Square x first then add x then subtract by 2
Given expression : 12.3 + 6 (n - 0.5)
Step 1 : substitute n = 3.7
12.3 + 6 (3.7 - 0.5)
Step 2 : Simplify the parenthesis
12.3 + 6 (3.2 )
Step 3 : Do the multiplication and open the parenthesis
12.3 + 19.2
Step 4 : Add the two number
12.3 + 19.2 = 31.5
So the answer of the given expression when n = 3.7 is 31.5
Answer:
First, identify your variables:
Let x = number of men in attendance.
Let y = number of women in attendance.
x + y = 48.
and
y = 12 + x
sub the second equation in for y in the first equation:
x + (12 + x ) = 48.
12 + 2 x = 48
2 x = 36
x = 18
y = 12 + 18
y = 30
Please include the instructions. It appears that you want to find the value of m that makes m + 2 1/4 = 8 4/5, but you should state this explicitly.
Rewrite m + 2 1/4 = 8 4/5 as m + 2.25 = 8.80.
Subtr. 2.25 from both sides: m = 6.55 (answer)
This is also equal to 131/20 or 6 11/20.
Next time, would you please insert punctuation in your list of answers, to separate A from B, B from C, and so on.
