So ram had 10 chocolates and i had 30 chocolates
because 1:3= 10:30
=> 4= 40
"Пятерку я получил не на третьем уроке" - ложь. Значит, пятерку Вася получил на третьем уроке.
"Четверку получил на втором" - тоже ложь. Значит, четверку Вася мог получить на перовом или на третьем уроке.
Выше мы выяснили, что на третьем уроке он получил пятерку, следовательно, четверку Вася получил на первом уроке.
Свободны остались только второй урок и тройка.
Ответ: Вася получил тройку на втором уроке.
Answer:
the answer is 2
Step-by-step explanation:
y=-6x+19
-6x+4y=16
-6x+4(-6x+19)=16
-6x-24x+76=16
-30x+76=16
-30x=16-76
-30x=-60
if there is - in both side we should cut them
30x=60
x=60/30
x=2

Answer:
f(x) = 8x + 2
Step-by-step explanation:
An easy way to test what the function is, is to fill in x wiht one of the imputs, lets try two of the options, 0 and then -4
If we fill in the x as 0 we have
8(0) +2 = 2 (Put it into the equation equal to the output) Now simplify
0+2=2 Anything times 0 is 0, now wehave
2 = 2 This proves that the equation is correct
If we tried it with -4 we would also see it is correct
8(-4) +2 = -30 First multiply the -4 and 8 because of PEMDAS
-32 + 2 = -30 Now simplify
-30 = -30 This proves that the equation works, if you had tried one of the other equations they wouldn't have been equal if you had only used the f(x) = 8x with the 0 it wouldn't have worked
8(0) = 2
0 ≠ 2
