Three boards are placed end to end to make a walkway. The first board is 4 feet inches 10 long, the second board is 2 feet 11 in
Strike441 [17]

Answer:

12 ft 2 in.

Step-by-step explanation:

Conversion: 1 ft = 12 in.

Add the lengths of the boards.

4 ft 10 in. + 2 ft 11 in. + 4 ft 5 in. =

= 4 ft + 2 ft + 4 ft + 10 in. + 11 in. + 5 in.

= 10 ft + 26 in.

= 10 ft + 24 in. + 2 in.

Since 1 ft = 12 in., then 24 in. = 2 ft.

= 10 ft + 2 ft  + 2 in.

= 12 ft 2 in.

What the length of segment LM
Nikolay [14]

Answer: LM = 23

Step-by-step explanation:

Solve the algebraic equations:

Line KN: (solve for x)

14x-3=25

move the 3 to the other side with addition

14x=28

divide by 14 to get x by itself

x=2

Now that we have x we can find line KL:

9(2)+5\\18+5\\23

So we now know that KL is 23 units. And we know that KL = LM

Which of these equations could represent the blue line?
belka [17]

Hello from MrBillDoesMath!


The first choice (y = 2x) is NOT the blue line because it has twice of the slope of the line y=x. That is,  for a given positive x value the graph of y= 2x  appears above the black line which is not the case for the blue line shown.

The second choice (y =.001x) is a possibility but the multiplier .001 is so small I think the graph of that line would be "close" to the x-axis. I don't think it's the blue line.

y = -x. Now here we can say NO!  That line goes through the origin all right but has a slope of -1 so is heading "downward" from left to right. That is not the blue line either.

Well, then, it seems that the last equation ( y = 1/2x) is the only remaining reasonable answer.


Regards,  MrB.
