B.) 9/55
this is because first you have a 2/11 chance of getting a girl's name then you have a 9/10 chance of getting a boys name.
Step-by-step explanation:
v=1/3nr2h for h
3(v)=3(1/3nr2h)
3v/2nrh=2nrh/2nr
3v/2nrh=h
h = 3v/2nrh
Answer:
there are 114
Step-by-step explanation:
Ratio of red marbles to black marbles is 19:1. (Data from 3rd sentence)
19+1= 20
20 units= 120 (Data from 1st sentence)
1 unit= 120/20= 6
19 units= 120-6= 114 (Values solved in working above)
Ans: There are 114 red marbles.
Answer:
the top right box
Step-by-step explanation:
Answer: Add 5 to both sides
What is the first step needed to solve 4 over 7 the whole multiplied by x minus 5 equal negative 13?
Answer- Add 5 to both sides
(4/7)x - 5 = -13
• As mentioned above, first step would be,
adding 5 to both sides
=> (4/7)x - 5 + 5 = -13 + 5
=> (4/7)x = -8
• Now, transporting 7 from L.H.S. to R.H.S
=> 4x = -8 × 7
=> 4x = -56
• Now in the same way, transporting 4 from L.H.S. to R.H.S
=> x = (-56/4)
=> x = -14
• And in this way, or taking<u> (Add 5 to both sides)</u> as our first step, we find that the value of x is -14.
<u>∴ </u><u> </u><u>x = -14</u>
Hope it helps.
