A. in order to keep the cards, the sum must be > 0. If the first card is negative the second card must be > the negative of of the same card.
example: 0.3 + -0.2 = 0.1
-0.2 is > -0.3

B. The card drawn is a -0.2. Same solution as (A) the second card must be > the negative of the card drawn. So she must draw > 0.2.
(0.5, 0.4, 0.3)

C. The card drawn is a -0.2. If the cards have to be put back due to negative sum, he drew a second card <0.2. This solution is the reverse of (B) except you discount 0.2 because this give a zero sum, not negative. (-0.5, -0.4, -0.3, -0.2, -0.1, 0.1).

<span>Calling the company that holds the car loan and asking them about other repayment options is the best tactic. This allows the loan holder to negotiate terms that would be acceptable to both sides, as well as showing that Angela is trying to make a good-faith effort to repay what she can. While it may increase the overall length of time that her payments require, it also shows that she is not going to outright default on the payments.</span>

Question 24 Multiple Choice Worth 1 points)

hammer [34]

Given:

The system of equations is:

Line A: $y=x-4$

Line B: $y=3x+4$

To find:

The solution of given system of equations.

Solution:

We have,

$y=x-4$ ...(i)

$y=3x+4$ ...(ii)

Equating (i) and (ii), we get

$x-4=3x+4$

$-4-4=3x-x$

$-8=2x$

Divide both sides by 2.

$-4=x$

Substituting $x=-4$ in (i), we get

$y=-4-4$

$y=-8$

The solution of system of equations is (-4,-8).

Now verify the solution by substituting $x=-4, y=-8$ in the given equations.

$-8=-4-4$

$-8=-8$

This statement is true.

Similarly,

$-8=3(-4)+4$

$-8=-12+4$

$-8=-8$

This statement is also true.

Therefore, (-4,-8) is a solution of the given system of equations, because the point satisfies both equations. Hence, the correct option is C.

A group of friends shared the cost of a printer. If John, Carl and Jason each paid $15, $25, and $112 respectively, then Carl pa

vfiekz [6]

The percent of the cost of the printer Carl paid is 16.45%

<h3>The total cost of printer</h3>

Since John, Carl and Jason each paid $15, $25, and $112 respectively, the total cost of the printer is T = $15 + $25 + $112 = $152

Since Carl paid $25, we need to find the percent of the total amount Carl paid.

<h3>Percent Carl paid</h3>

So, percent Carl paid = amount Carl paid/total cost × 100 %

Since amount Carl paid = $25 and total cost = $152,

Substituting the values of the variables into the equation, we have

percent Carl paid = amount Carl paid/total cost × 100 %

percent Carl paid = $25/$152 × 100 %

percent Carl paid = 0.1645 × 100 %

percent Carl paid = 16.45%

The percent of the cost of the printer Carl paid is 16.45%
