B. Kayla walks 23 4/5 miles in 7 days, the reason is because there are 7 days in a week and it says, "Kayla walks 3 2/5miles each day! (KEY WORK. EACH DAY) so since there is only 7 days in a week than the answer is B. If I am wrong please correct me. Hopefully this helps!
Answer:
$ 100
Step-by-step explanation:
Annual budget is $ 1200
Monthly budget would be $ 1200/12= $ 100
Step-by-step explanation:
b^2-4b+3=0
b²-3x-b+3=0
b(b-3)-1(b-3)=0
(b-3)(b-1)=0
either
b=3 or b=1
.
2n^2 + 7 = -4n + 5
2n²+4n+7-5=0
2n²+4n+2=0
2(n²+2n+1)=0
(n+1)²=0/2
:.n=-1
.
x - 3x^2 = 5+ 2x - x^2
0=5+ 2x - x^2-x +3x^2
0=5+x+2x²
2x²+x+5=0
comparing above equation with ax²+bx +c we get
a=2
b=1
c=5
x={-b±√(b²-4ac)}/2a ={-1±√(1²-4×2×5)}/2×1
={-1±√-39}/2
I think it would be $9.08 per pound
