A. false. Even though 5 is usually greater than 2, in this case it is less because it is negative and positives are always greater than negatives.
B. true. Just like the last question, positives are always greater than negatives and even though 8 is usually greater than 3, in this case the 3 is a negative so it is less.
C. true. Think about which number is closer to the number line. When we are talking about negative numbers, the number closer to the number line is greater.
D. false. Same concept as the last question where -12 is closer to the number line than -12.5 so -12 is actually greater.
If you have any additional questions feel free to ask me or your teacher so you can really master what you're learning. :)
On A it would look like this -5 -4 -3 -2 -1 0 1 2 3 4 5 see how the 2 is above 0 and -5 is below 0 that means that 2 is higher up the number line than -5
On B same thing here -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 see how 3 is higher than -8
On C its -16 -15 -14 -13 -12 -11 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 so when there both a negative u want to look for the lowest number like -12 see how its closer to 0 than -15
On D -13 -12.5 -12 -11 see how -12.5 is just a bit higher than -12,-12, is the lower number or closer to 0
This is the concept of areas and circumference of the solid figures; The circumference of the cylinder whose radius is 4 m will be given by; C=2πr C=2*π*4 C=8π m=25.133 m
