<4 ≅ <1, 3 <≅ 2 Corresponding angles postulate
ΔACE ≈ ΔBCD Angle angle similarity postulate
(CB + BA)/CB = (CD + DE)/CD Substitution property of equality
I think it is 6 over 6 because it has a 6 for the denominator
10+ x/6 i believe this is the answer
If you need help with anything you can post it.
13x + 5y = 16
2x - 8y = 20
Multiply the equations;
13x + 5y = 16 [x2]
2x - 8y = 20 [x13]
26x + 20y = 32
26x - 104y = 260
Reverse the signs on one equation;
26x + 20y = 32
-26x + 104y = -260
'-26x' gets cancelled, leaving;
20y = 32
104y = -260
20y + 104y = 124y
32 - 260 = -228
124y = -228
y = -228 / 124
y = -1.84
Substitute in one equation and find 'x'.
Hope this helped! :)
