Answer:
8/27 cups
Step-by-step explanation:
Nima uses 2/3 cups of peanuts to make a recipe of 2 1/4 = 9/4 cups of trail mix. If we want to find how many cups of peanuts are there per cup of trail mix, we can do a rule of three:
If 9/4 cups of trail mix need 2/3 cups of peanuts, 1 cup of trail mix need X cups of peanuts:
9/4 cups of trail mix -> 2/3 cups of peanuts
1 cup of trail mix -> X cups of peanuts
9/4 / 1 = 2/3 / X
9/4 = 2/(3*X)
3*X*9 = 4*2
27*X = 8
X = 8/27 cups
Primeiro multiplica o -2 com tudo que tem dentro do parenteses (chuveirinho) -114 = -5x -2(4x+18)
-2 . 4x = -8x + -2 . 18 = -36 = -8x-36
Agora soma os números com incógnitas (no caso x)
-114 = - 5x - 8x -36
Joga a incógnita do outro, tornando positiva
-114 = -13x - 36
13x -114 = -36
e o 114 do outro lado, ficando positiva também
13x -114 = -36
13x = - 36 + 114
13x = 78
x = 78 /13
x= 6
