There correct answer to that question is 22.45
Answer:
−7r^(2)+12r+10x−18
Step-by-step explanation:
Grab the original equation: 10x+7r−r^(2)−6r^(2)−18+5r
For subtraction bits, treat them as negatives: 10x+7r+−r^(2)+−6r^(2)+−18+5r
Combine like terms: (−r^2+−6r^2)+(7r+5r)+(10x)+(−18)
Simplify that, and you get your final answer: −7r^(2)+12r+10x+−18
Answer:
The common factors of 64 and 100 are 4, 2, 1, intersecting the two sets above. In the intersection factors of 64 ∩ factors of 100 the greatest element is 4. Therefore, the greatest common factor of 64 and 100 is 4.

Answer:</h2><h2>The expected number of guests if the probability for a heavy snow fall is .40 = 98.4 </h2>
Step-by-step explanation:
The total number of guests for lodge to be full = 153
During heavy snow fall, the lodge will be full.
The expected number of guests during heavy snow fall = 153
During partial snow fall, the expected number of guests = 62
The probability of heavy snowfall = 0.4
The probability of partial snow fall = 1 - 0.4 = 0.6
The expected number of guests = [(0.4) (153)] + [(0.6) (62)]
= 61.2 + 37.2
= 98.4
14(x - 4) = 56
distribute the 14 through the parenthesis
14x - 56 = 56
add 56 to both sides
14x = 56 + 56
simplify
14x = 112
divide both sides by 14
x = 112/14
x = 8
