Table:
4 cups of water, 5 cups of flour.
9 cups of water, 10 cups of flour.
16 cups of water, 17 cups of flour.
29 cups of water, 30 cups of flour.
Equation:
f-1=w
Independent variable:
F
Dependent variable:
W
We want to find the value of the 8 in 281,480,100
Let's find the place value of each of the numbers:
2 - hundred millions
8 - ten millions
1 - millions
4 - hundred thousands
8 - ten thousands
0 - thousands
1 - hundreds
0 - tens
0 - ones
I see there are two 8's so I wouldn't be too sure of which value to find, but just in case, we have the chart made above for place values.
There is one 8 at the ten millions value.
There is one 8 at the ten thousands value.
Simply remember PEMDAS:
P = Parentheses
E = Exponents
M = Multiplication
D = Division
A = Addition
S = Subtraction
You perform these actions from left to right.
However in this case it is not possible for it to equal 60.
I believe its 80 if you derive it out, but there is no units of measurement.
