The temperature at a mountain base camp was −3 degrees celsius on monday. tuesday morning, the temperature was 2 degrees celsius lower than it was on monday. by tuesday evening, the temperature was 4 degrees celsius lower than it was that morning. what was the temperature at the base camp tuesday evening?

The temperature was -9°C on Tuesday evening.

Step-by-step explanation:

Given,

The temperature on monday = -3°C,

Also, on tuesday morning, the temperature was 2 degrees Celsius lower than it was on Monday,

So, the temperature on tuesday morning = -3°C - 2°C = -5°C,

And, on tuesday evening, the temperature was 4 degrees Celsius lower than it was that morning,

Hence, the temperature on tuesday evening = -5°C - 4°C = -9°C

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
