Answer:
the answer is 36
Step-by-step explanation:
You would have to do this (1.25X3)+(0.45X2)=x then x=4.65, because 3X1.25=3.75 and 2X0.45=90 and 3.75+90=4.65
Answer:
5×2is your answer right answer
Simple, use the process of elimination to figure this out:
4x-y=2
2x+9y=-12
Convert these, to be able to find either x or y.
2(4x-y=2) 8x-2y=4 multiply by 2.
then
4(2x+9y=-12) 8x+36y=-48
Which makes them
8x-2y=4
-
8x+36y=-48
-38y=52
This simplified makes it y= -26/19.
Then plug y back into the original equation
4x-y=2
4x-(-26/19)=2
Making it x= 3/19.
Thus your Point of Intersection is at (3/19, -26/19)
