Answer:
x = 152/5 or x = 30.4 decimal
Step-by-step explanation:
Solve for x:
5 x - 152 = 0
Add 152 to both sides:
5 x + (152 - 152) = 152
152 - 152 = 0:
5 x = 152
Divide both sides of 5 x = 152 by 5:
(5 x)/5 = 152/5
5/5 = 1:
Answer: x = 152/5
Answer:
It will take 1.5 hours to paint the room together
Step-by-step explanation:
Martha can paint a room in 2 hours. Jamie can paint the same room in 6 hours.
Work done by Martha in 1 hour =
Work done by Jamie in 1 hour =
Work one together in 1 hour =
Now take common denominator to add both fractions
LCD = 6, Multiply the first fraction by 3
Now add the numerators
To find total hours of painting together, we take reciprocal of 2/3
Time taken to paint together =
It will take 1.5 hours to paint the room together
Answer:
<em>The probability that the outcome will be heads = 1/2</em>
Step-by-step explanation:
Sample of Total outcome: HHH THH HHT HTT THH TTH TTH TTT
Possible outcome of heads = more than one head = HHH THH HHT THH
Where H = head, T = tail.
Probability = n(possible outcome)/n(total outcome)
n(possible outcome) = 4
n( total outcome) = 8
Therefore,
Probability = 4/8.
<em>Probability = 1/2</em>
<em>Thus The probability that the outcome will be heads = 1/2</em>
