X = 6 if you use the above equality
Answer:
$27.90
Step-by-step explanation:
Due the Laura and her sister being 2 people, we will be dividing the total by 2.
So,
55.80 ÷ 2 = $27.90
Both Laura and her sister will be paying $27.90 to split the amount evenly.
You would use the volume of a cone formula ((1/3)(pi)(r^2)h) so it would be (1/3)(pi)(7^2)(24). That simplified to 392(pi) units^3. So the answer is c
7/9 = 42/54...when 42/54 reduces, it becomes 7/9...so this is proportional because proportions are nothing but equivalent fractions.
u could also check it this way...
12/21 = 15/24
cross multiply
(21)(15) = (12)(24)
315 = 288.....these do not equal and are therefore, not proportionate
440/4 = 300/3
110 = 100....not equal, so not proportionate
120/5 = 88/4
24 = 22.....not proportionate
66/82 = 99/123
0.804 = 0.804.......these are proportional
68/172 = 43/123
0.395 = 0.349......nope, not proportional
You simply do 973-449 to get 524 jars of strawberry jelly
