Eddie is finding how many 1-cm cubes will fit into a rectangular prism
Zarrin [17]
I believe that the correct newer would actually be the last option. By this Eddie person finding the length of the cube, the small cube, as also the cube which is the bigger one, if we were just to find the length and just add them all up, we would then find how many would then fit.

A cab company charges $4 per cab ride, plus an additional $3 per mile driven. How long is a cab ride that costs $22?​
Doss [256]

Answer:

6 miles

Step-by-step explanation:

Flat fee is $4

Per mile is $3

Equation :

4 + 3m = 22

subtract 4 from both sides

3m = 18

divide each side by 3

m = 6

The ride is 6 miles.
