The answer is 13 1/3 or 13.333333333
8 x 5/3 = 13 1/3
19.625/3.14=6.25
Square root of 6.25= 2.5
2(2.5)3.14=
15.7
Step 1: Do the most inner parenthesis (7-2+3) = 5 + 3 = 8.
23+8-(14-8)
Step 2: Do the next parenthesis (14-8) = 6
23+8-6
23+8 = 31
31 - 6 = 25
So, 25 is your answer!
Order them from smallest to largest:
21, 24, 25, 26, 26, 31
mean: 25.5
add all the numbers up and divide them by 6.
median: 25.5
the number in between 25 & 26.
mode: 26
there are two 26’s in the pattern.
range: 21-31
We can set this problem up as an algebraic equation, which we can then solve to find our answer.
We start at -3. So we can start our equation with that:
However, this doesn't represent any change in temperature, just that we start at -3. To show change, we will use the variable 
, where stands for the number of hours. Each hour accounts for a change of -2.5 in degrees, meaning that we must multiply our by -2.5. We can now add this term into our equation:
We are trying to find when we will reach -18 degrees, so we will set our entire equation equal to -18 and solve:
It will take us 6 hours, or choice A.
