Answer:
(a) x = 3
(b) y = 6
(c) false/not true
(d) x = 5
Step-by-step explanation:
(A) 2 + x = 5 You would subtract the 2 from both sides which gives you x = 3
(B) 8y = 48 You would divide 8 from both sides which is 6 so y = 6
(C) 23 = 26 That is not true because 23 does not equal 26
(D) -7x - 3x + 2 = -8x - 8 First simplify the equation; -10x + 2 = -8x - 8. Next, you want to subtract 2 from both sides which gives us -10x = -8x - 10. Now you want to add 8x to both sides which is -2x = -10. And now you just divide -2 on both sides which gives us the answer 5. So, x = 5. I hope this helps. Let me know if one of the answers are incorrect.

Hi,
The answer is 8(6/9) = 6(8/9) as both are equal to 48/9 = 16/3
Hope this helps! If you’d like further explanation please let me know.
Problem 4
a)
MR = AG is a true statement because MARG is an isosceles trapezoid. The diagonals of any isosceles trapezoid are always the same length.
-------------------------
b)
MA = GR is false. Parallel sides in a trapezoid are never congruent (otherwise you'll have a parallelogram).
-------------------------
c)
MR and AG do NOT bisect each other. The diagonals bisect each other only if you had a parallelogram.
=================================================
Problem 5
a)
LC = AJ (nonparallel sides of isosceles trapezoid are always the same length)
x^2 = 25
x = sqrt(25)
<h3>x = 5</h3>
-------------------------
b)
LU = 25
UC = 25 because point U cuts LC in half
LC = LU+UC = 25+25 = 50
AJ = LC = 50 (nonparallel sides of isosceles trapezoid are always the same length)
AS = (1/2)*AJ
AS = (1/2)*50
<h3>AS = 25</h3>
-------------------------
c)
angle LCA = 71
angle CAJ = 71 (base angles of isosceles trapezoid are always congruent)
(angleAJL)+(angleCAJ) = 180
(angleAJL)+(71) = 180
angle AJL = 180-71
<h3>angle AJL = 109 </h3>
