D) 8.17 x 10^8
910000000 - 93000000 = 817000000
817000000 ---> 8.17 x 10^8
Answer:

Step-by-step explanation:
we know that
To find out how much solution the scientist used for the experiment multiply 3/4 by 1/6
so

simplify

Answer:
1)monomial
2)monomial
explanation:
as both polynomials have one term,it is considered as monomial
Hope this makes sense! It was too hard to type out lol. The one on the left is how it is solved the and one on the right kinda explains how I got the equation.
A mixed number is an integer and a fraction that is less than one (remember that x/x = 1.)
To simplify 25/10, calculate how many times 10 goes into 25 by dividing 25 by 10. The answer is 2 with a remainder of 5 (10 x 2 = 20, 25-20 = 5).
The mixed number is 2 and 5/10, which simplifies to 2 1/2.
