Let
c-------> the number of cookies in each batch
we know that
To find the total number of cookies, multiply the number of batches by the number of cookies in each batch
so
------> equation that represent the total number of cookies
If Anna ate cookies
then

Answer:
d = m / v.
Step-by-step explanation:
The density is a measure of the specific weight of a substance or object.
This is, the mass per unit of volume. Then, the average density is the ratio of the mass of a body to the volume it occupies in space:
The equation for density is:
being m the total mass in the volume, and V the volume.
2x + a = b Subtract a from both sides
2x = b - a Divide both sides by 2
x =
