Manila decides to use some of her saving for a bike. She compared 3 brands RAZORZ swiftee and speedmonster the speedmonsters prics is 64.80 the razerZ is 20$ less than 2.5 x the price of the speedmonster the swiftee is 109 times the price of the razerZ what are the prices of swiftee and razerZ.

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

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

i think asking google will you get the answer to that question

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
