Its just a matter of subbing ur numbers into the formula given
1. d = rt
when r = 144 and t = 18
now we sub
d = 144 * 18
d = 2592 <==
2. d = rt
when r = 56 and t = 3.5
sub
d = 56 * 3.5
d = 196 <==
3. A = L * W
when L = 2 ft and W = 15 inches....this one u have to convert to inches...2 ft = 24 inches...so L = 24 and W = 15
A = 24 * 15
A = 360 in^2 <==
4. A = L * W
L = 3m and W = 32 cm...have to convert to cm.....1 m = 100 cm...so 3 m = 300 cm
A = 300 * 32
A = 9600 cm^2 <==
u basically do the same for all the others....its just a matter of subbing and solving
20 * (31/100) = 21*0.31=6.51
20.00-6.51=13.49
Caleb paid $13.49
Step 1. Divide by the numbers 0.25 (1 divided by 4):
0.25 x +2=5 divided by 8x-5
Step 2. Divide the by the numbers 0.625 (5 divided by 8):
0.25 x +2=0.625x-5
Answer: 0.25 + 2= 2.25
Please correct me if I'm wrong, hope I could help! :)
