The difference in age between Brita and her daughter Eva is 30 years. The sum or their ages is 118. How old is Eva?

seraphim [82]

Answer: 44 years

Step-by-step explanation:

Let Brita's age be x and the daughter's age be y , then from the first statement :

$x - y = 30$

From the second statement :

$x + y = 118$

solving the resulting linear equation , add the two equations , we have

$2x = 148$

$x = 74$

substitute 74 into equation 1 to find the value of y

$74- y = 30$

$y = 74 - 30$

$y = 44$

Therefore :

Eva = 44 years

X2-7x-18÷x2+8x+12 what is it in lowest terms

Eddi Din [679]

$\dfrac{x^2-7x-18}{x^2+8x+12}=\dfrac{x^2+2x-9x-18}{x^2+6x+2x+12}=\dfrac{x(x+2)-9(x+2)}{x(x+6)+2(x+6)}\\\\=\dfrac{(x+2)(x-9)}{(x+6)(x+2)}=\dfrac{x-9}{x+6}$
