<h2>34</h2>

Step-by-step explanation:

   The minimum charges for the phone service is $35. For, each text message, $0.50 is charged over and above the minimum charges.

   This problem can be modeled as a linear equation in the number of text messages sent as follows:\textrm{Total bill = Minimum charges + (Charge per message)x(Number of messages)}

\textrm{Total Bill = $}35\textrm{ + (Number of messages)x}($0.50)

   Given that the total bill is $52, number of text messages can be easily computed.

52\textrm{ = }35+\textrm{(Number of messages)x}0.50

\textrm{(Number of messages)x0.50 = }52-35=7

\textrm{Number of messages = }\frac{7}{0.5}=14

∴Number of text messages Juan sent = 14.

A bag contains 3 red. 3 white and 3 green balls. One ball is taken out of the bag
Xelga [282]

Answer:

The probability that the ball is red is 33.33%, it is not red 66.66%, and red or white is 66.66%.

Step-by-step explanation:

Given that a bag contains 3 red, 3 white and 3 green balls, to determine, if one ball is taken out of the bag at random, what is the probability that the ball drawn is (1) red, (2) not red, or (3) either red or white, the following calculations must be performed:

1)

3/9 = 0.333 x 100 = 33.33%

2)

6/9 = 0.666 x 100 = 66.66%

3)

6/9 = 0.666 x 100 = 66.66%

Therefore, the probability that the ball is red is 33.33%, it is not red 66.66%, and red or white is 66.66%.

smaller integer  added to three times the larger  <span>x + 3 ( x+2)
  </span>two less than five times the smaller  <span>5x - 2</span>

x + 3 ( x+2)   =  5x - 2

x+3x +6 = 5x -2 

x=8       
the first  integer = 8
