Answer:

And if we solve for y we got:


And replacing we got:

And we got:

And for x we got:

So then the length would be 76 and the width we got 12.5
Step-by-step explanation:
For this case we have a rectangle. The perimeter is given by:

Where x represent the length and y the the width. We can set the following conditions:

And if we replace the conditions we got:

And if we solve for y we got:


And replacing we got:

And we got:

And for x we got:

So then the length would be 76 and the width we got 12.5
1 dozen = 12 eggs
Multiply 12 by 3 1/2:
12 * 3 1/2 = 42 total eggs.
Answer:
98
Step-by-step explanation:
So we have the two functions:

And we want to find the value of r(g(4)).
To do so, first find the value of g(4):

Multiply:

Subtract:

Now, substitute this into r(g(4)):

And substitute this value into r(x):

Square:

Subtract:

Therefore:

Answer:
<h2><u><em>
2/7</em></u></h2>
Step-by-step explanation:
I answer for what I understand, the question is not clear.
2 divided by what times what equals 7
2 : x = 7
x = -2/-7
x = 2/7
-------------
check
2 : 2/7 = 7
2 * 7/2 = 7
7 = 7
the answer is good
