Answer:
x = 15
Step-by-step explanation:
Assuming 3x and x-60 are in degrees, you can use:
cos(a) = sin(a+90)
To rewrite the equation as:
sin(3x) = sin(x-60+90)
sin(3x) = sin(x+30)
3x = x+30
2x = 30
x = 15
But, solving 3x = x+30 which simplifies to x=15 is not the only solution to this equation, as you can see in below picture. Finding all solutions is a bit more work, but maybe that is not required in your case.
Answer:
50 cents
Step-by-step explanation:
This is the equation I came up with: 150 = 100+<em>p</em>
Subtract 100 from 150 to leave the <em>p</em> alone.
50 = <em>p</em>
Answer:
Ok so QR=10 because x=5 and the bisector I believe is LM :)
Step-by-step explanation:
1)
evaluate when x = 6
5 + x
so when x = 6 then 5 + 6 = 11
answer
11
2)
2/6
in lowest term = 1/3 (divide top and bottom by 2)
3)
evaluate when x = 1
8 + x
so when x = 1 then 8 + 1 = 9
answer: 9
4)
14/48
lowest term = 7/24 (divide top and bottom by 2)
