Answer: 20
Step-by-step explanation:
x+y=5
x-y=4
---------
x+y=5
x=4+y
--------
(4+y)+y=5
4+y+y=5
4+2y=5
2y=1
y=0.5
x=4.5
---------
x²-y²=(4.5)²-(0.5)²=20.25-0.25=20
No, it is an irrational number. It repeats
No, it is an irrational number because it does not terminate/end
Lets say the number is 155:
100 + 50 + 5
one hundred and fifty-five
155
idk the last one tho
there should be only 3 ways, plz double check
7 hours X 60 minutes = 420 minutes
420 minutes + 20 minutes = 440 minutes
A must be parallel to b.
Proof:
∠3 = <span>∠13 (given)
</span>∠15 = <span>∠13 (vertically opposite angles are equal)
Since </span>∠13 = ∠3 and ∠13 = ∠15, ∠15 = <span>∠3
Then, a must be parallel to b (transverse line d cuts parallel lines producing converse alternate angles that are equal (ie </span>∠15 = <span>∠3))
</span>
