The inequality sign can be used when referring to two quantities that are not the same size.
<h3>What is an inequality?</h3>
An inequality is used to express a condition whereby the two quantities are not the same.
For instance, if we have the same number of students inside and outside a classroom, we can use the equality sign. In a case where we do not have the same number of students inside and outside the classroom, we can use the inequality sign.

Answer: b I think
Step-by-step explanation:
I'll just do red for now, but if you're very desperate I guess I'll help with a few more lol. It's just a lot of typing and my computer is at 6% :)
RATIO:
Ratios are another way of comparing things. It's almost like a fraction, except that it can look like x:y.
I'm guessing you're comparing all of the reds to the total amount, which should be 39. Put 5 in for x and 39 for y to make it look like 5:39.
DECIMAL:
Oh decimals are so fun...
Just divide 39 by 5. The answer to red's decimal is 7.8.
PERCENTAGE:
Percentage can come a little bit confusing to some people, so I'll explain this the best I can.
Basically, all you have to do to find it is divide the number you're making into a percentage by the total amount, then multiply it.
5/39 x 100
0.1282051282 x 100
12.8205128205
I'm going to the nearest hundredth which is 12.82.
Your percentage is %12.82
(If you're rounding to the nearest whole number, it'll be %13)
THEORETICAL:
For this simplify your ratio. 5/39 cannot simplify, so just leave it as 3/39.
Sorry, sometimes I come out a little confusing, so just try not to think too hard about what I'm trying to say if you're confused more lol. Anyway my computer is going to die so I'll go now :)
Answer:
18 meters by 9 meters (or 9 meters by 18 meters)
Step-by-step explanation:
lets say the dimensions are x and y. we have x*y=162, and 2x+2y=54. from the second equation we have x+y=27 so y=27-x. plug this into the first equation to get x(27-x)=162 or -x^2 + 27x = 162. x^2 - 27x + 162 = 0. simplify to get (x-18)(x-9)=0. so x=18 or x=9. when x=18, y=9, when x=9, y=18 so the dimensions are 18 by 9 meters
Your greatest factor would be 9a
