Correct! ^-^
s is equivalent s = 3 because 5 x 3 = 15 + 40 = 55
To solve the equation 5s + 40 = 55 using number sense, we want to isolate the variable s.
First, we can subtract 40 from both sides of the equation to get:
5s + 40 - 40 = 55 - 40
This simplifies to:
5s = 15
Next, we can divide both sides of the equation by 5 to solve for s:
5s / 5 = 15 / 5
This simplifies to:
s = 3
So the solution to the equation 5s + 40 = 55 using number sense is s = 3.
