The midpoint between these two would be -7, as you would add these two numbers, and then divide by two.
50 =2×5×5
125=5×5×5
Hoghest common factor = 5×5
=25
Answer:
Cost of tshirt = £7.29
Cost of what = £0.86
Step-by-step explanation:
2t +3h = 12; 10t + 15h = 60
5t + 4h =33; 10t + 8h = 66
15h -8h = -6
7h = -6; h = -6/7; h = 0.86
2t +3(-6/7) =12
14t -18 = 84
14t = 102; t = 102/ 14; t=7.29
You can change 24.5% by moving the decimal point
24.5%=.245
70,000 x .245=$17,150
Let the weight of the first truck be represented by w.
total weight = w + (2 + w) + (2 + 2 + w) + (2 + 2 + 2 + w)
32 = 4w + 12
20 = 4w
w = 5
Therefore, the first truck weighs 5 tons, the second weighs 7 tons, the third weighs 9 tons and the fourth weighs 11 tons.
