Answer:
0.58x3=1.74
Step-by-step explanation:
first, you line up the numbers, easiest with the 0.58 on top. then, you multiply 3x8, which is 24. you put the four in the hundredths place, and carry the two. then, you multiply 3x5 and get 15, and add the two, making it 17. you put the seven in the tenths place, and carry the one the ones place. then you will multiply three by zero and get zero. finally, you add the one, and your answer is 1.74.
Change in y = 6
change in x = -9
so slope is 6/-9 = 2/-3 =
ratio of 6:10, if you divide both numbers by 2 you get a ratio of 3:5
multiply by 2 you get 12:20
multiply by 1.5 you get 9:15
