Subtract and reduce to lowest terms: 4 1/7 - 2 4/7

Mathematics
1 answer:
tatyana61 [14]3 years ago
5 0

Answer:

Step-by-step explanation:

Both terms have the same denominator, 7.  So combining them is relatively easy.  Rewrite 2 4/7 as 18/7 and then subtract 18/7 from 1/7:

1/7 - 18/7 = -17/7

Choose Answer 4:  None of these are correct.

Answer:

Denote the equation : y = ax + b

Use the first 2 values of x and y in table:

3a + b = 21

5a + b = 35

Subtract the 2 equations:

=> 2a = 14 => a = 7 => b = 21 - 3 x 7 = 0

=> The solution is  y = 7x

9.

Denote the equation : y = ax + b

Use the first 2 values of x and y in table:

5a + b = 17

10a + b = 22

Subtract the 2 equations:

=> 5a = 5 => a = 1 => b = 17 - 5 x 1 = 17 - 5 = 12

=> The solution is  y = x + 12

Hope this helps!
