Well you can start by figuring out what numbers add up to get 168
and you know that half of 168 would be 84.
 so that would mean that the two numbers are


and we know that there are 12 parts soo you can multiply 168 by 12 and you would get 14 for each part
then you multiply 14 by 7 and by 5

so the ratio would be 70 as 5::98 as 7

So we have ratio 5/7, and sum is 168, so clearly numbers are not 5 and 7 since 5 + 7 = 12, not 168, so ratio is 5x / 7x, where x is unknown number.

So now we can set up sum: 5x + 7x = 168

12x = 168

x = 168 / 12 = 14

So our two numbers are 5x and 7x, which are 5 * 14 = 70 and 7 * 14 = 98

So the answer is 70 and 98

Answer:

B

Step-by-step explanation:

The square of y would look like y^2 and decreased means subtraction

So the equation now y^2-

the quotient of 8 and y would be 8/y

The full equation is y^2-8/y

*here is step by step*
(Remember to add the 'x' to the slope)

-4x+6y=16

6y=4x+16

y= 4/6x + 2.66

The complete answer is:

Complete the statements.

Answer:

1. 30

2. 150

Step-by-step explanation:

3tan^2(x)-1 =0

Lets assume tan(x) = u

3u^2(x)-1 =0

Now we solve for 'u'

add 1 on both sides

3u^2(x) =1, divide both sides by 3

u^2 = \frac{1}{3}

Take square root on both sides

u = +-\frac{1}{\sqrt{3} }

We replace tan(x) for 'u'

tan(x) = +-\frac{1}{\sqrt{3} }  

x = 30 because tan(30) =+\frac{1}{\sqrt{3} }  in first quadrant

      x = 30      (tan is positive in first quadrant)

tan(x) =-\frac{1}{\sqrt{3} }                                                    

  x = 150 because tan(150) =-\frac{1}{\sqrt{3} }  in second quadrant

     tan is negative in second quadrant
