Step-by-step explanation:
The question needs to be more specific. But assuming it is 0.5y/(4/9), I will solve it.
This would make it 4.5y/4 =y + 3/8
- Multiply 4 to both sides
4.5y = 4y + 12/8
- Subtract 4y to both sides
0.5y = 12/8
- Divide both sides by 0.5
y = 3
Now plug in to check.
0.5(3)/(4/9)=3+3/8
Both equals 3.375!

Answer:
Therefore (x,y)=(3,7)
Step-by-step explanation:
put the second equation into the first
x+4=3x-2
x-3x=-2-4
-2x=-6
x=3
plug x=3 into the second equation
y=3+4=7
 
        
             
        
        
        
Answer:
<u>-289 degrees</u>
Step-by-step explanation:
You are looking for what is called  <u>Coterminal Angles</u>. 
To find a coterminal angle between 0 and 360 you <u>add or subtract</u> 360. 
- In this case, we subtracted 360 from 71
- 71 - 360 = -289 
- tan(-289) = 2.90
- If  TAN 71 = 2.90 and TAN -289 = 2.90, you know -289 is your answer.

To solve this, you need to subtract 180 from 400:  (400-180=220).  After that (I used the fraction/proportion/variable way, but there are others), so 220/400=%(p)/100.  Multiply diaganolly, so 400*p=400p, which is equal to 220*100=22000.  Therefore, 400p=22000.  Now, you have to isolate the variable by dividing both sides by 400: 400p/400=p, and 22000/400=55.  Therefore, p=55, or %=55, so the answer is 55%, or C.
