Can you simplify 4x - ( 2 - 3x ) + 5 ?
and simplify the ratio 0.6 : 2.4.
18b square to 45b
Thank you very much!!

4x - 2 + 3x + 5
7x = -3
x = -3/7
0.6 : 2.4 = 6 : 24 ( multiply both sides by 10)
= 1 : 4
18b^2 : 45b = 2b : 5 (the b's get cancelled out and 18/45 = 2/5)

this is just off the top of my head but
the function simplified is 4x+5 I think
=4x-(2-3x)+5
=-8x+12x+5
=4x+5
the ratio is 1:4
I`m not sure what you mean by 18b square to 45b I think you mean 18b^2 : 45b which would be 36b:5b or 6b^2 : 5b

4x - ( 2 - 3x ) + 5
=> 4x-2+3x+5
=> 7x + 3
You cannot solve for x because this is not an equation.

4x- (2-3x) + 5
4x -2 +3x +5
7x +3
.6 / 2.4 = 1/4
