20% of $175 is $35. Divided between 5 people (35/5=7) would be 7. So each person should tip $7.
The answer is 23 because you would substitute in the 4 for the X and multiply 5 times 4 = 20 then add 20 plus 3 and you get 23
Now it would be
-2.3+(-5.9)
now just add those two together
and u get -8.2
So the answer is A
These are not similar. For them to be similar, they need to exist in proportion to each other for every single side. The ratio of the 12:9 sides is 4:3 when reduced. The ratio of the other 2 sides is 5:3. They all have to have the same ratio for them to be similar.
well, a WHOLE is 1, in this case is 8/8, that'd be a whole.
so Billy does 1/8 in 15 minutes, well, there are 8/8, so do the whole recipe that'd be 8 * 15 minutes, or 120 minutes, or 2 hours.
or you can see it this way, 1/8 is 15 minutes, since there are eight 1/8's, then it'd take 15+15+15+15+15+15+15+15 minutes.
