75%=3/4
84/x=3/4
then you cross multiply
84*4=3x
26*4=x
104=x
<span>84 is 75% of 104</span>

Answer:
1.) (2,1) is a solution
2.) (4,3) is NOT a solution
Step-by-step explanation:
1.) (2,1)
These are these mean (x,y)
2=x and 1=y
You want to substitute the numbers for the letters in the equation.
so.
2(2)+1=5
4+1=5
5=5, This statement is true so (2,1) is a solution.
2.) Same as above. 4=x and 3=y
4(4)-3(3)=10
16-9=10
7 Does Not Equal 10, Therefore, (4,3) is Not a solution to the equation.
The answer is 54.27. Hope I was halpful
(1- cos2x) dx
= x - 1/2 sin2x + c
= x - 1/2 ( 2*sinx cosx) +c
= x - ((sinx) (cosx)) +c
