3n+4=-5
do the opposite of adding 4. this means you have to subtract 4 from 4. whatever you do to the problem, you must do to the answer. now subtract 4 from -5.
-5-4=-9
since 4-4=0, we can take 4 out of the equation. now you have:
3n=-9
now divide -9 by 3
-9/3=-3
n=-3
hope this helps :)
If you add all the gumballs together you get a total of 20200 gumballs now you just divide 5252 by the total number of 20200 to get the percent of 26% giving us the answer to what the percent of red there is in this container
(add all the number, divide the total number of reds by the total number of gumballs (5252 divided by 20200) which will give you the percent of red gumballs (26%)
Answer:
32
Step-by-step explanation:
40 = 100%
how many are 80% ?
well, 80% = 80× 1%
1% = 100% / 100
so, in our case
80% = 80×40/100 = 8×4 = 32
as a shortcut you consider a percentage x as a ratio factor of x/100 you multiply the 100% number with.
in our case
80% = 40 × 80/100 = 32
Answer:
420 students
Step-by-step explanation: I first did 300/5 which got me 60, meaning that one bus could transport 60 students. Then you do 60*7 (60 is how many students on each bus, and 7 is how many buses there are) and get 420 students on 7 buses.
