To estimate you round the numbers to the nearest whole number
9.7 you round up to 10
3.3 you round down to 3
so 10x3= 30
Well, 15% of 60 is 9 so now you have to create a model :)
I don't know. Use a calculator
Given:
The sequence is defined as "triple v, then subtract 7 from the result".
To find:
The expression for the given sequence.
Solution:
Triple v means 3 times of v, i.e., 3v.
So, the result is 3v.
Then subtract 7 from the result. So, the expression for the sequence is

Therefore, the required expression is
.
The correct answer is B. x is greater than -2.
