Answer:

The number divided by was <span>32/45</span>

Explanation:

Let the unknown number be x

Then <span>3 <span>1/5</span>÷x=4 <span>1/2</span></span>

Write as

<span> <span>16/5</span>÷x=<span>9/2</span></span>

Suppose we had the common denominator of 10 then we would have:

<span> <span>32/10</span>÷x=<span>45/10</span></span>

Get rid of the 10: multiply through out by 10 giving:

<span> 32÷x=45</span>

<span>⇒<span>32x</span>=45</span>

<span>⇒x=<span>32/<span>45</span></span></span>

Let f(x) = .............
galben [10]

Answer:

4

Step-by-step explanation:

g(3) = -2(3)^2 -4 = 2(9) -4 = 18-4 = 14

|f(2)| = | 2^2 -3| = | 4-3| = 1

(g(3) +2) = (14+2) = 16

4*  |f(2)|  = 4*1 = 4
