The cost of one slice of mushroom pizza is $2.00 dollars. This is solved by subtracting the equations:  
X = cheese pizza 
Y = mushroom pizza  
(3X + 4Y = 12.50) 
- (3X + 2Y = 8.50)
 ______________ 
2Y = 4.00 
Y=2 or a slice of mushroom pizza is $2.00.

Simplify 64^-1/3<br> A. -4<br> B. -1/4<br> C. 1/4<br> D. 4
shepuryov [24]

Remember, the numerator of an exponenent represents the root. As well, a negative exponent means to take the reciprocal of the positive exponent (a^{-b} = \frac{1}{a^{b}}.

So, 64^{-1/3} is equal to \sqrt[3]{64^{-1}} which is 1/4, because 1/4*1/4*1/4 is 1/64 (1/64 cubed root is 1/4).

For example, a^{b/c} = \sqrt[c]{b^{b}}

The answer is c.

For what value of x is the rational expression below undefined?<br><br> 3x+15/6-x
Paha777 [63]

Let the function be (3x+15)/(6-x) then the value of x exists at -5.

<h3>What is the value of x?</h3>

Given: Rational Expression (3x+15)/(6-x)

To find the value of x when given a rational expression equivalent to 0.

To estimate the value of x, convey the variable to the left side and convey all the remaining values to the right side. Simplify the values to estimate the result.

Consider, (3x+15)/(6-x) = 0

3x + 15 = 0(6-x)

3x + 15 = 0

Subtract 15 from both sides of the equation, e get

3x + 15 - 15 = 0 - 15

simplifying the above equation, we get

3x = 0 - 15

3x = -15

Divide both sides by 3, then we get

x/3 = -15/3

x = -5

Therefore, the value of x exists at -5.

butalik [34]
The answer is D. because if there is 32 total, and 18 of them are girls, that means that there are 14 boys . with the question asking for girl/boy ratio it would have to be 18/14 in that order . if you divide 18 and 14 by two, they simple down to 9/7 . making the answer D.
