Answer:
B) √58 > 6.85
Step-by-step explanation:
7^2 = 49
8^2 = 64
so √58 is between 7 and 8 ---> 7 < √58 < 8
so √58 > 6.85 is true
So, all you would do is use distribution.
For example: D is .5(x+3) = -3(x-.5)
you would do
.5 times x+3, which equals .5x+ 1.5
So, .5x+1.5=-3x+1.5
because -3*x-.5 is -3x+1.5.
Then, you would just get x by itself.
.5x+1.5=-3x+1.5
add 3 over to .5 = 3.5x;
subtract 1.5 over to 1.5 = 0
now you have 3.5x = 0
divide by 3.5 to get x by itself and you get zero.
x=0
When you substitute it in, you should have them both equal to each other. I hope this helps. :)
The answer is three and one over 3 or 3 1/3

Answer:
180 miles
Step-by-step explanation:
Don drove (50 mi/h)×(2 h) = 100 mi.
Frank drove (40 mi/h)×(2 h) = 80 mi.
Since they drove in opposite directions, the total distance between them is
100 mi +80 mi = 180 mi.
The <em><u>correct answer</u></em> is:
Without changing the span on the compass, place the compass point on one endpoint of the diameter and draw a full circle.
Explanation:
The steps to construct an inscribed equilateral triangle using the diameter are:
1. Place your compass point on the paper and draw a circle. Be sure to keep the compass set at the same width.
2. Using a straightedge, draw the diameter of the circle.
3. With the compass still set to the same width, place the compass point on one endpoint of the diameter and draw a full circle.
4. Draw segments connecting the points of intersection of the two circles and connecting each of these points to the opposite end of the diameter (the one <em>not</em> used as the center of the circle). This forms our triangle.
