X= -5 because you divide -5x by -5 to get x alone so you have to 25/-5 which is -5
Answer:

Step-by-step explanation:
If the rectangle show one side of length 5 x +2, and another side of length x - 4, then the area of this rectangle (given by the product of the sides' length) is:

which is already written in standard form.

Answer:
7.7 ft
Step-by-step explanation:
The third longest side is also the second shortest side.
The 14 ft side of quadrilateral ABCD corresponds to the 6 ft side of quadrilateral EFGH.
14/6 = 18/x
7/3 = 18/x
7x = 18 * 3
7x = 54
x = 54/7
x = 7.7
Answer: D. 7.7 feet
Answer:
The correct option is 4.
Step-by-step explanation:
Given information:
Bring lunch : 46 males, 254 females
Buy lunch : 176 males, 264 females
Total number of peoples is

Total number of males is

The probability of male is

Since probability of males is 0.3, therefore options A and C are incorrect.
Total number of persons who buys lunch is

The probability of persons who buys lunch is

We need to find the probability of P(male | buys lunch).
According to the conditional probability, we get

P(male | buys lunch)
P(male | buys lunch)
P(male | buys lunch)
Therefore the correct option is 4.
