9n + 15 < = 10n + 24
9n - 10n < = 24 - 15
-n < = 9
n > = -9

Answer:
simplified 
Step-by-step explanation:
To turn a mixed number into a fraction :
3 x 4 =12 +2 =14 that will be your numerator (top number on a fraction)
and 4 will be your demoninator (bottom number)
We know that
length of a sector=[∅]*r--------> when ∅ is in radians
so
∅=length of a sector/r
for r=7 ft
length of a sector=4 ft
∅=4/7-----> 0.57 radians
the answer part 1) is 0.57 radians
part 2)
area of a sector=(∅/2)*r²--------> when ∅<span> is in radians
</span>area of a sector=(4/7/2)*7²-----> (4/14)*49----> 14 ft²
the answer Part 2) is 14 ft²
