Answer:
He bought 1 small bag and 6 large bags.
Step-by-step explanation:
We can set up 2 equations with the given information.
5x+8y=45
x+y=6
We can rearrange the second equation to solve for x.
x=6-y
Now we substitute x for 6-y in the first equation
5(6-y)+8y=45
30-5y+8y=45
30+3y=45
y+10=15
y=5
x=1
He bought 1 small bag and 6 large bags.

Step-by-step explanation:
The perimeter of a circle is the circumference of the circle. To find it, use the formula
.
The diameter here is two times the radius x, d = 2x. But here it has been decreased by 2 so it becomes d = 2x - 2.
Substitute into the formula.
