Answer:

3.33 hours

Step-by-step explanation:

Take the total bill minus the flat charge. ($300 - $50 = $250)

Then take that amount and divide by the charge per hour.

($250/$75) = 3.33 hours

I need help with this question please.
Nikitich [7]
The answer would be yes. The way to solve this is by simplifying the first ratio. The first ratio should be girls to boys, which is 6:9. And since ratio can be fractions, 6:9 could be 6/9. Since 6/9 can simplify, you would get 2/3. Now we need to add the 2 girls and 3 boys back into the ratio. The ratio would then look like 8:12. And 8:12 could be 8/12, and 8/12 can be simplify, we get 2/3. So this means that the ratio stayed the same.

1/4m + 3/4m - 3/8(m+1)
sammy [17]
Distribute 3/8 to m and 1 so now the equation should be 1/4m + 3/4m - 3/8m + 3/8

then add 1/4m 3/4 to get m. the equation should now look like m - 3/8m + 3/8

m is 1m but the one is invisible so subtract 3/8 from 1 now the equation should look like 5/8m + 3/8

final answer: 5/8 + 3/8
