Step-by-step explanation:

$x-(-y)=x+y\\\\\text{substitute}\ x=-2.31,\ y=5.9:\\\\-2.31+5.9=5.9+(-2.31)=5.9-2.31=5.90-2.31=3.59$

4. Jim and Kirk are playing a card game where they trade chips. At the beginning of the game, Jim has four times as many chips a

s2008m [1.1K]

Answer:

(a) $j = 4k$

(b) $4k - 18 = 18 + k$

(c) Jim initially had 48; Kirk initially had 12

Step-by-step explanation:

Given

$j = Jim$

$k=Krik$

Solving (a): An equation for the amount they originally had.

From the question, we understand that j is 4 times as many as k.

Mathematically, this is:

$j = 4 * k$

$j = 4k$

Solving (b): Equation after Kirk wins

Initially Kirk had k.

To get the new expression, we add 18 to k.

This gives: 18 + k

In the same vein, Jim's number of chirps will reduce by 18.

Initially, Jim had j chirps (or 4k chirps)

To get the new expression, we subtract 18 from j.

This gives: j - 18

So, the equation is:

$j - 18 = 18 +k$

Solving (c): Number of chirps they started with.

In (b), we have:

$j - 18 = 18 +k$

Substitute 4k for j

$4k - 18 = 18 + k$

Collect Like Terms

$4k - k = 18 + 18$

$3k = 36$

Divide both sides by 3

$k =12$

Substitute 12 for k in $j = 4k$

$j = 4 * 12$

$j = 48$
