Answer:
11 cans cost $9.57
Step-by-step explanation:
There are two ways of doing this, one being the longer and the other being the shorter.
The shorter one is simply multiplying the number by the new number over 5:
This works because this finds the amount the 5 has increased from 5 to 11 and muliplies the number by this.
= 9.57
So 11 cans cost $9.57

Answer:
2 1/6 hours.
Step-by-step explanation:
It walks 1 1/2 miles in 3 1/4 hours.
So it walks 1 mile in (3 1/4 ) / (1 1/2) hours.
= 13/4 / 3/2
= 13/4 * 2/3
= 26/12 hours
= 2 1/6 hours.
A+b=15----(1)
a*b=54----(2)
(1) a=15-b ----(3)
put(3) in(2)
(15-b)*b=54
15b-b^2=54
b^2-15b+54=0
(b-9)(b-6)=0
so b=9 or b=6
if b=9 then a=15-9=6
if b=6 then a=15-6=9
answer two numbers are 6 and 9
