Answer:
336 cm2
Step-by-step explanation:
k= 5.6
The problem statement tells us ...
8x = y +3
7x = y -4
Subtracting the second equation from the first gives ...
x = 7
Then ...
y = 7x +4 = 7·7 +4 = 53
There are 7 people, and 53 coins are required for purchase.
Answer
The median is 83
You must put the scores in order to find median.
48, 58, 65, 71, 77, 80, 83, 88, 92, 92, 93, 96, 97
Then you find the number that is in the exact middle of the list.
In this case the median (middle number) is 83
(7v +3 ) ( v + 4 )
7v^2+31v+12
(7v + ) ( v + )
12 = 1*12
2*6
3*4
7* 4 + 3 = 31
