Answer:
Average weight
Step-by-step explanation:
Answer:
since the angle is up, x is the adjacent
cos= adjacent/hypotenuse
12 is the hypotenuse
cos35= x/12
cross and multiply:
x= 12*cos 35
I hope this will be helpful
X=invested at 10%12000-x=invested at 15% .10x+ (.15)(12000-x)=1440 ;; 12% of the total amount is 12% of $12000. .10x + 1800-.15x=1440
-0.05x=-360x=7200 12000-x=4800 $7200 at 10%=$720$4800 at 15%=$720 That is $12000 earning $1440, and that is 12%
It is a variable that represents a number
