12. Mr. Taylor, the curator of the children's museum, recently made two purchases of clay and wood for a visiting artist to sculpt. The first purchase was for 5 kg, of clay and 4 kg,
of wood and it cost $35,50. The second purchase was for 3.5 kg, of clay and 6 kg, of
wood and it cost $50.45, What was the cost of each product per kilogram?

hello 0xxbadwolfxx0,

2.6 x 10^9 is 2,600,000,000.

1.3 x 10^2 is 130

multiplying 130 and 2,600,000,000 would simply give you 200,000,000,000.

therefore, the answer would be d. 2.0 × 10^11.

i hope i ! warm regards, mae.

3xy cannot be combined with the others

2x, -5x and x are like terms

answer:

the answer is b) divide by -4 on each side and flip the sign.

step-by-step explanation:

we first need to start by dividing. this is because it is a multiplication problem to start.

we also need to make sure we flip the sign because any time you multiply or divide by negative numbers, the sign must be flipped.
