and 15 minutes because:
x * 1.5 = 8 / ÷1.5 (both sides)
x = 5 1/3
The answer is x - 5
To solve (x^2 - 8x + 15) /(x - 3) you factor the numerator and denominator and cancel the common factors.
Answer:
4/13
Step-by-step explanation:
Total number of marbles = 2+4+6+1=13
number of yellow = 4
yellow marble/total Number of marbles =4/13
Answer:

It is indeed justifiable that the operation involved in this task is combination because the arrangement of the assignments are not important. The combination may be solved directly from a scientific calculator using the function,
nCr
where in this item the value of n is 8 and that of r is 3. Substituting and solving the combination,
8C3 = 56
Therefore, there are exactly 56 combinations possible.
