(3x-12)+12(xy-10), x=4, y=6
(3(4)-12)+12((4)(6)-10)
(12-12)+12(24-10)
0+12(14)
12*14=168

Answer:
C) 70
Step-by-step explanation:
Since they can only spend a maximum of $600, we can fill that in for c. Now, we can solve the equation for n.
600 = 8n + 40
~Subtract 40 to both sides
560 = 8n
~Divide 8 to both sides
70 = n
Best of Luck!
The vertical uprights on both sides of the number 8 mean to take the absolute value.
To get the absolute value of a number is really simple. If it negative, then make it positive by taking away the minus sign. If it positive, then do nothing.
Now we, -3 and 8 and of course the solution is '<' because -3 is less than 8.
Hope this helps!
