Answer:
The solution will be negative.
Step-by-step explanation:
I'm not quite sure what sort of answer you're looking for though.
Answer:
x = 2y
x - 8 = y + 6
replace x by 2y in the second equation
2y - 8 = y + 6
y - 8 = 6
y = 14
x = 2*14 = 28
Kendra had $28 and Kareem had $14.
(amount raised) = $2 × (number of classmates)
Second question:
sum of all the interior angle 180*(8-2)=1080 degree
sum of one interior angle 1080/8=135 degree
