Since x and y must be positive, 7x and 11y are positive either. That means 7x + 11y > 0. Then we would obtain N > 0 because 7x + 11y = N. That also means N must be positive. So if we set N to be zero or negative, there would be no solution. Thus, to produce an answer of No solution, the highest number N could be is 0.
Answer:
121 sq. in
Step-by-step Explanation
area of the frame = 48 square inches
if is the side length of the square, then ( + 2) is the side length of the square after the frame has been added.
the area of the picture + the frame is:
( + 2) ( + 2)
the area of just the frame is given by ( + 2) ( + 2) - x :
( + 2) ( + 2) - x =48
²+ x 2 + 2 x + 2 x 2-² = 48
² + 2 + 2 + 4-² = 48
4 + 4 = 48
then subtract 4 from both sides:
4x = 44
and divide both sides by 4:
x = 11
the area of the square is 11 (11) = 121.
i think this is correct?
hope this helps
Answer:
I don't know this exactly, but I'll give it my best go!
We can get the answer by answering questions we know are true and eliminating the ones we don't.
E: Experimental probability can be written in the form of a ratio.
- Any probability can be expressed by a ratio so this is true.
B: Experimental probability is the same as theoretical probability.
- They are two different 'types' of probability so this is most likely false.
A: Experimental probability has the total number of trials in the numerator and the number of times an event occurs in the denominator.
- I'm fairly certain that applies to theoretical probability, not experimental.
So that means the answers are most likely C, D, and E. If I was wrong let me know!

If y = 2, to find the value of y + 6, we need to substitute the value of y (2) into the expression y + 6. Substituting 2 for y, we get the equation 2 + 6. Since 2 + 6 = 8, that means that substituting y = 2 into the expression y + 6, we get 8.
