12=5x-13x-44
combine like terms
12 = -8x -44
add 44 to each side
12+44 = -8x
56= -8x
divide by -8 on each side
56/-8 = x
-7 =x
Answer:
No faster than 46 mph
Step-by-step explanation:
40*.15=6
6+40=46
(This is assuming they can go 15% over the speed limit and not that the car needs to be below 15% over the soeed limit)
There are 2000 pounds in a ton - so the rino weighs 3.75 x 2000 = 7500 pounds
a percentage can be converted to a decimal - if you want to know what 3.8% of a number is, move the decimal two spaces to the left 3.8% is 0.038 -
Multiply 7500 pounds by 0.038 - the answer is 285 pounds.
Answer:
0
Step-by-step explanation:
zero is not a natural number,it is a whole number
<h2>Answer</h2>
2
<h2>Explanation</h2>
First, we are going to use the law of fractional exponents: ![a^{\frac{1}{n} =\sqrt[n]{a}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7B1%7D%7Bn%7D%20%3D%5Csqrt%5Bn%5D%7Ba%7D)
We can infer form our expression that 
and 
, so let's replace the values:
![16^{\frac{1}{4} }=\sqrt[4]{16}](https://tex.z-dn.net/?f=16%5E%7B%5Cfrac%7B1%7D%7B4%7D%20%7D%3D%5Csqrt%5B4%5D%7B16%7D)
Notice that we can also decompose 16 into prime factors to get 
, so we can rewrite our expression as follows:
![\sqrt[4]{16}=\sqrt[4]{2^4}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B16%7D%3D%5Csqrt%5B4%5D%7B2%5E4%7D)
Finally, we can use the rule of radicals: ![\sqrt[n]{a^n} =a](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5En%7D%20%3Da)
, so:
![\sqrt[4]{2^4}=2](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B2%5E4%7D%3D2)
