X=29 and y=10
You would isolate one of the variables and then plug the expression into the other equation to find the value of one variable. Then you would plug this value into the other equation to determine the value of the remaining variable.
If you have a fraction, you can multiply any constant, if you do it on both the top and bottom and get the same answer. For example, multiply 2 on both sides of 1/3 to get 2/6, or 3 times 1/3 to get 3/9. So 2/6 or 3/9 would work.
Answer:
4 pizzas
Step-by-step explanation:
Equation:
12x + 7 = 55
12x = 55 - 7
12x = 48
x = 4
0.06 is the correct answer bud
Answer:
Rewriting the expression 
with a rational exponent as a radical expression we get ![\mathbf{\sqrt[9]{3} }](https://tex.z-dn.net/?f=%5Cmathbf%7B%5Csqrt%5B9%5D%7B3%7D%20%7D)
Step-by-step explanation:
We need to rewrite the expression with a rational exponent as a radical expression.
The expression given is:
First we will simply the expression using exponent rule 
As we know 2 and 18 are both divisible by 2, we can write
Now we know that ![a^\frac{1}{9}=\sqrt[9]{a}](https://tex.z-dn.net/?f=a%5E%5Cfrac%7B1%7D%7B9%7D%3D%5Csqrt%5B9%5D%7Ba%7D)
Using this we get
![=\sqrt[9]{3}](https://tex.z-dn.net/?f=%3D%5Csqrt%5B9%5D%7B3%7D)
So, rewriting the expression with a rational exponent as a radical expression we get
