The answer is 308.6, assuming you mean round it to the tenths place of course. :) The first digit to the right of the decimal place in any number is the tenths place, but if the number directly to the right of that is above 5, you must round it up. In this case, because it is 308.61, you need to round it down to 308.6
Edited because for some reason I read it as 306.61 instead of 308.61.
Putting this into an equation, it would be (12 ÷ -3) + - (14 x 4)
-4 + -56 = -60
1/4th of Mai’s height is equal to 2/5th of Jon’s height
Let 'x' represent Mai's height and 'y' represent Jon's height.
Therefore, 1/4th of "x" should be equal to 2/5th of "y". This gives us the following equation :
(1/4)x = (2/5)y
multiply both sides by 4/y
x/y = 4*(2/5)
x/y = 8/5
x:y = 8:5
The ratio of Mai's s height to Jon's height is 8 to 5
We have 2( x^2 + 5x + 6) ÷ (x + 3) = 2(x^2 + 3x + 2x + 6) ÷ (x + 3) = 2[ x( x + 3) + 2( x + 3)] = 2( x+ 3 )( x + 2 ) ÷ ( x + 3 ) = 2( x + 2 ) = 2x + 4.
