If ray EB bisects angle AEC, then m∠AEB=m∠BEC=4x+1.
Angles AEB, BEC and CED together form right angle AED, then
m∠AEB+m∠BEC+m∠CED=90°.
Therefore,
(4x+1)+(4x+1)+3x=90,
11x=90-2,
11x=88,
x=88:11,
x=8°.
Then m∠BEC=4x+1=4·8+1=33°.
Answer: x=8°, m∠BEC=33°.
Add them to cancel y
x+5y=8
<u>2x-5y=1 +</u>
3x+0y=9
3x=9
divide boht isdes by 3
x=3
sub back
x+5y=8
3+5y=8
minus 3
5y=5
divide 5
y=1

Please remove my answer, I answered the wrong thing!
31.35d + 0.15(275) </= 280
Step-by-step explanation:
(Daily cost x number of days) + (mileage cost x number of miles) is less than or equal to $280.
If they ask you to solve it next:
31.35d + 0.15(275) </= 280
31.35d + 41.25 </= 280
31.35d </= 238.75
d </= 7.615629998
