Answer: x = 13.4
Step-by-step explanation:
We translate 'English' to 'math':
'decreased by' is subtraction
'is' means '='
12(x - 10) = 2x + 14
12x - 120 = 2x + 14
subtract 2x from each side
10x - 120 = 14
Add 120 to each side
10x = 134
Divide by 10 , to isolate the 'x'
x = 13.4
If we substitute 13.4 for 'x' back in the first equation, we get 40.8 for each side, so the equation balances.
I hope this helps.
1/4 = the probability of getting spiral wrapping paper
1/3 = the probability of getting a green ribbon
1/4 x 1/3 = 1/12 = the probability of getting spiral wrapping paper and a green ribbon
Just add the two numbers and divide them by two
