Hmmm.. I solved it and got 82%. I may be wrong, but try it out.

18.4%

Start by dividing 160 by 196 (which gives you 0.816... or 81.6%) which is the percent you're still paying, thus if you subtract that from 1, it should give you the percent off (1-0.816=0.186... or 100-81.6=18.4)

Write the inequality in slope-intercept form. 10x + 5y < 15

mestny [16]

Solve for y
minus 10x from both sides
5y<-10x+15
divide both sides by 5
y<-2x+3

Which graph shows the solution to this system of inequalities?<br> y>-1/3x+1<br> y>2x-3

Mademuasel [1]

Given:

The system of inequalities is:

$y>-\dfrac{1}{3}x+1$

$y>2x-3$

To find:

The graph of the given system of inequalities.

Solution:

We have,

$y>-\dfrac{1}{3}x+1$

$y>2x-3$

The related equations are:

$y=-\dfrac{1}{3}x+1$

$y=2x-3$

Table of values for the given equations is:

$x$ $y=-\dfrac{1}{3}x+1$ $y=2x-3$

0 1 -3

3 0 3

Plot (0,1) and (3,0) and connect them by a straight line to get the graph of $y=-\dfrac{1}{3}x+1$ .

Similarly, plot (0,-3) and (3,3) and connect them by a straight line to get the graph of $y=2x-3$ .

The signs of both inequalities are ">". So, the boundary line is a dotted line and the shaded region or each inequality lie above the boundary line.

Therefore, the graph of the given system of inequalities is shown below.

The circumference of the earth is 2.4x109 miles. if you traveled at an average of 8.5x10 miles per hour, how long would it take

pshichka [43]

Answer:

282 hr <======= see below

Step-by-step explanation:

Distance / rate = time

2.4 x 10^9 mi / 85 m/hr = 28235294 hr

You must have left the power of 10 off of your speed

probably should be 8.5 x 10^6 perhaps? then answer is 282

<h3>If speed was 8.5 x 10^5 then answer becomes ~ 2820 </h3>
