Answer:
x=12
Step-by-step explanation:
5x+4+64+52=180
We move all terms to the left:
5x+4+64+52-(180)=0
We add all the numbers together, and all the variables
5x-60=0
We move all terms containing x to the left, all other terms to the right
5x=60
x=60/5
x=12
Hey there! I'm happy to help!
This number is sixty six thousand six hundred eighty one. This means that our ten thousandths place is the first 6.
We look to the right place to see if it is 5 or bigger. It is also six.
Therefore we bump the ten thousands place up 1 to 7 and we make everything else 0, giving us 70,000.
Have a wonderful day! :D
