Answer:
a=5, b=-2
Step-by-step explanation:
If you simplify the equation, you get:
3ax +6 -4x -4b - 11x - 14 = 0 =>
3ax - 15x -4b -8 = 0
group together x's and constants:
(3a-15)x -8 -4b = 0
To make this 0 for all x, we have to find an a such that 3a-15 = 0 and b such that -8-4b = 0. this leads to a=5, b=-2
Answer is a if I am not mistaken
Answer:
Part A: Data summary is given in the table
Part B: out of the total 100 students, 15 students do not like either tennis or track
= 0.15
0.15 ×
= 15%
Part C:
Total no. of students that dislike track = 60
Total no. of students that dislike tennis = 40
According to the survey results, more people dislike track.
<span>We know that the cost of 5 kg of peanuts is $4.50, then the unit price per kilogram is
$4.50/5 kg = 0.90 $/kg
And the unit price per gram is:
$0.90 / kg * 1 kg/1000 = 0.0009 $/g or 0.09 cents/gram</span>
