Answer:
X=39
Step-by-step explanation:
1/2×(4+8x)+22=180 (factor expression)
1/2×2(2+4x)+22=180. (Reduce)
(2+4x)+22=180 (rewrite expression)
2+4x+22=180 (calculate)
24+4x=180 (move constant to right)
4x=180-24 (calculate)
4x=156 (divide both sides)
X=39
Answer:
7 cups of flour
reason:
to find how much flour is needed, first you need to combine the two fractions.
to add the fractions, you first have to find a common denominator, which in this case is 15
multiply 1/5 by 3 to get 3/15, and 2/3 by 5 to get 10/15. combined, this is 13/15
since the answer is looking for the best estimate, you take the overall amount of flour, which would be 6 13/15, which is closer to 7 cups than 6
(I may be wrong this is just how I did it)
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>
