Answer:
Step-by-step explanation:
The problem statement defines the variables and gives the relations ...
2b + f = 8 . . . . total cost on Monday
3b + f = 11 . . . . total cost on Tuesday
__
Subtracting the first equation from the second, we get ...
(3b +f) -(2b +f) = 11 -8
b = 3 . . . . . simplify
Substituting this into the first equation, we can solve for f
2·3 +f = 8
f = 2 . . . . . . . subtract 6
Bagels cost $3 per dozen; the delivery fee is $2.
Answer:
There are no gaps between the edges or vertices in a polyhedron. Examples of polyhedrons include a cube, prism, or pyramid. Non-polyhedrons are cones, spheres, and cylinders because they have sides that are not polygons.

Answer:
ummm where is the numbers....?
Step-by-step explanation:
D = 2m - 4 (Dad's age is 4 less than twice Mark's)
m + d = 95 (their ages total 95)
We have a value for d, so plug it in:
m + 2m - 4 = 95
Simplify:
3m - 4 = 95
Add 4 to both sides:
3m = 99
Divide by 3:
m = 33
