SInce you are spending 2 each day, you increase -2 dollars as each day passes.
So, the expression would be -2d+207.
Hope this helps!
This is the incomplete question.
I hope we need to find the remaining amount and choices must be given.
Hope this is your question, if not I think you will, still be able to
find an answer of your question based on this solution.
Since you are spending $2 each day.
So, in d days you will spend 2d.
You had $207. So, to get the amount of remaining amount we will subtract 2d from total amount 207.
Hence, remaining amount = $ ( 207 - 2d)
Question asked: You had $207, but you are spending $2 each day. Which algebraic expression describes this situation, where d represents the number of day?
Because u have $207 but u r spending $2 a day that is where the -2d comes in
let soccer = x and golf = y
1st equation: x + y = 125
2nd equation: x = y +45
replace x in the 1st equation with the 2nd one:
y + 45 + y = 125
2y + 45 = 125
subtract 45 from each side:
2y = 80
divide both sides by 2:
y = 80/2
y = 40
she plays golf for 40 minutes.
no because she plays soccer for 45 minutes longer than golf 40 +45 = 85 minutes, not 80 minutes.
