ax is multiplication of x by 'a'. a+x is addition. They are different operations.

x/(1/3) is not the same as x(1/3). Multiplication and division are different operations.

A line segment on a number line has its endpoints at -9 and 6. Find the coordinate of the midpoint of the segment.. . A. 1.5. *

Lyrx [107]

By definition, the midpoint is given by:
$m = (\frac{x1+x2}{2}, \frac{y1+y2}{2})$

Part A:
For the line segment we have:
$m = \frac{-9+6}{2}$
$m= \frac{-3}{2}$
$m = -1.5$
Answer:
the coordinate of the midpoint of the segment is:
B. -1.5

Part B:
For line segment HX we have:
$m = (\frac{-1+7}{2}, \frac{3-1}{2})$
$m = (\frac{6}{2}, \frac{2}{2})$
$m = (3,1)$
Answer:
the coordinates of the midpoint of the segment is:
A. (3,1)

You bike for 2 hours at a speed no faster than 17.6 mph. Write an inequality that represents the possible number of miles you bi

Whitepunk [10]

Total no. of hours you spent biking = 2 hours
the speed at which you rode your bike ≤ 17.6 mph
Now,
We have,
$speed = \frac{distance}{time}$

$17.6 = \frac{distance}{2}$

$17.6 *2= distance$

$35.2=distance$

So, you for given conditions, you can't travel more then 35.3 miles

So, the inequality for the given circumstances is:
x ≤ 35.2

Need help with this please

Crazy boy [7]

Answer:

1. 2(k + 3)

2. 3. 75 + k

Step-by-step explanation:

1. 2x + 6

Since, 2 is a common factor of 2 and 6, we can take that common outside.

So, 2x + 6 = 2(x + 3)

Note that in the initial expression, this 2 was distributed to arrive at 2x + 6.

2. (1.5 + k) + 2.25

This is simple addition. We can simply remove the brackets to have:

1.5 + k + 2.25

Since, the like terms can be added, we will have:

1.5 + 2. 25 + k

= 3. 75 + k
