True. sin(x) is an odd function, so
and
You can solve this by cross multiplying and dividing. If you set 104/125 = x/100. 104 * 100= 10400 and you divide that by 125 and get 83.2, so the answer is 83.2% of the guests invited showed up.
Answer:
x=-1
Step-by-step explanation:
multiply both sides by 2
move the constant to the right
find the sum
then divide the 4 next to x
Dunno what the RACE method is, never heard of it before but.
3x is positive, has a variable.
-3 is negative, has no variable.
-3x^2 is negative, has a variable, and an exponent.
-5x is negaitive, has a variable.
Solve this ratio:
5 40
--- = -----
8 x
Then 5x = 320, and x = 64. So, on a day on which there are 40 lunch customers, there are 64 dinner customers (answer).
