8 0

Answer:

x = 29 ,  b = -3

Step-by-step explanation:

<u>5 = b + 8</u>

5 - 8 = b

-3 = b

b = -3

<u>2x + 3b = 156</u>

156 / 3 = 52

52 / 2 = 26

x + b = 26

26 + 3 = 29

x = 29

6 3/5-2 4/5=?<br> Show how you got the answer
Viktor [21]

Hello there,

Okay so the question is asking us to subtract the two mixed numbers, 6 3/5 - 2 4/5, from each other...

The first step would be to change the mixed numbers to improper fractions:

  • 6 3/5 as improper fraction would be 33/5
  • 2 4/5 as improper fraction would be 14/5

Now we need to make sure that the denominators are the same and in this case they are.

Simply subtract 14 from 33 and you would get 19 and the denominator stays the same so you would get 19/5.

  • Now turn 19/5 into a mixed number and you would get 3 4/5

The answer to the 6 3/5 - 2 4/5 would be 3 4/5.

Hope I helped,

Amna
