Answer:
Step-by-step explanation:
29 5x+8+x+4=90
6x=78
x=13
30 3x-7+11x-1=90
14x=98
x=7
31 3x+x+8=180
4x=172
x=43
32 6x-1+5x-17=180
11x=198
x=18
If the slope of a line is m and slope of a line perpendicular to it is m2 the
m* m2 = -1.
Line t has slope 7/8 therefore line u must have a slope of -8/7.
4 of the original boards have a summed length of 20 units. 5 x 4 = 20.
Since 2/5 is left from each board, you simply add them until the 2's add to 20.
So, 2 x 10 = 20. Hence, there are 10 2/5 boards.
That's just 4 of the boards that the 2/5 make up, but that should also mean that there are 10 3/5 boards as well.
30/5 + 20/5 = 50/5
Reduction = 10
The carpenter started with 10 5/5 boards.
