Question

one morning the temperature was-5°F.by noon it had increased by 12 degrees. what was the temperature at noon? explain your answer.

Answer 1

$\huge{\boxed{7^{\circ}F}}$

Let's write this as an equation. $-5+12=x$

In this case, $x$ represents the temperature at noon.

To solve this, we simply need to add $-5+12$. We can also rearrange the terms to make a simpler equation. $12-5=x$

All we need to do is find $12-5$. $\boxed{7=x}$

Answer 2

Answer:

$7^{\circ}F$

Step-by-step explanation:

We are given that one morning the temperature was $5^{\circ}F$

By noon it had  increased by 12 degrees.

We have to find the temperature at noon and explain.

Temperature at morning=-5 degrees Fahrenheit

Temperature increased by =12 degrees

Therefore, the temperature at noon=12+(-5)=7 degrees Fahrenheit

Because temperature is increased by 12 degree therefore, 12 added to -5 degrees Fahrenheit to find the value of temperature at noon.

Sign of larger number is positive therefore, the sign of sum will be positive.

Hence, the temperature at noon=$7^{\circ}F$
