Multiplicative inverse is a number with which if you multiply you get 1.
Hence 5/3 is the multiplicative inverse of 3/5
Since 3/5×5/3=1
Answer:
Step-by-step explanation: 1/9X ⅝ + (½)³ = 0.19
Answer:

Step-by-step explanation:
put them both in exponential form and then since they are both base 6, you can add the exponents.

Simple actually. The 1000 is the starting price the -20 is the losing of value per week and the w stands for the number of weeks.
Answer:
They say that the sum of the two numbers (x and y) is 64, so we can write our first equation by adding them and setting that sum equal to 64:
x + y = 64
The question also tells us that their difference is 14. Similarly to before, we'll just subtract the two numbers and set that difference equal to 14:
x - y = 14
Now from here, you know how to continue with substitution to find the values for x and y. Just remember when you get a word problem to break it down and look for key words like sum, difference, or product, and from there you'll be able to build your system of equations.
