Matthew plays soccer for h hours per day for five days in a row. Over the weekend, he played in a soccer tournament for a total of 6.5 hours. Which expression represents the number of hours Matthew played soccer in a full week? 5 + h + 6.5
5h + 6.5
StartFraction h over 5 EndFraction + 6.5
11.5h

5h +6.5

Step-by-step explanation:

He plays h hours x 5 a week (5x---5h) then you have to add the 6.5 hours that he played on the other day of the week that then gives you the expression above

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

y=1/4x-4
