Answer:
(7-5)
Step-by-step explanation:
According to PEMDAS, parenthesis go first. But there are two sets of parenthesis so the one inside the other goes first.
Next would be [3+(2*2)]
Then, [3+4]
Then, -8/1
Then, -3(7)
So the question would be 4-8-21
Which gives you -25 as an answer.
I realize that you weren't asking for the whole thing but maybe there are follow up questions.
Let x = the minutes that Tom has remaining before exceeding 500 minutes.
Because he has already used 230 minutes, the total minutes he has is
x + 230
We want this total to be less than or equal to 500 minutes.
Therefore
x + 230 ≤ 500
Answer: x + 230 ≤ 500
2.5 is already rounded to the nearest hundredth. S it cant be rounded again. Its already rounded by the nearest hundredth.
hope it helps!

So first you plug in (8,3) into their respective places, which makes it:
3= 5(8)-7
Solve
3 = 40-7
3 does not equal 33,
So the answer is no
