What is the constant? select all that are true. -8 -3.7 1/3 x 1 12

12,   -3.7,   1/3

Step-by-step explanation:

12+x-3.7 -8y +1/3

Combine like terms

12+x-3.7 -8y +1/3

12-3.7 +1/3   +x -8y

The first three terms are constants.  They never change value.  The terms with x and y are not constant.  They change as the variables change.

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

the rate of change is 25
