The answer to your question is b
2.8 is greater than 2.78 :)
If you look in the tens place and compare the two numbers, you will see that 8 is greater than 7. That’s how you know that 2.8 is greater than 2.78
Enter into calculator if possible, it is C by the way :DDDD
1) 2z= -6
divide both sides by 2
2z/2= -6/2
2 on the left cancels out
z= -3
2) y/-5= 20
multiply both sides by -5
(-5)(y/-5)= (-5)(20)
-5 on the left cancels out
y= -100
Hope this helps! :)
