Perform the multiplication as you would for whole numbers.
When you're done, count the number of digits to the right of the decimal point in each factor and add the result.
Place the decimal point in your answer so that your answer has the same number of digits after the decimal point.
Subtract 81 from both sides and it gives you m=9 which is the answer
Answer:
3966
Step-by-step explanation:
Use order of operations to solve this problem:
- Parentheses
- Exponents
- Multiply (Left to right)
- Divide (Left to right)
- Addition
- Subraction
In your case, there are no parentheses or exponents, so we can skip right the the multiply and divide step. The first multiplication is 98*63=6174. The next step is to do 32*69=2208. Then you minus 6174-2208=3966.
Hope this helps!
