Answer:
20 oz
Step-by-step explanation:
12 + 20 = 32
32 to 20 is equal to 8 to 5
For this case, the first thing we must do is define a variable.
We have then:
x: number of initial cards.
We write now the equation that represents the problem:
x - (4) * (6) = 54
From here, we clear the value of x:
x = (4) * (6) + 54
Rewriting:
x = 24 + 54
x = 78
Answer:

Step-by-step explanation:
25 x² - 10 x = 0
5 x ( 5 x - 2 ) = 0
x = 0 and
5 x - 2 = 0
5 x = 2
x = 2: 5
x = 2/5
Answer: B ) x = 0 and x = 2/5
