Answer:
x=3
Step-by-step explanation:
Make an equation
4(20)+10x+3=113
Multiply on the left side
80+10x+3=113
Combine like terms
83+10x=113
Subtract 83 on both sides
10x=30
Divide by 10 on both sides
x=3
So, she got 3 $10 bills back
Hope this helps! :)
Answer:
3 = x
Step-by-step explanation:
So all we really have to do is multiply ad then set the equation to equal x, here's how we do it!
We know that the total amount is 113, and four 20 dollar bills equals 80, while three 1 dollar bills equals 3!
The only amount we are missing is the 10 dollar bills! Which means the equation is this...
113 = 80 + 10x + 3
We can already simplify the left side to this...
113 = 83 + 10x
To solve for x, we have to isolate it by subtracting 83 from both sides of the equation, then it should look like this...
30 = 10x
Now we can divide by ten and that should give us the value of x!
3 = x
To check your answer, simply input 3 into the equation and see if it equals 113! It would be this...
113 = 83 + 10(3)
10 times 3 equals 30
30 plus 83 equals 113! It checks out! So olivia had 3 ten dollar bills!
