Answer: The answer should be -40.
Step-by-step explanation: A product is the result of multiplication and in cases like this, "less than" points to the mathematical operation of subtraction.
So when you see product, you automatically know the problem deals with <em>multiplication</em>. When you see less than, you automatically know the problem deals with <em>subtraction</em>.
The translation of this problem is 8 · -4 = x, then x - 8 = a (aka the answer).
First step is to find x, then to find a.
Note that a positive times a negative will give you negative. 8 times 4 is 32, but since 4 is a negative number here, the answer would be -32.
From this we can conclude that x is -32.
8 · -4 = -32, then -32 - 8 = a
Final step is to find a, which would be the result of -32 - 8.
-32 - 8 is -40 (Note: a negative minus a positive is basically addition in negatives. For instance, if we did -2 - 2, it'll give us -4.).
a = -40
Your answer is -40.
Answer:
-4x + y + 6z
Step-by-step explanation:
Combine like terms (Terms with the same variable):
(2x + 5y - z) + (-6x - 4y + 7z)
Add straight across:
2x - 6x = -4x
5y - 4y = y
-z + 7z = 7z - z = 6z
-4x + y + 6z is your answer.

Answer:
The probability of selecting an odd number given that the chip is black is 0.454.
Step-by-step explanation:
First of all, the value of probability is always less than 1, so the following value of probabilities need to be corrected and are:
Probability of selecting a black chip with an odd number(A)=0.415
Probability of selecting a black chip(B)= 0.915
Probability of A given B is denoted by=P(A | B)
P(A|B) =P(A∩B)/P(B)
P(B)=0.915
P(A∩B)=0.415
P(A|B)=
P(A|B)=0.454
The probability of selecting an odd number given that the chip is black is 0.454.
