x = 1
Answer:
there are 30 dolls in total
Step-by-step explanation:
Since 20% = 6 dolls ur gonna multiply that by 5 which gets 100% = 30
82 nickels he originally thought. 20 nickels per $1 so multiply 20 by 4 then add two nickels. Hope this helps.
X+y = 4, therefore y = 4-x when you rearrange the equation.
You can subsitute this in: x-(4-x) = 6
-4+x = 6-x
x=10-x
2x = 10
x = 5
Substitute x into the previous equation:
5+y = 4
y = 4-5
y = -1
