Answer:
x = ?
Step-by-step explanation:
Equation written the right way:
d x (3 + x) = kx + 9d (-3 + x) = kx + 9d (-3 + x) = kx + 9
There is no steps or further way to find what x equals.
But above is the right way you should have typed it out and if anyone had figured out the answer, please put it in the comments.
Answer:
the answer is y= 5
Step-by-step explanation:
15,60, and 45 are all multiples of 5
Answer:
Step-by-step explanation:
Answer: x=3 and y=5
Step-by-step explanation: 11x-6y=3, 5x-8y=-25
11x-6y+6y=3+6y
11x/11=3/11+6y/11
x=3+6y/11
5(3+6y/11)-8y(11)/11
5(6y+3)-88y/11
30y+15-88y/11
88y-30y
58y
11(15-58y)/11=11(-25)
15-58y-15=-275-15
-58y/-58=-290/-58
y=5
x=3+6(5)/11
3+30
33
33/11
x=3
x=3, y=5
<em><u>Question:</u></em>
The sum of first n terms of an AP is given by Sn= 2n square +3n. Find the sixteenth term of the AP
<em><u>Answer:</u></em>
16th term of AP is 65
<em><u>Solution:</u></em>
Given that,
<em><u>The sum of first n terms of AP is given by:</u></em>
Let nth term in AP be:
<em><u>Then the nth term is given as:</u></em>
Where, from given,
<em><u>Thus nth term is given as:</u></em>
<em><u>To find the 16th term, substitute n = 16</u></em>
Thus 16th term of AP is 65
