Answer:
I think the answer is 7.2
3 of 4 is not the correct way of writing a ratio.
X multiplied by 7+5=89
X x 7=89-5=84
X x7=84 divide both sides by 7
x=12
To solve this problem, we should set up an equation, letting x be the unknown number.
9 + x = 0
Next, we should subtract 9 from both sides to cancel out the +9 on the left side of the equation and get the variable alone.
x = -9.
Therefore, the number you are looking for is -9.
I would guess 2.8 to 3 feet wide :)
