Answer: w=-6/14
Step-by-step explanation:
First you are going to put one equation on top of the other and subtract. Then you will use your new equation to combing like terms then divide your end result by your w value and make an improper fraction.
Answer:
B
Step-by-step explanation:
This is the difference of perfect squares, which follows a pattern of
(A+B)(A-B)
We have 64, which is 8-squared,
we have A squared, which is A squared ( :/ )
we have 81, which is 9-squared, and
we have B-squared, which is B squared.
We can factor this then following the pattern into:
(8A+9B)(8A-9B)
Choice B only matches one of our binomials.

Answer:
Sydney is 45
Step-by-step explanation:
Let s represent Sydney's age. Then Devaughn's age is (s-14). The total of their ages is ...
s +(s -14) = 76
2s = 90 . . . . . . simplify, add 14
s = 45 . . . . . . . divide by 2
Sydney's age is 45.
___
<em>Check</em>
Devaughn's age is 45 -14 = 31. Their age total is 45 +31 = 76, as required.
