Answer:
x= 3
y = 0
Step-by-step explanation:
•Add the two equations to cancel out +6x and -6x
•Find the value of y
•Substitute the value of y into equation 1 to find the value of x.
Hope I was able to help you:)
Hello,
I hope so far you and your family are staying safe and healthy!
We need to solve this step by step.
The college student has $700 in their account. But then she spends $165 on books from that money. So we need to Subtract that.
700 - 165 =535
However, later on, she deposits $190 to the same account. So we need to take the remain we had and add it to the new amount.
535 + 190 = 725
Thus,
There are $725 in the account.
I wish you all the best!

8.125
Step-by-step explanation:
16.25*0.50=8.125
As a rule the product of an ODD number of NEGATIVE SIGNS is always NEGATIVE
An the product of an EVEN number of NEGATIVE SIGNS is always POSITIVE
Then the following statement is the right one:
Negative, because the product (-7)(-2) is positive, and the product (-5)(1) is negative and the product of a positive and a negative number is negative
You roll a die with the sample space S = {1, 2, 3, 4, 5, 6}. You define A as {1 ,4, 6}, B as {1, 3, 4, 5, 6}, C as {1, 5}, and D

Answer:
Step-by-step explanation:
Recall that two events A,B are called mutually exclusive if and only if 
(their intersection is empty). They are exhaustive if they are mutually exclusive and their union is the sample space.
Based on this
a) Note that 
, so they are not mutually exclusive nor exhaustive.
b) 
so they are not mutually exclusive nor exhaustive.
c) 
, so they are mutually exclusive. Note that 
. Then they are exhaustive.
d) 
, so they are not mutually exclusive nor exhaustive.
