Answer:
5.85
Step-by-step explanation:
100%-> 6.50
100%-10% = 90 %
90%-> 6.50/100 x 90
=5.85
Answer: 3/25
because 6
The upside down U means intersection
A intersect B intersect C is where all 3 circles overlap.
Sum up all the numbers to get 50
6/50 in half is 3/25
9a + 5b + 5c = 9
Multiplying the whole equation by -2.
-18a - 10b - 10c = -18.
Hence, the answer is -18.
