Step-by-step explanation:
The bike cost $199 to get $199 you do a number line then label 520 then at the end label 321 so then you do -20 then -100 then -50 then -20 then -9. so now you add them up 20+100+50+20+9 which equals =199
so bike cost $199
then 520%×199= 1034.8
or 520%×321=1669.2
so the percentage is 1669.2 or 1034.8 probably 1669.2 but they bot count.
I think it’s 3 times because 2*3=6 and 4*3=12 and 6*3=18
Sec^-1 OR arcsec .........
4n - 7 = 29
That's the equation :)
You can use any variable; doesn't have to be n.
If you want to solve for the variable, then it would be 5.5
38 degrees.
EXPLANATION
There are 2 angles.
The angles must add up to 180.
So taking 180 and subtracting the already known angle, of 142.
Will get us with 38.
We can check the work by doing 38 + 142.
Hope this helps! have a gud day
