The temperature on Monday is [tex]-4^{\circ} C[/tex]. On Tuesday, it is [tex]13^{\circ}[/tex] colder. What is the temperature on Tuesday?

A. [tex]-17^{\circ} C[/tex]
B. [tex]9^{\circ} C[/tex]
C. [tex]-9^{\circ} C[/tex]
D. [tex]17^{\circ} C[/tex]



Answer :

To determine the temperature on Tuesday, let's perform a step-by-step calculation:

1. The temperature on Monday is given as [tex]\(-4^{\circ} C\)[/tex].
2. The change in temperature from Monday to Tuesday is given as [tex]\(-13^{\circ} C\)[/tex]. This means that Tuesday is [tex]\(13^{\circ} C\)[/tex] colder than Monday.

To find the temperature on Tuesday, we start from the temperature on Monday and subtract the temperature change:

[tex]\[ \text{Temperature on Tuesday} = \text{Temperature on Monday} + \text{Temperature Change} \][/tex]

Substituting the given values:

[tex]\[ \text{Temperature on Tuesday} = (-4^{\circ} C) + (-13^{\circ} C) \][/tex]

Performing the addition of these two negative numbers:

[tex]\[ -4 + (-13) = -4 - 13 = -17 \][/tex]

Therefore, the temperature on Tuesday is:

[tex]\[ -17^{\circ} C \][/tex]

Hence, the correct answer is [tex]\(-17^{\circ} C\)[/tex].
