A moving company charges $40 plus point $.25 per mile to rent a van. Another company charges $25 plus point $.35 per mile to rent the same band. For what number of miles will the rental cost be the same for both companies?

150 miles

Step-by-step explanation:

m = mile

40 + 0.25m = 25 + 0.35m

0.25 * 150 = 37.5

37.5 + 40 = 77.5

0.35 * 150 = 52.5

52.5 + 25 = 77.5

77.5 = 77.5

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
