6 yards = 216 inches
make a proportion and cross multiply:
3/216 = 2/x
*cross multiply*
3x = 216(2)
x = 144 inches or 4 yards
-2 (3y + 5) = -4
3y + 5 = -4 / -2
3y + 5 = 2
3y = 2 - 5
3y = -3
y = -1
5y = (-1)*5
5y = -5
the answer is in your question lol.
its pi, which is
≈ 3.14 feet ^3
^^^ thats
ur answer
Answer:
The answer to your question is 1/8
Step-by-step explanation:
Data
Total volume = 1 gallon
Water drank by the hiker = 1/2
Water drank by each of his friends = ?
Process
1.- Calculate the water that he gave to his friends
Water gave to his friends = 1 - 1/2
= 1/2
2.- Calculate the amount of water each friend received.
1/2 ÷ 4 = 1/8
3.- Conclusion
Each of the friends received 1/8 of the gallon.
Step-by-step explanation:
a.
simply add both equations
x + y = 2
-3x - y = 5
----------------
-2x + 0 = 7
x = -7/2
x + y = 2
-7/2 + y = 2
y = 2 + 7/2 = 4/2 + 7/2 = 11/2
b.
1/2 x + 2y = -13
x - 4y = 8
first multiply the first equating by 2
x + 4y = -26
x - 4y = 8
--------------------
2x + 0 = -18
x = -18/2 = -9
x - 4y = 8
-9 - 4y = 8
-4y = 17
y = -17/4
