Answer:
There area 14 one cent stamps
Step-by-step explanation:
Let
x -----> the number of 1 cent stamps
y -----> the number of 8 cent stamps
z -----> the number of 12 cent stamps
we know that
0.01x+0.08y+0.12z=1.78 -------> equation A
x=y+4 ------> y=x-4 -----> equation B
x=2z -----> z=0.5x ------> equation C
substitute equation B and equation C in equation A and solve for x
0.01x+0.08(x-4)+0.12(0.5x)=1.78
0.01x+0.08x-0.32+0.06x=1.78
0.15x=1.78 +0.32
0.15x=2.10
x=14
therefore
There area 14 one cent stamps
Answer:
196 
Step-by-step explanation:
Surface are of 2 rectangles = 2(2*4) = 16 
surface are of the base rectangle = 4*3 = 12 
Area of tow triangles =2(
* 2* 2)= 4
total = 16+12+4
= 196 
The answer for x is x=6 sorry if I’m wrong
