Answer:
y and x = 1
Step-by-step explanation:
If the answer is 3, then you would have to multiply 2 by 1 to get 2 then add 1 to get 3, so its possible that y and x are both 1.
-2 = 3x/5 + 1
-2 - 1 = 3x/5
-3 = 3x/5
-3 * 5 = 3x
-15 = 3x
x = -15/3
x = -5
Answer:
<h2><em><u>399.20</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>,</u></em>
Original Price of a T.V. = 499
Percentage of decrease = 20%
<em><u>So</u></em><em><u>,</u></em>
Amount of price decreased is
= 20% of 499
- <em>[</em><em>On</em><em> </em><em>formulating</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>%</em><em> </em><em>into</em><em> </em><em>1</em><em>/</em><em>100</em><em>]</em>
- <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>
- <em>[</em><em>On</em><em> </em><em>further</em><em> </em><em>Simplification</em><em>]</em>
= 99.8
<em><u>Therefore</u></em><em><u>,</u></em><em><u> </u></em>
The new price after decreasing
= 499 - 99.8
= <em><u>399.20 (Ans)</u></em>
Well if I'm reading this right and it is 2 cups of sugar and 2 cups of flour then it would be an even mix 50 50
Given:
The geometric sequence is
To find:
The sum of first 8 terms of the given geometric sequence.
Solution:
We have,
Here, the first term is 4 and the common ratio is
The sum of first n terms of a geometric sequence is
Where, a is the first term and r is the common ratio.
Putting n=8, a=4 and r=-3, we get
Therefore, the sum of first 8 terms is -6560.
