Answer:
12, right?
Step-by-step explanation:
I think the declaration that three had spots may be a red herring meant to mislead you. If she has 7 after giving away 5, that would mean that in total, there are 12 cards.
For the first equation, to get an equation that only has 1 solution your two missing numbers could be 3x and 6. This is because when you solve it, you get 7x + 2 = 3x + 6
- 3x
4x + 2 = 6
- 2
4x = 4
x = 1
For the second equation, your two numbers could be 7x and 4, because it means that x has to be different as 7 multiplied by one number and added to 2 cannot equal 7 multiplied by the same number but added to 4.
I hope this helps!
Im sure others have questioned this so try doing that
Answer: 12+ 3n - 2 = 40
+2 +2
12 + 3n = 42
-12 -12
3n = 30
(Multiply)3 3
n=10
Step-by-step explanation:
The answer is 1/4 because 7/12 is larger than 1/2 but 1/4 is 2x smaller
