Akimi4 [234]
Don’t know 1 but 2 is J or 3 because it’s y=mc+b and m=slope and parallel lines have the same slope and 3 is B or -4/5 because if you use the slope formula ( y2-y1/x2-x1) you get the slope (-4/5) and parallel lines have the same slope.

Order these numbers from least to greatest.<br> 2.9, 2.207, 3.76, 2.27
Lelu [443]

Answer:

From least to greatest, the order would go: 2.207, 2.27, 2.9, 3.76.

Step-by-step explanation:

To find the least greatest number, we have to look at each digit. In this number sequence, the least greatest number is a 2 for the single digit. With those 2s, 2.2 is the lowest out of them. And out of the 2.2s, the 2.207 is smaller than the 2.27. The 2.27 is the next number, then the 2.9 and then the 3.76.

Hope this helps! :)
