Answer:
Number of coins.
Step-by-step explanation:
You mean quantity?
The amount of or number of items (in this case coins).
When it comes to measurement, the most accurate estimate would be the whole number. A ruler has calibrated marks. It would be easy to locate 25. But when it is located between 25 to 26, you would have to estimate the decimal points. Generally, calibration marks are up to the tenths digit. For further digits, that would only an estimation. So, the estimated digit in this problem is 3 in the hundredths place.
1x=-1
that means whererever you see x, you replace it with -1
x is a placeholder for an unknown number
so repolace it
-1+5=4
5-1=4
true
All you would have to do is look at the 2 in the place of the thousands which equals 2000, then look at the 2 that is in the place of the tens, which equals 20, so (this might get complicated) 2000/20 is... (If you need more help just tell me)
-2/3x+9=4/3x-3
+3 +3
-2/3x+12=4/3x
+2/3x +2/3x
12=6/3x
12=2x
x=6
x=6
