24 fossil kits with 10 samples would be the same as 30 fossil kits with 8 samples
Answer:
r=-2
Step-by-step explanation:
69=35-25r+4r-8 simplify
69=27-21r subtract 27 from both sides
42=-21r divide both sides by -21
r=-2
A = L * W
A = 45
L = 2W + 1
45 = W(2W + 1)
45 = 2W^2 + W
2W^2 + W - 45 = 0
(2W - 9)(W + 5) = 0
W + 5 = 0
W = -5...not this one because it is negative
2W - 9 = 0
2W = 9
W = 9/2
W = 4.5 <=== the width is 4.5 ft
L = 2W + 1
L = 2(4.5) + 1
L = 9 + 1
L = 10 <=== the length is 10 ft
Answer:
well, 5% of 31348 is 1567.4
That leaves her 3084.6 feet to go.
And as you know, time = distance/speed
