Answer:
First option: 2
Step-by-step explanation:
Check each answer:
8 < x(7-x)
8 < 2(7-2)
8 < 2(5)
8 < 10
True
8 < x(7-x)
8 < 8(7-8)
8 < 8(-1)
8 < -8
False
8 < x(7-x)
8 < -1(7-(-1))
8 < -1(7+1)
8 < -1(8)
8 < -8
False
8 < x(7-x)
8 < 0(7-0)
8 < 0
False
Therefore, 2 is the only correct solution out of the given answer choices.
If there are two cups in a pint, two pints in a quart, and four quarts in a gallon that means that there are 16 cups in a gallon. then, in order to convert, all you do is divide 152/16. when you divide this out, you get 9.5 gallons
5(2x-8)=90
10x-40=90
add 40 to both sides
10x=130
divide 130 by 10
and the answer Is x=13
Answer:
591.1
Step-by-step explanation:
V=πr2h/3 v=π*8.4*2*8/3
v= volume = 591.1
h= Hight = 8
r= radius = 8.4
