Answer:
a) 1/27
b) 16
c) 1/8
Step-by-step explanation:
a) 
One of the properties of the exponents tells us that when we have a negative exponent we can express it in terms of its positive exponent by turning it into the denominator (and changing its sign), so we would have:

And now, solving for x = 9 we have:

b) 
This is already a positive rational exponent so we are just going to substitute the value of y = 8 into the expression

c) 
Using the same property we used in a) we have:

And now, solving for z = 16 we have:

Answer:
OD.0
Step-by-step explanation:
because 2(X+4)-1 = 2x+7
or, 2x+8-1 = 2x+7
or, 2x+7= 2x+7
and it cancels out eachother so it will be 0

Step-by-step explanation:
1 yard = 3 feet:
3.25 yards x 3 feet per yard = 9.75 feet.
1 foot = 12 inches:
9.75 feet x 12 inches per foot = 117 inches.
The volume of a rectangular prism can be given by the form

you know Volume, base, and height but you dont know width
so divide b and h to both sides

and you cna solve for width
now for 6.
dividing by a number is the same as multiplying by its reciprocal
