The temperature dropped 18 in 6 hours last night. The equation below can be used to find n, the average number of degrees the temperature changed each hour during that period.
-18/6=n
-3
-12
-24 THIS ONE
-108
2. In the following equations, a and b are equal. Which number could be substituted for both a and b to make both equations correct?
15*0 = -36 + a
24*8*0 = 36 - b
-36
51 This one I'm not sure
36
-51
1. -18/6= is not -24
2. No
okay, than is number one A?
Yes, A.
To find the average number of degrees the temperature changed each hour, we can use the formula:
Average change per hour = Total change / Total time
In this case, the total change is -18 degrees and the total time is 6 hours. Substituting these values into the formula, we get:
Average change per hour = -18 / 6 = -3
Therefore, the average number of degrees the temperature changed each hour is -3.
As for the second question, let's solve the equations:
15 * 0 = -36 + a
This equation simplifies to:
0 = -36 + a
a = 36
Now let's solve the second equation:
24 * 8 * 0 = 36 - b
This equation simplifies to:
0 = 36 - b
b = 36
Therefore, the number that could be substituted for both a and b to make both equations correct is 36.
