Answer:
15
Step-by-step explanation:
the common ratio is 1/2 so you do 30(1/2)
30(1/2)=15
4/5 is the sum of the answer. :)
Answer:
$384
Step-by-step explanation:
100%-25%=75% 100%-20%=80%
640*0.75=480 (price after 25% off)
480*0.80 =384 (price after the second discount of 20%)
Answer:
(0, 5) and (5,0) are two possibilities.
Step-by-step explanation:
There is an infinite number of ordered pairs that satisfy your inequality.
To help you pick some ordered pairs, you could plot the inequality (see the graph below).
Any point within the shaded area is a solution.
Pick an ordered pair, insert it into the equation, and check if the inequality is true.
Here are two examples.
<em>For (5, 0</em>):
0 – 3×5 < 10
0 - 15 < 10
-15 < 10 True
<em>For (0, 5)</em>:
5 – 3×0 < 10
5 – 0 < 10
5 < 10 <em>True
</em>
The ordered pairs (0, 5) and (5,0) are part of the solution set of the equation y – 3x < 10.
