X , y = 0
0 = 2x - 10
2x = 10
x = 5
Just divide both sides by 2 because you want to do the opposite operation, to isolate x so if you do you get 80 so x = 80
x is 6.
3 / 5 = 6 / 10
Where 10 / 5 = 2 then 2 * 3 = 6.
6 / 10 simplified by dividing both numerator and denominator by 2 will result to 3 / 5.
Answer:
The cost of a bag of chips is 
Step-by-step explanation:
Let
c ----> the cost of a bag of chips
we know that
The cost of a juice pouch ($2.50) plus the cost of 3 bags of chips must be equal to $5.05
The cost of 3 bags of chips is equal to multiply 3 by its cost c
so
The linear equation that represent this situation is

solve for c
Subtract 2.50 both sides


Divide by 3 both sides
