The expression is given by:
18+n
where n is a number.
We are asked to represent the given word phrase as a mathematical expression.
The word phrase is given as follows:
The sum of 18 and a number.
Let the unknown number be represented by a variable n.
Now, we know that the sum of 18 and n is such that both the terms 18 and n are separated by a addition sign.
Hence, the expression is: 18+n
Answer:
probably 57 will be the answer
6
Step-by-step explanation:
5% of 120 were late
= × 120
= 0.05 × 120
= 6
First break up 72 into
36 x 2 x -1
Then take the square root of 36
6 square root 2 x -1
Finally make square root -1 = i
6i square root 2 is your answer
