To solve for y, you want to have all unknowns on one side and knowns on the other. to do this, we can divide both sides by 0.6 so that the knows are on the second side and y on the other. then, we can simplify to solve for y

The surface are would be 81 bc the base area is 9 and you have four triangles with the area of 18. Add them all up and you get 81
Answer: Yes
Step-by-step explanation:
A: 12 minutesAnswer to B: 36 minutesAnswer to C:
x = the length of one piece
y = the length of the other piece
the total length is 100 cm this means
x + y = 100
one piece is 16 inches longer than the other
first we need to convert inches to cm:
1 in = 2.54 cm
16 in = 2.54*16 = 40.64
now we can write
x = y + 40.64
by solving the system of equations
x + y = 100
x = y + 40.64
we find
x = 70.32 cm
y = 29.68 cm
the lengths of the two pieces are 70.32 cm and 29.68 cm.
