Answer:
x = 10
Step-by-step explanation:
2x/3 + 1 = 7x/15 + 3
<em><u>(times everything in the equation by 3 to get rid of the first fraction)</u></em>
2x + 3 = 21x/15 + 9
<em><u>(times everything in the equation by 15 to get rid of the second fraction)</u></em>
30x+ 45 = 21x + 135
<em><u>(subtract 21x from 30x; subtract 45 from 135)</u></em>
9x = 90
<em><u>(divide 90 by 9)</u></em>
x = 10
<h2>
Another solution:</h2>
2x/3 + 1 = 7x/15 + 3
<u><em>(find the LCM of 3 and 15 = 15)</em></u>
<u><em>(multiply everything in the equation by 15, then simplify)</em></u>
10x + 15 = 7x + 45
<u><em>(subtract 7x from 10x; subtract 15 from 45)</em></u>
3x = 30
<em><u>(divide 30 by 3)</u></em>
x = 10

These are the only ones i know. Sorry i cant be more helpful :(
Answer:
- 3 1/5
- 16 1/5
- 31 1/4
- 4/5
Step-by-step explanation:
An improper fraction is converted to a mixed number by doing integer division and expressing the remainder as a fraction with the divisor as the denominator.
... 19/5 = (3·5 +4)/5 = 3 4/5
The expressions involving exponents are evaluated to mixed numbers according to the Order of Operations. The exponent is evaluated before division, so ...
1. 4^2/5 = (4^2)/5 = 16/5 = 3 1/5
2. 3^4/5 = (3^4)/5 = 81/5 = 16 1/5
3. 5^3/4 = (5^3)/4 = 125/4 = 31 1/4
4. 4^1/5 = (4^1)/5 = 4/5
_____
If you intended fractional exponents, according to the Order of Operations, you need to put that fraction in parentheses. The denominator of the fraction is the root of the base number to the numerator power.
... 4^(2/5) = (4^2)^(1/5) = 16^(1/5) = ![\sqrt[5]{16}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B16%7D)
