For, "x" greater than 34, the perimeter of the picture frame greater than 152 inches
<em><u>Solution:</u></em>
Let "x" be the width of the frame
<em><u>Given that, The length of a picture frame is 8 inches more than the width</u></em>
Therefore,
Length = width + 8
Length = x + 8
<em><u>The perimeter of rectangle is given by formula:</u></em>
Perimeter = 2(length + width)
Substituting the values we get,
Perimeter = 2(x + 8 + x)
Perimeter = 2(2x + 8)
Perimeter = 4x + 16
The perimeter of the picture frame greater than 152 inches
Perimeter > 152
Therefore, for, "x" greater than 34, the perimeter of the picture frame greater than 152 inches
They do all EXCEPT D, but the best answer is A because one can solve the system of equations this way
Let
x------> the number of multiple choice question
y------> the number of free response question
we know that
-----> equation A
-----> equation B
Substitute equation B in equation A
Find the value of x
therefore
the answer is
the number of multiple choice question are
the number of free response question are
The key to solving this problem is recognizing it is a proportion and can be solved using the technique called cross-multiplication. This m<span>eans that you are multiplying the numerator of each side by the denominator of the other side.</span>
You multiply the numerator of the first side by the denominator of the second and the denominator of the first by the numerator of the second.
Simplify.
Factor.
Set each factor equal to zero and solve for x.
Finally, you want to look at the original expression and make sure that these solutions don't violate any restrictions on division by zero.
For the right side, we see that
≠
, so
≠
. For the left side, we see that
≠
, so
<span>≠ </span>
. This means our solutions are valid.
x = -9/4, x = 1
Answer:
the opposite of an opposite is a positive number .
Step-by-step explanation:
fractions that are negative on a number line are proved to be on the exact spot but but on the opposite side of the number line.
