PLZ HELP ME! I WILL MAKE YOU BRAINLIEST! Xian and his cousin Kai both collect stamps. Xian has 60 stamps, and Kai has 76 stamps.

zvonat [6]

Answer: After 4 months they will have the same number of Stamps

Xian and Kai will have 124 stamps each one.

Step-by-step explanation:

60+16x = 76+12x (Subtract 12 from both sides)

-12 -12

60+4x = 76 (Subtract 60 from both sides)

-60 -60

4x/4x = 16/4x (Divide 16 by 4)

X = 4

Gnoma [55]

Answer:

$\frac{x^{2} + 19x - 56}{4 {x}^{2} - 32x}$

Step-by-step explanation:

Start by making the denominators of both fraction the same. This can be done by multiplying one fraction's denominator by the other.

After simplifying and combining the two fractions together, check if the numerator can be factorised such that there is a common factor in the denominator and numerator. In this case, the numerator cannot be factorised.

Lastly, expand the denominator.

$\frac{x + 7}{4x} + \frac{5}{x - 8}$

$= \frac{(x + 7)(x - 8)}{4x(x - 8)} + \frac{5(4x)}{4x(x - 8)}$

$= \frac{x(x) + x( - 8) + 7(x) + 7( - 8) + 20x}{4x(x - 8)}$

$= \frac{ {x}^{2} - 8x + 7x - 56 + 20x }{4x(x - 8)}$

$= \frac{ {x}^{2} + 19x - 56}{4x(x - 8)}$

$= \frac{ {x}^{2} + 19x - 56}{4 {x}^{2} - 32x}$
