Answer:
23 students letter d ran the 50 yard dash
18
Step-by-step explanation:
the time of the students:
23,24,24,28,32,32,34,35,37,37,38,41,43,56,55,55,56,61
there are 18 number so 18 students did it
11
The negatives cancel out so -66/-6 comes out to be 66/6 which equals 11.
So we have the equation:
First, let's subtract 9 from both sides:
Divide both sides by -4:
Add 1 to both sides:
Divide both sides by 2:
And we're done!
72
24 / 3 = 8
so
8*7 = 72
