Answer:
95%
Step-by-step explanation:
To find the average, we add up all the scores and divide by 3.
We know 2 of the scores, but one is unknown, we will call it x.
Jenny wants the average to be 85, so we can set the expression equal to 85
=85
Multiply by 3 on both sides
160+x=255
Subtract 160 from both sides
x=95
She will have to score a 95 to pass the class with an 85 average
Hope this helps!
She would have to score a 75 or more
28.8
if you times 3.6 by 8 you get 28.8
Subtract 8 from both sides
-3x < 15 - 8
Simplify 15 - 8 to 7
-3x < 7
Divide both sides by -3
<u>= x > -7/3</u>
Hey there!
Good luck on your assignment and enjoy your day!

<u>Step-by-step explanation:</u>
cos x tan x - cos x = 0
cos x (tan x - 1) = 0
cos x = 0 tan x - 1 = 0
tan x = 1
