Answer:
3x
Step-by-step explanation:
Its 3x because if you dont know the amount of months which is x and she buys 3 songs every month it equals 3x
One square grid has an area of 400.
Another square grid has an area of 256.
The area of the third grid can be:
(squares in third grid) + 256 = 400
OR
256 + 400 = (squares in third grid)
We get this by applying the Pythagorean theorem.
So, the squares in the third grid can either be 144 or 656. And we only have 144 as an option, so that is your answer.
Your final answer is D. 144.
Fraction of black pens = 2/ (2 + 5) = 2/7 answer
For this case we have the following interval:
The equivalent expression for this interval is given by:
Therefore, we have the following inequations:
From where, we can conclude:
All real numbers greater than -6 and less than 7
Answer:
An expression in words that describes the set of numbers given by the interval (-6, 7) is:
A. All real numbers greater than -6 and less than 7
Solve for q:
2 p - 1/q = r/q + 4
Bring 2 p - 1/q together using the common denominator q. Bring r/q + 4 together using the common denominator q:
(2 p q - 1)/q = (4 q + r)/q
Multiply both sides by q:
2 p q - 1 = 4 q + r
Subtract 4 q - 1 from both sides:
q (2 p - 4) = r + 1
Divide both sides by 2 p - 4:
Answer: q = (r + 1)/(2 p - 4)
