Answer:
82 is the median
Step-by-step explanation:
About the minus sign with 16, square root of -1 is an imaginary number i(iota). Also we know that square root of -16 will be multiplication of square root of -1 and square root of 16. So the final answer becomes, + or - 4i. Hope this helps
Answer:
w = 6
Step-by-step explanation:
Based on the midsegment theorem:
ST = 2(PR)
ST = w + 6
PR = w
Plug in the values into the equation
w + 6 = 2(w)
w + 6 = 2w
6 = 2w - w
6 = w
w = 6

Step-by-step explanation:
<span>-2z+10+7z=16z+7
first, group all numbers with the same variable. So it becomes:
</span>-2z+7z+10=16z+7
The right hand side has variable z, so move it to the left hand side. The sign will change if you move it to the other side. So it becomes:
-2z+7z-16z+10=7
We need to group those numbers with variable on one side and the integers alone on the other side. It becomes:
-2z+7z-16z=7-10
You can compute it directly, or if you still can't see it you may factorise it first:
(-2+7-16)z = 7-10
Then:
(-11)z = -3
Make z as a subject:
z= -3/-11
z= 3/11
The minus sign canceled out each other. Thus is becomes positive.
