-21/2 which in decimals would be -10.5. The actual numbers would be -14 and -7 and the median
x is 53
angle PQD is equal to APQ. so its 62 degrees
PRC and PRD are supplement so their sum is 180.
PRD=115 PRC= 180 -115= 65
the sum of the angles of a triangle is equal to 180. so:

good luck
Answer:
x=1
Step-by-step explanation:
x+3x+5x+7x+...+49x=625
(1+3+5+7+...+49)x=625 (1)
now consider s= 1+3+5+7+...+49
a=1
d=3-1=2
l=49
l=a+(n-1)d
49=1+(n-1)2
49-1=(n-1)2
48/2=n-1
n-1=24
n=24+1=25
s=n/2*(a+l)
s=25/2(1+49)
x=25/2×50
s=25×25=625
from (1)
625 x=625
x=625/625=1
First of all, the square root of 28 is 5.3. That is because 5.3*5.3=28.09 but mainly just 28. So now that we know what the square root of 28 is now we can multiply it by 3.
5.3*3= 15.9
Your final answer is 15.9
That would be 15/80=3/16 so it would be 3/16 or unlikely because it is less than half of 16
