Isabella purchased 3 books from the book store. she now owns 11 books that she wants to read before the end of the year. if x represents the number of books she started with, which equation could be used to determine the value of x? a.) x-11=3 b.) x+11=3 c.) x+3=11 d.) x-3=11

Remark

The key phrases  are "she bought 3 books" and "she wants to read 11 before the end of the year."

So she had x and she added 3 to that x. The total is now 11. Eleven is on the right side of the equal sign.

So is it C or is it D?

D has the meaning of "She gave away 3 books." and is left with 11.

C <<<< Answer.

She started with x and added 3. She now has 11.

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
