Whats the answer to x^3 y^0 z^-2

Mathematics
1 answer:
Elina [12.6K]3 years ago
5 0

Answer:

\frac{x^3}{z^2}

Step-by-step explanation:

There are no given values, therefore we can't determine a definite answer. However, we are able to simplify the expression.

As we all know that any variable or number to the power of 0 is equal to 1. This means that y^0 = 1.

We also know that a negative power can bring the variable down and make it a fraction. This means that z^-^2=\frac{1}{z^2}

Now that we got these two sorted we are able to write it in a simplified form.

Answer: \frac{x^3}{z^2}

Jessi sold half her comic books. Then, she bought 9 more. She now has 11 total. How many did she begin with?
Alex Ar [27]

Answer:X+9=11

9-9|11-9

X=2

Step-by-step explanation:When the beginning number is unknown we use “x” to be a place holder. If she got 9 more books we would add 9 to the equation. Finally if 11 is the total, the end of the equation would equal 11.

lisabon 2012 [21]
Let
x-->volume of white vinegar you need to add to the mixture (measured in cups)
<span>then
the amount of the pure vinegar in the mixture will be -----> (10*0.1 + x) cups
t</span>he volume of liquid will be ---------> 10 + x
the concentration equation is-------> [(10*0.1 + x)/(10+x)]=0.50<span>multiply both sides by (10+x) and then simplify

</span>(10*0.1 + x)=(10+x)*0.50-----------> 1+x=5+0.50x-------> 0.50x=4
x=8

the answer is 
<span>you need to add 8 of a cup of the pure vinegar to the mixture</span>
