Answer:
X = 48
Step-by-step explanation:
<em>to </em><em>find </em><em>X </em><em>we </em><em>must </em><em>first </em><em>make </em><em>it </em><em>the </em><em>subject </em><em>of</em><em> </em><em>the </em><em>formula</em><em>,</em><em> </em><em>so</em><em>,</em><em> </em><em>X </em><em>=</em><em> </em><em>1</em><em>6</em><em> </em><em>×</em><em> </em><em>3</em><em> </em><em>=</em><em> </em><em>4</em><em>8</em>
<em>X </em><em>=</em><em> </em><em>4</em><em>8</em><em>.</em>

Answer:
b = -1/10.
Step-by-step explanation:
(2i/2+i)-(3i/3+i)
= 2i(3 + i) - 3i(2 + i) / (2 + i)(3 + i)
= 6i + 2i^2 - 6i - 3i^2 / (2 + i)(3 + i)
= (-2 + 3) / (6 + 5i - 1)
= 1 / (5 + 5i)
Now we multiply top and bottom by 5 - 5i :
= 5 - 5i / (5 + 5i)(5 - 5i)
= 5 - 5i / 25 -25i^2
= 5 - 5i / 50
= 1/10 - 1/10i
The total amount he should pay is $69.6
20% of 58 is 11.6
11.6+58=69.6
The fraction of the remaining marbles in the bag will be blue is 6/17.
<h3>What fraction of the remaining marbles in the bag will be blue?</h3>
The first step is to determine the initial number of marbles in the bag:
Initial number of red marbles in the bag : (5/8) x 240 = 150
Initial number of blue marbles in the bag : (2/8) x 240 = 60
Initial number of green marbles in the bag : 240 - 150 - 60 = 30
Number of red marbles remaining after 1/3 is removed = (1 - 1/3) x 150
2/3 x 150 = 100
Number of green marbles remaining after 2/3 is removed = (1 - 2/3) x 30
1/3 x 30 = 10
Total number of marbles now in the bag : 100 + 10 + 60 = 170
Fraction of blue marbles = 60 / 170 = 6/17
