Answer:

Step-by-step explanation:

First, find the midline by averaging the highest value (2) and the lowest value (-4). In other words, do (2+-4)/2. You get the midline as -1. Now find the distance from the midline to the top. Distance from -1 to 2 is 3. Amplitude is therefore 3.

Emily Elizabeth has $1.50 in dimes and nickels. She has 22 coins in all. How many nickels does she have?

Marat540 [252]

Answer:

$14$

Step-by-step explanation:

We can set up the following system of equations:

$\begin{cases}10d+5n=150\\d+n=22\\\end{cases}$ , where $d$ is the number of dimes she has and $n$ is the number of nickels she has.

Multiplying the second equation by -5 and adding both equations lets us isolate and solve for $d$ :

$10d+5n+(-5(d+n))=150+(-5(22)),\\5d=40,\\d=8$

Plugging $d=8$ into any of the two equations will let us solve for $n$ :

$8+n=22,\\n=\fbox{$14$}$ .

Therefore, she has 14 nickels.
