45/-3=-15
Step-by-step explanation:
A negative integer is a negative whole number that is the opposite of a counting number. It is simply an integer less than 0.
The correct answer is 0.739 You are rounding to 3 decimal places not 4 :D
0.92
Step-by-step explanation:
There are 4 cards in a deck of 52 cards that has a face value of 3. That means that the other 48 cards don't have a face value of 3. Therefore, the probability of picking a card of this deck that doesn't have a face value of 3 is

53) Vertical angles are congruent, so 
54)
and
are supplementary, so 
55) Because vertical angles are congruent,
. Now, because DR bisects
, this means 
56) This is a geometric sequence where the next term is obtained by multiplying the previous term by -2, so the next two numbers are 16, -32
Answer:
540
Step-by-step explanation:
Amount of antifreeze in the 90% solution + amount of antifreeze in the 20% solution = amount of antifreeze in the 80% solution
0.90 x + 0.20 (90) = 0.80 (x + 90)
0.90 x + 18 = 0.80 x + 72
0.10 x = 54
x = 540
You need 540 gallons of 90% antifreeze solution.
