3 0

Answer:

1st option

Step-by-step explanation:

To find (f ○ g)(x) substitute g(x) into f(x) , that is

f(\frac{1}{2x} )

= \frac{2}{\frac{1}{2x}+3 }

= \frac{2}{\frac{1+6x}{2x} }

= \frac{4x}{1+6x}

Solve, using the correct order of<br> operations, when x = 7 and y = 3<br> (x – 3) + 2y
sweet [91]

Answer:

10

Step-by-step explanation:

<em>Since it given that:</em>

<em>x = 7 and y = 3</em>

<em>We can substitute x and y:</em>

<em>(7-3) + 2(3)</em>

<em>7 - 3 = 4</em>

<em>4 + 2(3)</em>

<em>2(3) = 6</em>

<em>4 + 6 =10</em>

<em>Thus the answer is 10.</em>

STatiana [176]

Answer:

16.65 feet

Step-by-step explanation:

Okay, we have three boards that are each 6.85 feet long. If we cut 3.4 feet off one board, that board has:

6.85

−

3.4

=

3.45

feet left

If we cut off 0.5 feet off another board, that board has:

6.85

−

0.5

=

6.35

feet left

So, if we take our three new boards, the total length of plywood left is:

6.85

+

3.45

+

6.35

=

16.65

feet

Hope this helps!
