Answer:
<h2><u><em>
the circumference of a circle is defined as:</em></u></h2><h2><u><em>
</em></u></h2><h2><u><em>
c = pi*diameter</em></u></h2><h2><u><em>
</em></u></h2><h2><u><em>
if we have x segments of length y, then we can fit:</em></u></h2><h2><u><em>
</em></u></h2><h2><u><em>
c/y = z</em></u></h2><h2><u><em>
</em></u></h2><h2><u><em>
we can fit z segments of size y on the circumference c</em></u></h2><h2><u><em>
</em></u></h2>
<u><em></em></u>
For ABC:
The interior angle of C is 180 - 142 = 38
The three interior angles add up to 180°
(2x - 15) + (x - 5) + 38 = 180
3x - 20 + 38 = 180
3x + 18 = 180
3x = 162
x = 54
The measure of angle ABC = x - 5 = 54 - 5 = 49
For JKL:
The interior angle of L is 180 - 100 = 80°
The 3 interior angles add up to 180°
(2x + 27) + (2x - 11) + 80 = 180
4x + 16 + 80 = 180
4x + 96 = 180
4x = 84
x = 21
The measure of angle JKL is 2x - 11 = 2(21) - 11 = 42 - 11 = 31°
(4/5)*what = (2/3)
Multiply by 5/4
.. what = (2/3)*(5/4)
.. what = 5/6

Answer:
B, C, E
Step-by-step explanation:
Distributing the minus sign in the given expression results in ...
6x +1 -3x -(-1)
6x +1 -3 +1 . . . . simplify
The two expressions that show the constant terms as +1 - 1 are erroneous. The two constant terms are +1 -(-1) or +1 +1.
The correct expressions are the 2nd, 3rd, and 5th ones (b, c, e).
