Answer:
The above has one solution
Hope this helps
Answer:
1. 4(.8)-3.5= 3.2-3.5= -0.3
2. 3(3)--5(5)-9(-1)= 9 - 25 + 9 = 18 - 25= -7
It depends on how big the backyard and the garden are
The general equation for this is d = s*t. d = distance flown, s = speed that the airplane travels, and t = time. So for this particular probelm you would use
d = 20*s
1. P = 2(9) + 2(4.5)
P = 18 + 9
P = 27 m
2. P = 5.2(2) + 1.3(2)
P = 10.4 + 2.6
P = 13 ft
3. P = 12.9(2) + 4.7(2)
P = 25.8 + 9.4
P = 35.2 cm
