Question

The sum of three and four tenths and a number is six and six tenths.

Answer 1

3.2 (and the equation is 3.4 + x = 6.6)

Explanation:

the word problem is written as:

3.4 + x = 6.6

we want to solve for x.

to isolate x by itself, subtract 3.4 from both sides. (3.4 - 3.4=0 & 6.6 - 3.4 = 3.2)

now we have x = 3.2

so x equals 3.2

hope this helps!! :)
