X + 0.30x = 143
1.30x = 143
x = 143 / 1.30
x = 110 <===

Answer:
54/40 = 1.35 or 135%
Step-by-step explanation:
10x^6y^3 + 20x^3y^2 / 5x^3y =
5x^3y (2x^3y^2 + 4y) / 5x^3y=
<span>2x^3y^2 + 4y
</span>
First you find what the expressions 10x^6y^3 and 20x^3y^2 have in common, and that is 5x^3y, which is the same as the denominator, so you can easily divide them and get 1.
