The expression used to find the amount Maxwell still owes on the skis is [350 - (110 + 30) ÷ 2]
An algebraic expression (or) a variable expression is a combination of terms by the operations such as addition, subtraction, multiplication, division, etc.
Given that, Maxwell bought a new pair of skis for $350. He put $110 down and received a students discount of $30. His mother gave him 1/2 of the balance for his birthday,
We need to find the expression that can be used to find the amount Maxwell still owes on the skis,
So, the total amount of skis = $350, he put down $110 also got $30 discount,
So, the amount = 350 - (110+30) also, his mother gave him 1/2 of the balance for his birthday.
So, the final amount is 350 - (110 + 30) ÷ 2
Hence, the expression used to find the amount Maxwell still owes on the skis is [350 - (110 + 30) ÷ 2]

Answer:
Maxwell bought a new pair of skis for $350. He put $110 down and received a students discount of $30. His mother gave him 1/2 of the balance for his birthday. Which of these expressions could be used to find the amount Maxwell still owes on the skis?
The value of unknown number is 7.
Here,
The expression is given as;
⇒ ( +4)+59=70
We have to find the unknown number.
What is Mathematical expression?
The combination of numbers and variables by using operations addition, subtraction, multiplication and division is called Mathematical expression.
Now,
Let the unknown number is x.
Then, The expression become;
( x + 4 ) + 59 = 70
Subtract 59 both side,
( x + 4 ) + 59 - 59 = 70 - 59
x + 4 = 11
Subtract 4 both side,
x + 4 - 4 = 11 - 4
x = 7
Hence, The value of unknown number is 7.
