7 0

Answer:

$4\frac{1}{2}$

Step-by-step explanation:

This question is basically saying: what is half of 7, or what is 7 divided by 2?

Based on this, it can be written both of the ways as:

»» $\frac{1}{2}$ of 7 OR 7 ÷ 2

So, just solve using either one and you’ll get 4.5 or $4\frac{1}{2}$ . But since the question wants the answer to be a mixed number, then choose $4\frac{1}{2}$ .

Hope this helps! :)

Yes, i believe so because u can count back twice and u will get 5. You could al so do: 7-2=5. Hope this helps

67. The line contains the point (4,0) and is parallel to the line defined by 3x = 2y.

Answer:

$y=\frac{3}{2} x-6$

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form:

$y=mx+b$ where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)

Parallel lines will always have the same slope but different y-intercepts.

1) Determine the slope of the parallel line

Organize 3x = 2y into slope-intercept form. Why? So we can easily identify the slope, m.

$3x = 2y$

Switch the sides

$2y=3x$

Divide both sides by 2 to isolate y

$\frac{2y}{2} = \frac{3}{2} x\\y=\frac{3}{2} x$

Now that this equation is in slope-intercept form, we can easily identify that $\frac{3}{2}$ is in the place of m. Therefore, because parallel lines have the same slope, the parallel line we're solving for now will also have the slope $\frac{3}{2}$ . Plug this into $y=mx+b$ :
