3+7+2+8+10 = 30
30 ÷ 5 = 6
Average = 6
2 and 7/10 + 5 and 3/10 = 8
7+3/2=5
It is: 8+7+7+5+3+2+2 = 34/7 => 4 and 6/7 which is the average mean
3/2 - 7/10 = 15/10 - 7/10 = 8/10 = 4/5
10
10 - 3 = 7 7 / 10 = .7 = 70%
7+3=10 10*2=20
3+7=10 10+2=12 12*2=24
35 units^2
7*7*2*2*5*3 =(7*7)*(2*3)*(2*5) =49*6*10 =(50-1)*6*10 =(50*6-6)*10 =(300-6)*10 =294*10 =2940
7 - 2 - 3 - 12 = 7 - 17 = -10
You have an operator missing between the 3 and 2. Putting the 4 standard operators in, these are the answers: 7 + 8 - 3 + 2 - 5 + 10 = 19 7 + 8 - 3 - 2 - 5 + 10 = 15 7 + 8 - 3 x 2 - 5 + 10 = 14 7 + 8 - 3 ÷ 2 - 5 + 10 = 18.5
