Ten times the square of a non-zero number is equal to sixty times the number.
what is the number ?

The number is 6

Step-by-step explanation:

This is a word problem and we must tackle it as such

Let's begin by translating it into mathematical expressions then solve the problem

Firstly

1.Let say the number is x

2.The square of the number is x²

3.Now 10 times the number is 10x²

4. 60 times the number is 60x

Now equating item 3 and 4 as stated by the problem is a gateway to our solution

Therefore

10x²=60x

Dividing both sides by x

We have

10x²/x=60x/x

10x=60

Dividing both sides by 10 we have

x=60/10

x=6

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
