Answer:
n=3.4, n=1.3
Step-by-step explanation:
4n^2-19n+18=0
solve using quadratic formula
a=4, b=-19, c=18
n=-(-19)±√(-19)^2-4·4·18/2·4
(solve using calulator or PEMDAS)
(solve for both + and -)
n=3.4, n=1.3
Answer:
Your answer will be m= -6/5
Step-by-step explanation:
Answer:
k=135
Step-by-step explanation:
180=45+k
-45 -45
_________
135=k
435+25x=875-15x where x is number of weeks
435+40x=875
40x=440
x=11
Final answer: 11 weeks
