Answer:
Step-by-step explanation:
Any number equal to or greater than 20 is a solution. 22 would be a solution.
N - the number
14 + n = 17 |subtract 14 from both sides
n = 3
Steve payed $4 in tax because 10% of 40 is 4. Steve payed $44 in total because 4+40=44.
Answer:
x - 6
Step-by-step explanation:
(4x2 + x - 5) - (5x2 - 1)
According to the order of operations, parenthesis come first so we will solve what is in the parenthesis first.
Then we do the multiplication because it comes before addition and subtraction.
4x2 = 8
Now we have 8 + x - 5
Combine like terms and 8-5=3 so we have 3 + x
Now for the second one.
5x2=10
10-1=9
Subtracting this from the first expression we have:
3+x-9 =
x - 6
