<em>The result is -13</em>
<h2>
Explanation:</h2><h2 />
Here we have the following addition problem:
So let's solve this step by step:
Step 1. Perform two plus two.
So:
Step 2. Perform the subtraction.
Since the sign (-) accompanies 17 which is greater than 4, then we perform the subtraction and add the sign (-) to the result. So:
<em>Finally, the result is -13</em>

Do you mean like 81/100 or like 81/1
Adding them up, we have 1/2+3/20+2/5+4/5. We can do a bit of guess and checking to see that 2, 5, and 20 go into 20. 20/2=10 and 20/5=4, so we multiply 1/2 by 10/10 and 2/5 and 4/5 by 4/4 to get 10/20+3/20+8/20+16/20= 37/20
Mean = Sum of points / Number of points ;
27 = ( 25 + 28 + 36 + 21 + 28 + 15 + 24 + 30 + x ) / 9 ;
243 = 207 + x ;
x = 36 is the number ;
Answer:
Step-by-step explanation:
We can use exponent rules to try and simplify this expression down.
Exponent rules tell us that .
This means that since we have the same base on both terms (7 and 7), we can add the exponents to get a simplified expression.
So our simplified expression is .
