Solve the equation for<br> a. K = 4a+9ab
Elanso [62]
So try to isolate a by division and such
K=4a+9ab
we use reverse dstributive which is ab+ac=a(b+c) so
undistribute a
4a+9ab=a(4+9b)
k=a(4+9b)
divide both sides by (4+9b)
\frac{k}{4+9b}=a
a=\frac{k}{4+9b}

Answer:

0.375, Terminating

Step-by-step explanation:

Mackenzie has 32 books and 12 of which are by her favorite author.

One of the easier ways to convert something to a decimal is to first start as a fraction. We need to have it be the number of books by her favorite author (12) out of the total number of books that she owns (32)

This in the form of a fraction would be \frac{12}{32}

Now, let us reduce this fraction.

Both terms can be divided by 4

\frac{12}{32}/\frac{4}{4} \\\\\frac{3}{8}

Recall that \frac{1}{8} =0.125

This means that

\frac{3}{8} =3*0.125=0.375

As you can see. this decimal stops after 3 places, which means that it is terminating.

Step-by-step explanation:

let \: the \: let \: the \: length \: be \to \: x \\when \: folded :  it \: becomes \to \:  \frac{x}{2}  \\hence : \to \\  93.5 \times  \frac{x}{2}  = (93.5 - 1) \\ 93.5x = 2(93.5 - 1) \\ 93.5x = 2 \times 92.5 \\ 93.5x = 185 \\ x =  \frac{185}{93.5}  \\  \boxed{x = 1.9786096257 }\\
