Answer:
x = 23
Step-by-step explanation:
Step 1: Write out equation
(58 - x) - (x) = 12
Step 2: Distribute negative
58 - x - x = 12
Step 3: Combine like terms
58 - 2x = 12
Step 4: Subtract 58 on both sides
-2x = -46
Step 5: Isolate <em>x</em> (divide both sides by -2)
x = 23
So i take "one hundred and twenty five " to be one full numer: 125
(my alternative understanding is that 100 is a full integer and only 25 thousands, but I don't think that's what the question meant)
thousands: this means that the number will have a form of
x.xxx
(because the smallest number of this form, 0.001 is one thousandth.
so we fill it in:
0.125
and that's the answer!!
(we fill right to left: so if the number was for exmple 25, we'd have to fill it in with 0:
0.025)
Step-by-step explanation:
-3¼ is greater than -4
