Multiply the two mixed numbers 4 1/2 x 3 2/3 simplify your answer and write it as a mixed number
konstantin123 [22]

Answer: 16 1/2

Step-by-step explanation:

It's easiest to multiply improper fractions and then to convert them back into mixed numbers, so 4 1/2 would become 9/2 and 3 2/3 would become 11/3. \frac{9}{2} *\frac{11}{3}= 99/6. Now just simplify to 33/2 and then convert back into a mixed number.  16 1/2

Answer:

  • Option C

Step-by-step explanation:

Find the equation of the graphed line.

<u>Use 2 points, (0, -6) and (2, 4)</u>

  • m = (4 + 6)/2 = 5
  • b = -6

<u>The equation is:</u>

  • y = 5x - 6

<u>Compare with the given line y = 4x + 2</u>

  • 5 > 4 and -6 < 2

Correct answer choice is c

Figure out slope by using:
(y2-y1)/(x2-x1)

Plug in values:
29.98-15.49/50-25

Simplify:
14.49/25 = 0.5796

Then, use this ratio for the 40 lbs bag. So, then:
40*0.5796 = 23.184

So, your price for the 40 lbs bag should be $23.18 because cents only go up to 2 decimal places (otherwise, it would be $23.184).
