If you want the answer simplified, its
-36x + 32
We know that
<span>sec a = 5/4
</span>sec(a)=1/cos(a)
then
cos (a)=1/sec(a)
cos (a)=1/(5/4)=4/5---> is positive because the function cos is positive in IV quadrant
the answer is cos(a)=4/5

Answer: It's 65.9
Step-by-step explanation:
<h3>decreased by 7.5%</h3>
<h3>means 100% - 7.5% = 92.5%</h3>
<h3>92.5% * x = 61</h3>
<h3>x= 61 / 92.5%</h3>
<h3>x = 65.9459</h3>
<h3>to the nearest tenth :</h3>
<h3>original number is 65.9</h3><h3>Hope this helps have a awesome day/night❤️✨</h3>
