Answer:
there are 4/10 in 2/5 because if you divided it by 2 you get 2/5
Step-by-step explanation:
Answer: c=5.4
The two roots are 3/5 and 9/5
Step-by-step explanation:
assume 5x2−12x c=0 is supposed to be 5x^2 - 12x + c = 0
p = (12 + sqrt(144-20c))/10
q = (12 - sqrt(144-20c))/10
p-3q=0,
1.2 + 0.1sqrt(144-20c) +
-3.6 + 0.3sqrt(144-20c) = 0
-2.4 + 0.4sqrt(144-20c) +2.4 = 2.4
sqrt(144-20c) = 2.4/0.4 = 6
144-20c=36
144-36=20c
c = 108/20 = 5.4
5x^2-12x+5.4=0
x = 3/5 or x = 9/5
Answer:
A
Step-by-step explanation:
Notice how it points it out for the x coordinate, and the closed circle means that point is included, So it's the range of the smallest x coordinate to the greatest x coordinate.
Answer:
<em>b = 15</em>
Step-by-step explanation:
4(b + 5) = 3b + 35
Distribute:
4(b + 5)
4(b) = 4b
4(5) = 20
4b + 20 = 3b + 35
Combine like terms:
4b - 3b = 35 - 20
b = 15
