At 7pm the outdoor temperature was -12degrees celsius. By 11pm the temperature in degrees celsius had dropped x degrees celsius. Which expression represents the temperature reading at 11pm.

a -12-x
b -12+x
c-12
d -12x
e 12
a is my answer

A total of m players came to soccer pratice the coach divides them into 6 groups of T players for drills but 3 players are left over. Which of the following equations expresses the relationship between the number of players out for soccer pratice and the number of players in each group.
a m=3T+6
b m=6T+3
c m=3(T+6)
d m=6(T+3)
e m=3(6T+1)
d

I agree about the thermometer.

6 groups of T plus three left over is b not d

To solve the first problem, you need to understand what the question is asking for. The question asks for the expression that represents the temperature reading at 11pm after a certain drop in temperature.

Given that the temperature at 7pm was -12 degrees Celsius, and it dropped by x degrees Celsius, you need to find the expression that represents the temperature at 11pm.

To do this, you can start with the initial temperature at 7pm (-12 degrees Celsius) and subtract the temperature drop (x degrees Celsius). The resulting expression would be -12 - x.

Therefore, the correct answer is option a) -12 - x.

Now let's move on to the second problem.

The question states that there are a total of m players who came to soccer practice. The coach divides them into 6 groups of T players for drills, but there are 3 players left over.

To express the relationship between the number of players out for soccer practice (m) and the number of players in each group (T), you need to find an equation that represents this relationship.

Since there are 6 groups, each containing T players, you can start with the equation 6T. However, there are 3 players left over, so you need to add 3 to this equation.

Therefore, the correct equation that expresses the relationship is: m = 6T + 3.

Hence, the correct answer is option b) m = 6T + 3.
