One way is to divide the numerator by the denominator. For a mixed number make the fraction improper and do the same.
Answer:
x=4+y
Step-by-step explanation:
Answer:
The answer is (a + b )^2
Step-by-step explanation:
The answer is c. 46<span>
In a human diploid somatic cell (2n), there are 22 chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes - 22 pairs of autosomes and 1 pair of sex chromosomes. There are in total 46 chromosomes (23 pairs in 2 copies: 23 </span>× 2 = 46<span>).</span>
Answer:
![x = \frac{5a-2} {7+5a}\\](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B5a-2%7D%20%7B7%2B5a%7D%5C%5C)
Step-by-step explanation:
Given the expressions
![x = \frac{5}{9y+5}....1\\y = \frac{5}{5a-2} ...2](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B5%7D%7B9y%2B5%7D....1%5C%5Cy%20%3D%20%5Cfrac%7B5%7D%7B5a-2%7D%20%20...2)
Substitute 2 into 1
![x = \frac{5}{9(\frac{5}{5a-2} )+5} \\x = \frac{5}{(\frac{45}{5a-2} )+5} \\x = \frac{5}{\frac{45+5(5a-2)}{5a-2} } \\x= \frac{5}{\frac{35+25a}{5a-2} }\\x = \frac{5(5a-2)} {35+25a}\\x = \frac{5(5a-2)} {5(7+5a})\\\\x = \frac{5a-2} {7+5a}\\](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B5%7D%7B9%28%5Cfrac%7B5%7D%7B5a-2%7D%20%29%2B5%7D%20%5C%5Cx%20%3D%20%5Cfrac%7B5%7D%7B%28%5Cfrac%7B45%7D%7B5a-2%7D%20%29%2B5%7D%20%5C%5Cx%20%3D%20%5Cfrac%7B5%7D%7B%5Cfrac%7B45%2B5%285a-2%29%7D%7B5a-2%7D%20%7D%20%5C%5Cx%3D%20%20%5Cfrac%7B5%7D%7B%5Cfrac%7B35%2B25a%7D%7B5a-2%7D%20%7D%5C%5Cx%20%3D%20%5Cfrac%7B5%285a-2%29%7D%20%7B35%2B25a%7D%5C%5Cx%20%3D%20%5Cfrac%7B5%285a-2%29%7D%20%7B5%287%2B5a%7D%29%5C%5C%5C%5Cx%20%3D%20%5Cfrac%7B5a-2%7D%20%7B7%2B5a%7D%5C%5C)
