One solution
11x + 25 = 7x+15
-7x -7x
4x+25=15
-25 -25
4x= -10

x= -10/4
-10/4 simplified is -5/2
so there is one solution where x=-5/2
Answer:
b(20) = 3 means that for 20 boxes of cards sold, 3 badges were earned.
Step-by-step explanation:
The number of badges earned based on the number of boxes of cards sold means that badges earned are a function of the number of boxes of cards sold.

Simplified would be
64t^10
The penny bank can hold 640 pennies
If you would like me to show how I got it I can
The difference between an algebraic expression and a numerical expression is that algebraic expressions contain numbers and variables. Numerical expressions only contain numbers.
Ex:
Algebraic Expression- 5x+9
Numerical Expression- 4+2
