Question

Г + г + г + г=200 а + а + а=15 в + в + в + в=60 г · а - в = ....

Answer 1

Ответ:

Пошаговое объяснение:

4г=200                     3а=15                     4в=60

г=200/4                    а=15/3                     в=60/4  

г=50                          а=5                         в=15

50*5-15=250-15=235

Answer 2

Let's start by solving the second equation, which tells us that "а + а + а = 15". We can simplify this by dividing both sides by 3 to get "а = 5".

Next, we can use the third equation, which tells us that "в + в + в + в = 60". Again, we can simplify this by dividing both sides by 4 to get "в = 15".

Now we can use the first equation, which is "Г + г + г + г = 200". We know that there are four "г" values, so we can simplify this to "Г + 4г = 200". We can rearrange this to get "Г = 200 - 4г".

Finally, we can use the fourth equation, which is "г · а - в = ...". We know that "а" is 5 and "в" is 15, so we can substitute those values in to get "г · 5 - 15 = 5г - 15". We can simplify this further by substituting "Г = 200 - 4г" in for "Г" to get "(200 - 4г) · 5 - 15 = 1000 - 20г - 15 = 985 - 20г".

Therefore, the value of "г · а - в" is equal to "985 - 20г".
