Looks good.Johnx said:Ann had some stickers. She gave y stickers to each of her 7 friend and had 12 stickers left.
a) Find the number of stickers Ann had at first in terms of y.
my answer: 7y + 12b) Each friend received 9 stickers. How many stickers did Ann have at first?
my answer: 7*9 + 12 = 75
Finding the number of stickers Ann had at first in terms of y means expressing the initial number of stickers she had in relation to a variable y, rather than a specific number.
Finding the number of stickers Ann had at first in terms of y can be useful in situations where the initial number of stickers may change or vary, and you want to express it in a more general form.
To find the number of stickers Ann had at first in terms of y, you would set up a mathematical equation or expression that relates the initial number of stickers to the variable y. This could involve using known information or given conditions in the problem.
Sure, for example, if Ann had y + 5 stickers at first and then gave away 3 stickers, the number of stickers she had at first in terms of y would be y + 5 - 3, or y + 2.
Finding the number of stickers Ann had at first in terms of y can be useful in scientific experiments or studies where the initial number of objects or substances is unknown or may vary. It allows for a more general representation of the initial conditions and can help in analyzing the results of the experiment.
