They have some of the same numbers
To find 29/9 as a mixed number you need to find out how many times does 9 fit in 29
9
18
27
36
We see that it fits 3 time 3 is your whole #
We also see that 29 - 27 = 3 so you write like this:
3 3/9
The denominator of the original fraction does change
I got 35 hours. You can solve by doing 10x+125=7x+230.
Expanded form means 3x3x3
As a power means 3 to the 3rd power (exponent of 3)
Value is 27 units cubed.
Answer:
Step-by-step explanation:
We have the polynomial
( 1 )
To solve this problem we have to take into account that only we can sum term with the same order in the variable. We have the polynomials

we can note (by summing term by term) that only the sum of the first and the fourth equation correspond to the given polynomial ( 1 ) of the problem. If we organize these polynomials (that is, write the equation down in a form where higher order appears first ) we have
and if we sum we obtain

that is what we was looking for
I hope this is useful for you
