Answer:
9 socks for $8
3 socks at $15
Step-by-step explanation:
117 = (15 * x) + (8 * y)
8*9 = 72
15 * 3 = 45
72+ 45 = 117
9 socks at $8
3 socks at $15

Answer:
x = -6
Step-by-step explanation:
-1.5x = 9 Divide the -1.5 on both sides
x = -6
Plug in the answer to make sure it works.
-1.5(6) = 9
9 = 9
The question is an illustration of solving equations using estimates.
The student's strategy makes sense because he uses estimation to solve the given equation
The correct sequence of equation is as follows:
We have:

Add 0 to the equation

Express 0 as 1 - 1


Add another 0

Express 0 as 3 - 3


Rewrite as:

Solve
