Answer:
woow there are so many numbers i dont understand no wonder why u need help
Substitute x with -12
1/3(9+(-12) = 1/3(-3)
the answer is -1
The constant is .o5 and that would be it all the time
Answer:
Let p be the number of phones sold and a be the number of accessory sold.
9p + 4a = 253
a - p = 8
Step-by-step explanation:
He gets $9 for every phone and $4 for every accessory, so you can write this as
9p + 4a
Then he made a total of $253 do the new equation is
9p + 4a = 253
We are also given that he sold 8 more accessories than phones. So we can write this as
a = p + 8
rearrange that so that all the variables are to one side.
a - p = 8
Now you have the two equations needed to solve the for the variable. The question didn't ask me to solve for the variable so I'll leave it here.
