1. 9
2. 3 (This problem is explained on brainly here: brainly.com/question/485726)
3. Triangle because a lateral face is any face that is not a base.
4. 2:15. You first add three hours, then, 1/4 of an hour is 15 minutes. You multiply 15*3 because you're trying to find 3/4 of an hour. Then you have to add that to the current 30 minutes.
5. I can't see it, sorry. :(
6. 8. First, you have to find out how many inches are in 50 feet (50*12). Then, you divide that number by 75 to figure out how many rotations.

The probability of drawing two nickels from a bag at random without replacement is 33/95 . The probability of drawing a nickel f

Natasha_Volkova [10]

The probability that two events occur is equal to the product of the individual events happening or occurring. For this item, we let x be the probability that is unknown such that the relationship between them may be expressed as,
(3/5)(x) = 33/95
The value of x from the equation is 11/19.

A student solves the following equation for all possible values of x:

bekas [8.4K]

The correct answer is: 
C) his solution for x is correct, but in order for 6 to be an extraneous solution, one denominator has to result in 0 when 6 is substituted for x.

Explanation: 
To solve this rational equation, we cross multiply: 
8*(x-4)=2*(x+2).

Using the distributive property, we have 
8*x-8*4=2*x+2*2;
8x-32=2x+4.

Subtract 2x from each side: 
8x-32-2x=2x+4-2x;
6x-32=4.

Add 32 to each side: 
6x-32+32=4+32;
6x=36.

Divide both sides by 6:
 $\frac{6x}{6}$ = $\frac{36}{6}$ ;
x=6.

Extraneous solutions are solutions that come about in the problem but are not valid solutions to the problem; the only values of x that would give this sort of answer are -2 and 4, since these are the two values that would make one of the denominators 0 (we cannot divide by 0).
