Step-by-step explanation:
Answer:
1.5 inches
Step-by-step explanation:
V=pir^2h
304=pi8^2h
pi64h=304
pih=4.75
h=1.51197195937
2x + 4y = 14
4x + y = 20......multiply by -4
----------------
2x + 4y = 14
-16x - 4y = -80 (result of multiplying by -4)
---------------add
-14x = -66....as u can see, ur y's cancel out
so ur answer is : 1st answer choice <==
** and just so u know, u could have multiplied the 1st equation by -2, and it would have cancelled out ur x's
1. -1
2. 1/2
not sure:
3. 7? —> 7x 1/7x=7x1= 7
4. 1/11?
33 percent.
7/21 = 0.3333333
