5.6 because 7=1=8 so 8-2.4=5.6
hope this helped please leave a thank you

Answer:
y^3/4x
Step-by-step explanation:
Given that the expression 6x^2/5y multiplied by some unknown gives answer as 3xy^2/10
We know that if ab = c, the b = c/a
Using the same principle, we have
unknown value = 3xy^2/10 divided by 6x^2/y
Use the fact that a/b divided by c/d = ad/bc
We get unknown = 5y(3xy^2)/6x^2 (10)
=15xy^3/60x^2
Simplify the constant part 15/60 as 1/4
xy^3 /x^2y
X term becomes x/x^2 = 1/x
so multiplying term =y^3/4x
General rule: The angles on a straight line total 180°
The right angle equates to 90°
Since that angle is half of our desired angle, it must mean that 2x + x = 90°
breaking this down, we get 3x = 90° which can be divided to make x = 30°
