Some examples of common types of sedimentary rock are sandstone, limestone, chalk, and clay. Sedimentary rock is important to the energy sector because this is the type of rock that forms fossil fuels.

sandstone, limestone, chalk, and clay.

Step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
