the answer is A


because if it was 64 at the end it had already increased by 8 and by 4 so to go before it increased just subtract the 8 and the 4

For this case, the first thing we must do is define a variable.

We have then:

x: temperature at the beginning of the day.

The algebraic expression that models the problem is given by:


x + 8 + 4 = 64

From here, we clear the value of x.

We have then:


x = 64-8-4

Therefore, the expression that models the temperature at the beginning of the day is:


64-8-4

Answer:


64-8-4

option A
