Answer:

the value of x would be 5.

F(x) is just showing that it is an equation, and therefore it means what number should be plugged in as in this specific problem would be represented by 5. Therefore if y=f(x) then y=5.

Amelie is shopping for children's books and puzzle books. She wants to purchase at least 2 more children's books than puzzle boo

X = 9
y = 6

Step by step:

Divide 15 by 2: 15 ÷ 2 = 7.5
Subtract 0.5 from 7.5 (this will later be added back): 7.5 - 0.5 = 7
Subtract 1 from 7 (she wants to buy at least 2 more children books): 7 - 1 = 6
Subtract 6 from 15 (6 being the number of puzzle books, 15 being the total number of items): 15 - 6 = 9 (number of children books)

The denominator of a fraction in simplest form is greater than the numerator by 3. If 7 is added to the numerator, and 5 added

jok3333 [9.3K]

So.. if we take the numerator to be say "a", then the denominator will be "a+3"

$\bf \cfrac{a}{a+3}\textit{ if we add }\frac{1}{2}\textit{ we get then }\cfrac{a+7}{a+3+5}
\\\\\\
thus\implies \cfrac{a}{a+3}+\cfrac{1}{2}=\cfrac{a+7}{a+8}\\\\
-----------------------------\\\\
\cfrac{a+3+2a}{2(a+3)}=\cfrac{a+7}{a+8}\implies \cfrac{3a+3}{2a+6}=\cfrac{a+7}{a+8}
\\\\\\
3a^2+24a+3a+24=2a^2+14a+6a+42
\\\\\\
a^2+7a-18=0\implies (a+9)(a-2)=0
\\\\\\
a=
\begin{cases}
2\implies &\frac{2}{5}\\\\
-9\implies &\frac{3}{2}
\end{cases}$

either of those two fractions will do
