They are called invertebrats
Answer:
9.01
Step-by-step explanation:
10.00-15%+6%=9.01
No they are not equivalent.
When you multiply a number raised to an exponent to an identical number with an exponent you actually add the exponents together, not multiply them.
So x^3 * x^3 * x^3 would simplify to x^9
The second equation has a single value raised to exponents multiplied by each other so x^3*3*3 would simplify to x^27
X^9 is not the same as x^27
Because there is no equal sign, we can't know or find what x =. We can only simplify by adding like terms.
3x + 2x = 5x
-6 + 9 = 3
5x + 3 is the simplified answer.
Answer:
7%
Step-by-step explanation:
The additional tax is $0.42, we just have to find how much percent the tax ($0.42) is of the original cost ($6.00).
To do this, we can use the following formula:

Where x is the part (in this case, the tax ($0.42)), y is the whole (in this case, the original cost ($6.00)), and p being the percent (the tax rate in this case). We can replace the values in:

We can cross multiply and simplify to find the tax rate:

We're not done yet! We still need to turn it to percent. But we can do this by just multiplying our result by 100:

Place the percent sign and we are done.
Hope this helps.
