First thing you must do is square root both sides. This gives you:
1/3y + 2 = √121 which becomes 1/3y + 2 = 11 and 1/3y + 2 = - 11
This is because both 11 and - 11 when squared are equal to 121. So we must solve for both to find the solutions.
1/3y + 2 = 11
Subtract 2 from both sides to get 1/3y = 9
Now multiply both sides by 3 to isolate the variable y
3(1/3y) = 9(3) which becomes y = 27.
Now for the other equation 1/3y + 2 = - 11
Again, subtract 2 from both sides to get 1/3y = - 13
And multiply by 3 to isolate the variable y
3(1/3y) = - 13(3) which becomes y = - 39
Your answer: y = - 39, 27
The third is the correct answer because when you reduced 25/65 you will get 5/13
Answer:
Subtract the 4 additional poems from what was published first:
22 - 4 = 18
Now 18 is 2/3 of what she wrote.
To find the total poems written divide 18 by 2/3:
18 / 2/3 = 27
Sh wrote 27 poems total.
Sin 3pi/4 is angle 135 degrees or 45 degrees below 180 degrees. Hence it's opposite side is 1 and adjacent is 1, implying the hypothenus is sqrt(2). Hence
Sin 3pi/4 = 1/sqrt(2). Now multiply by sqrt(2)/sqrt(2) to get:
[1/sqrt(2).] * [sqrt(2)/sqrt(2)] = sqrt2)/2
