H = number of hamburgers sold.
c = number of cheeseburgers sold.
we know that "c" is three times the number of "h", thus c = 3h
we also know, the total amount sold for both is 556, h + c = 556
h + c = 556
c = 3h
thus
h + (3h) = 556 <---- solve for "h" to see how many hamburgers were sold.
what about "c"? well, c = 3h
C makes it true always true.
Step-by-step explanation:
3+3+3+3 is the answe because there are 4 rows of three
10×3×4
or 3×10×4
they will all equal the same thing. If that's what your asking?
