Sierra is going shopping to buy art supplies. She plans to buy 2 paint brushes at p dollars each, 6 bottles of paint at b dollars each, and 3 canvases at c dollars each. Write two different algebraic expressions to represent the total cost in dollars of these items Sierra will buy.

b, i believe, but not sure.

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
