The account decreased by
7,400×0.265=1,961
The account at the end of the year
7,400−1,961=5,439
Cos(60) = cos(90 - 30) = sin(30) = 1/2
This should be what you want.
<h2><u>EQUATION</u></h2><h3>Exercise</h3>
2(3 + 3y) + y = 11
First, apply the distributive property:
2(3 + 3y) + y = 11
6 + 6y + y = 11
6 + 7y = 11
Substract 6 from both sides:
6 - 6 + 7y = 11 - 6
7y = 5
Divide both sides by 7:


<h3><u>Answer</u>. The value of y = 5/7.</h3>
