Answer: y=4
Step-by-step explanation:
9/4y-12=1/4y-4+12
+12. +12
9/4y=1/4y+8
-1/4y -1/4y
2y/2=8/2
y=4
Answer:
x = - 1
Step-by-step explanation:
therefore x is less than or equal to - 1
9/8 of a meter is 1 1/8 of a meter.
9/8 of a meter is also approximately 3.69 feet.
Vsphere=(4/3)pir^3
when we replace r with 2r
newvsphere=(4/3)pi(2r)^3
newvsphere=(4/3)pi8r^3
newvsphere=8((4/3)pir^3)
newvsphere=8(vsphere)
it's volume is multipliied by 8
that is choice C, because 2^3=8, it's vollume is 8 times original voluem
answer is C
