Solve both equations for y:
Set the expressions equal to each other:
So, for every nonzero number a the system of equations has
one solution.
Since there is 16 cups in a US gallon, and there is 7 days in a week. First, you would multiply 1.5 times 7 getting 10.5 cups. But since that is not enough cups to be a gallon the division equation would look like this, 10.5/16 = ?. You can simplify it down to 5.25/8. Then, you get your answer of 0.65625 gallons.
Answer:
B
Step-by-step explanation:
We want to determine an equivalent trignometric identity with the given expression:
We can factor out a cos(x):
Recall from the Pythagorean Identity that:
Therefore:
Substitute:
Our answer is B.
Answer:
Step-by-step explanation:
Let x = the number of $20 bills.
Then x + 6 = the number of $5 bills and
20x + 5(x + 6) = 455
x = 17 = number of $20 bills
x + 6 = 17 + 6 = 23 = number of $5 bills
Check:
OK.
Answer:
Step-by-step explanation:
Given
Temperature = 12 degrees below 0
Required
Represent as an integer
12 degrees below 0 means that the temperature is less than 0.
This can then be expressed as:
Hence, the integer that represents this scenario is -12
