Answer:

Step-by-step explanation:
For this case we need to find the following integral:

And for this case we can use the substitution
from here we see that
, and if we solve for x we got
, so then we can rewrite the integral like this:

And if we distribute the exponents we have this:

Now we can do the integrals one by one:

And reordering the terms we have"

And rewriting in terms of x we got:

And that would be our final answer.
A) is right
b) just subtract ljm and kjm so 145-48 = 92°
c) 9x-25=7x+7 so here you put npq=mpq+mpn and you combine terms so it's now 2x=32 then divide by 2 on both sides and x= 16
now you just plug it into 3x-5 and you get 43°

just multiply lol
Answer:
50
Step-by-step explanation:
let x represent the total number of students.
8 / x = 16/ 100
16x = 800
x = 50
50 total students
4 times because if you count 10, 20, 30, 40, so it has to be 4
