Answer:
6 ft long
Step-by-step explanation:
If your rope is 24 ft long, then split it into 2.
Then each is 12 ft long
Split one of the 12 ft peices in half
SO,... its 6 ft for one rope, and 18 ft for the other.
Hope this helps!
Answer:
23/2
Step-by-step explanation:
If x = 5,
y = 5 + 1 = 6
(5+6) + 1/2 = 11 + 1/2 = 23/2
It would cost 5.38 to buy 2 pounds of cheese.
X + y = 180
x = 4y
Plug that in and you get: 4y + y = 180
5y = 180
y = 36
If you want the larger angle, simply plug in y to x = 4y
So: x = 4(36) = 144
The smaller angle is 36 degrees, and the larger angle is 144 degrees.
