Question

Can someone please help me, I’m stuck

Answer 1

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

Answer 2

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
