Solve for x. Please:)
lutik1710 [3]

Answer:

  x = 3

Step-by-step explanation:

The smaller triangle and larger one are similar, so corresponding sides are proportional.

  8/4 = (8 +(x -1))/5

  10 = x +7 . . . . . . . . . multiply by 5 and simplify

  3 = x . . . . . . . . . subtract 7

__

<em>Alternate solution</em>

The short segments are also proportional:

  (x -1)/(5 -4) = 8/4

  x -1 = 2 . . . . simplify

  x = 3 . . . . . . add 1

A bag of marbles contains 12 red marbles 8 blue marbles and 5 green marbles. If three marbles are pulled out find each of the pr
Jobisdone [24]

The probability of an event is calculated as = \frac{Favorable outcomes}{Total number of outcomes}

Here, the total number of outcomes = 12 red marbles + 8 blue marbles + 5 green marbles

So, total marbles = 25 marbles

Number of favorable or green marbles = 5 marbles

Probability of three green marbles if drawn with replacement = \frac{Number of favorable or green marbles}{Total number of marbles} ×\frac{Number of favorable or green marbles}{Total number of marbles} × \frac{Number of favorable or green marbles}{Total number of marbles}

Probability of three green marbles if drawn with replacement = \frac{5}{25} × \frac{5}{25} × \frac{5}{25}

Probability of three green marbles if drawn with replacement = \frac{1}{125}
