the difference between two numbers is 4. three times the smaller number minus four times the larger is -28.. what are the numbers?
x = 16 y = 12
9a squared - 121
x - first number, y - second number \[\begin{cases}x-y=4\\3y-4x=-28\end{cases}\] I hope you can do it yourself now x=16 y=12
The first number: x ==> smaller number The second number: x+4 ==> larger number =>3(x)-4(x+4)=-28 =>3x-4x-16=-28 =>3x-4x=16-28 =>-x=12 =>x=12 The number are: 12,16 :D
numbers*
i feel i had told u ld u the answer
12,16 are not possible answers and i typed the qestion exactly as it reads. answers are, 5,9 8,12 7,11 6,10
Not possible!
the problem you typed is definitely 12 and 16, maybe you typed it wrong?
nope, read it word for word
well, try plugging 12 and 16 into the problem you typed and you'll see they work correctly
where from u got this question
they do work
i think answers are wrong
Yes, maybe
