Answer:
38%
Step-by-step explanation:
$600 is 100%
$60 is 10%
$6 is 1%
3 60s go into 228 with 48 still left.
6 times 8 is 48.
So its 38%.
Answer:
BK=39/7
Step-by-step explanation:
because NQZ~CBK
so BK/QZ = TZ/KF
(4x+1)/(2x+7) = 27/45 = 3/5
5(4x+1) = 3(2x+7)
20x + 5 = 6x + 21
14x = 16
x = 8/7
=> BK = 4(8/7)+1 = 39/7
I'm not sure what some of the ordered pairs are in what you wrote, but a function is when each input has one output. So, for every x there is one y. The x values can not repeat. So, remove one of two ordered pairs where the x value is repeating.
It would be, -14 x 12 which is -168 then / means divide so -168 divided by -6 equals -174. Your final answer is -174
