Step-by-step explanation:
x + y = 3 ---------------- eqn 1
y = -6x + 3 ------------- eqn 2
Substitute y for -6x + 3 in equation 1
x + -6x + 3 = 3
x - 6x + 3 = 3
-5x + 3 = 3
Collect like terms
-5x = 3 - 3
-5x = 0
Divide both sides by -5
x = 0

The answer is 2.5 percent
Answer:
x = -9
Step-by-step explanation:
1.4 - 0.2x = 3.2
0.2x = 3.2 - 1.4
0.2x= 1.8
x= -9
We can see that
There are four triangle on the surface
and five squares
For finding surface areas , we will find area of each surface and then add them
Calculation of area of triangle:
We are given
base=b=8
height=h=10
now, we can use area formula



Calculation of area of square:
base=width=8


There are four triangle and five squares on the surface
so, we can find surface area
SA=4* triangle + 5*square


so, surface area is
