See the plants grow in airthemetic progression.
day 1 its is 1 and day 2 it is 2, day 3 it is 4.......
so,
1,2,4,6,8,......
so it take 48 days to fill the pond..
total plants = 48/2(2*1+(48-1)*2)
total plants= 2304
so half the plants is 1152
so,
1152=n/2(2*1+(n-1)2)
n=47
it so 47 days to complete half the pond.

1/3x-137.45=252.60 what is the value of x
nikdorinn [45]
The value of x is 1170.15 because first you add 137.45 from both sides of the equation, then your new equation should be 1/3x=390.05. After that you use the keep change flip method to help you divide 390.05 by 1/3 which will be 390.05 times 3 divided by 1 and your final answer should be x=1170.15 or 1170.15

Solve the inequality for u.<br> 22≤-4u-2<br> Simplify your answer as much as possible.
larisa [96]

Answer:

<u>u ≤ -6</u>

Step-by-step explanation:

Given :

  • 22 ≤ -4u - 2

Add 2 on both sides :

  • 22 + 2 ≤ -4u - 2  + 2
  • -4u ≥ 24

Divide both sides by -4 (remember the sign changes direction when divided by a negative number) :

  • -4u/-4 ≥ 24/-4
  • <u>u ≤ -6</u>
