Tracey paid $195 for an item that was originally priced at $450. What percent of the original price did Tracey pay?

About 43%.

Step-by-step explanation:

Well... 195/450 = x/100

100 times 195 = 450x

19500 = 450x

19500/450 = 450x/450

= 43.3% ( the 3 after the decimal point is repeated, but I rounded to the nearest percent).

I hope this helps.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
