<span>When the prices of two radios are increased by 20 we got the equation as 2x-5y=60.
When the prices are reduced by 5 we got another equation as x-5y=60.
By equating these two we will get zero for x and -twelve for y. the lowest terms of ratio is 0:-12.</span>
Answer:
9 weeks
Step-by-step explanation:
Knowing that the "q" is the total number of quizzes, you can set the equation equal to 12, and solve for w.
12 = w + 3 Subtract 3 both sides
9 = w
Y=-6/8X-3/8 is your answer
<u>We have to look for the pattern in the numbers</u>, so we can figure out what the next term in the sequence is !
It looks like,<u> each number is multiplied by 2!</u>
7 × 2 = <em>14 </em>
14 × 2 = <em>28 </em>
So, what's next?
28 × 2 = ?
The next term in the geometric sequence is ... 56!
I hope I helped :)
Comment if you have any confusion !
The answer would be 7
2(2)^2+3(2)-7=7
2(4)+3(2)-7=7
8+6-7=7
