This is the "commutative property of addition." The order in which you add numbers together doesn't matter, and doesn't change your final results.
<span>Yes, she is reasoning correct, because:
6 1/4 and 2 3/4 are mixed fractions and you can substract them as it shown below:
1. You must substract the fractional parts (</span>which are: 1/4 and 3/4) of the mixed fractions. You can notice that the have the same denominator "4", so you only need write this denominaro and substract the numerators:
= (1-3)/4=-2/4
When you simplify the result, you obtain:
=-1/2
Now, you must sum the integer parts:
6-2=4
Finally, you obtain:
4 -1/2
Answer:
πr²/4
Step-by-step explanation:
Area of a circle if πr²
so Area of a quarter of a circle (or 1/4 of a circle) = πr²÷4
The correct answer is < (B)
8+3 is 11
5*8 is 40 then take 2 away and you will get 38
11<38
Domain: [2,∞)
Range: [0, ∞)
hope it helps!
