9 million (Number of "Confession" sold) 4.97 million (Number of "Emancipation" sold)
problems setting the equations up? or solving the equations? or both? or are you just looking for the answer?
ok, pick one album and call it X... say Confession and label the other one Y
the sum of the sales was 13.97... of X and Y.... can you set up this equation?
what do you do to get a sum?
@Chrisblendz Can you at least give it a try!
when you sum a list of numbers, what do you do to get the total?
All you do is step by step! What is Sum?
Suppose you shop for 2 hats red and blue. How do you find out total?
Suppose red hat and blue hat are red r and blue b is
What you do with AND
x, y or r, b are operands What kind of operation to connect them together?
Yes, now we want total, so you should choose exactly one operation!
ok it should be *
Now your first rule to memorize TOTAL means ADDITION!
oh yeah that is right
x + y= 13.97
Since "The sum of these two albums was 13.97 " Can you write the expression for me. Suppose M is Emancipation and C is Confession:
m + c=13.97
It's crystal clear with SUM now :)
yes thank you for taking the time to help. :)
Since we have 2 variables m and c => We need 2 equations to solve!
Can you express "twice the amount of The Emancipation "
Write it down for me, will you?
wouldn't it be that same as sum?
What operation is it?
TWICE = DOUBLE => what operation?
Yep, so twice Emancipation means ??
Mutiply what with what?
m and c
Twice means double. What number is it?
"twice the amount of The Emancipation " = 2 * M
Is it ok?
"less than twice Emancipation " What operation for LESS?
@Chrisblendz do you follow me?
Yep, so " 0.94 million copies less than .." is
