Question

If you add 0.43 to a certain number then subtract 0.58 from the result and then another 4.04, you’ll get 30.3. What is the certain number?
Please show how you did it.

Answer 1

Let's call the number x. Now, let's make an equation to help us solve this problem. 

(((0.43+x)-.58)-4.04) = 30.3
(0.43+x)-4.64 =  30.3
x-4.21 = 30.3 
x = 30.3 + 4.21
x = 34.51

The answer is 34.51 and there's the work for you. Have a great day!

Answer 2

Answer:

34.49

Step-by-step explanation:

You do it reverse

30.3+4.04=34.34

34.34+0.58=34.92

34.92-0.43=34.49
