Question

The sum of 7 2/10 and the number is 10 first write an equation to describe the situation

Answer 1

Lets call our name X, so by the question we can find the expression:

`x+7.2=10`

We can add -7.2 to both sides of the equation to find our number:

`x+7.2-7.2=10-7.2\rightarrow x=2.8`

So our number is 2.8
