1) First, you would need to create an equation for this problem. Let x represent the unknown percentage.
\frac{35}{185} = \frac{x}{100}

Next, you would cross multiply. 
185x = 3,500

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 185. 
x = <span>18.918%

Your answer was correct!

2) </span>First, you would need to create an equation for this problem. Let x represent the unknown 85%. 
\frac{x}{190}<span> = </span>\frac{85}{100}<span>

</span>Next, you would cross multiply. 
100x = 16150<span>

</span>Now, all you would have to do is isolate the x. To do this, you would divide both sides by 100. 
x = 161.5

3) First, you would need to create an equation for this problem. Let x represent the unknown percentage.
\frac{24}{128} = \frac{x}{100}

Next, you would cross multiply. 
128x = 2,400

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 128. 
x = 18.75%


I hope this helps!

22  True  For all real Numbers A and B,  A  -   B   =    -B   +  A

23  True   For all real Numbers  P, Q, and R, P  -  Q  - R  =  P - R  - Q

24) True For all real Numbers  X, Y, Z and (X   +  Y )  +  Z  =  Z   +  (X  +  Y)

25) False  For all real Numbers M and N,  M/M * N = N/N ==> Example: 5/5  *  3  ≠   3/3  *  5

26) Examples:

Counterexamples =====>   5  - 0  = 5;   5/1   =  5  

5   -  3   ≠  3    -   5;   (5 -  3 )  -    2  ≠   5  -  (3   -  2 );    

6/3    ≠   3/6;   (24/6 )/2   ≠   24/ (6/ 2 )



Hope that helps!!!!                                         : )

What is f(3) for the quadratic function<br>f(x)=2x2 + x – 12?<br>F -3<br>G 3<br>H 6<br>I. 9​
PolarNik [594]

Answer:

f(3) = 9

Step-by-step explanation:

Wherever you see an x on the right, put a 3 in for that x

f(x) = 2x^2 + x - 12

f(3) = 2*(3)^2 + 3 - 12

f(3) = 2*9 + 3 - 12

f(3) = 18 + 3 - 12

f(3) = 9
