Answer: The common difference is 7, and the next two terms are 19 and 26.
Step-by-step explanation:
Between -9 and -2 there is +7, same with between -2 and 5, as well as 5 and 12. Adding 7 to 12 again gets 19, and adding 7 to 19 gets 26 as well for the next two terms.
Divide both sides by 2
a-c=2a
minus a fromboth sides
-c=a
Pretty sure it's the last one.
So out of 100 questioned 71 said Dallas Cowboys , that means 71% did , now we have to work out 71% of 1200 which is 852
That's not an equation, and it doesn't ask any question. As it stands, there's nothing to "solve".
You may have been given an assignment to "simplify" it ... make it prettier and less complicated.
In order to do that, let's pretend for a moment that you're asked to add up a list that says:
4 chickens + 6 cows + 5 cows + 6 cows
I'm convinced that you would have no trouble at all adding up this list. You would
know right away that you can add up all the cows into one number, but you can't
add cows to chickens. You would simplify the list,and it would become <em>
4 chickens + 17 cows</em>.
And now that you understand that, you're all ready to simplify the expression
in your question. Just add up all the 'y's into a single number, but you can't
add 'y's to 'x's.
When you're done, you have 4x + 17y, and you're done. That's all you can do with it.
