Lindsey has 33 coins in her change purse that are either dimes or quarters. If y represents the number of quarters she has, write an expression in terms of y that describes the number of dimes?
number of quarters --- y
number of dimes ---- 33-y
y-33
Let's assume that Lindsey has y quarters.
Since Lindsey has a total of 33 coins, the number of dimes she has can be expressed as 33 - y.
Therefore, the expression in terms of y that describes the number of dimes Lindsey has is 33 - y.
To solve this problem, we need to understand the relationship between the number of quarters (y) and the number of dimes in Lindsey's change purse.
We know that Lindsey has a total of 33 coins, and the only coins she has are dimes and quarters. This means that the sum of the number of dimes and the number of quarters is equal to 33.
Since the number of quarters is represented by y, we can express the number of dimes in terms of y.
Let's assume that x represents the number of dimes.
The equation for the total number of coins can be written as:
x + y = 33
Now, to express the number of dimes (x) in terms of y, we can rearrange the equation as follows:
x = 33 - y
Therefore, the expression in terms of y that describes the number of dimes is 33 - y.
