Well, this could be a "hecto" but in practice it's not really used. If you want to use it, you would speak of "hectometers".
if your question would be 1000 times larger, then it would be "kilo" and this one is actually widely used.
First, let's use distributive property and expand this equation:
<span>0.25 (y-4)+0.07=0.22y-0.05 (60)
</span>0.25y - 1 + 0.07= 0.22y - 3
Now, isolate the values of y and solve!
0.25y - 1 + 0.07= 0.22y - 3
0.25y - 0.22y = 1 - 0.07 - 3
0.03y = -2.07
y = -69
Hope this helps!

Answer c or $31.08 is correct:)
sqrt (100) is a rational number
10*10 = 100 (-10)*(-10) =100
sqrt(100)
=-10, 10
these are rational numbers
