Answer:

Step-by-step explanation:

To be rational means to be able to express the result as the ratio of two whole numbers.

a) 4/7 + (-1/3) = 12/21 - 7/21 = 5/21 so rational

b) √(4) • 2/5 = ±2 • 2/5 = ±4/5 so both solutions are rational

$\frac{3}{5}$ - $\frac{3}{8}$ = $\frac{3 * 8}{5 * 8}$ - $\frac{3 * 5}{8 * 5}$ = $\frac{24}{40}$ - $\frac{15}{40}$ = $\frac{9}{40}$

Which of these is equivalent to the following expression? 5s - 11b + 3s - 12b A. -b + 8s -B.23b + 2sC. -23b + 8s D. b + 8s

Marina86 [1]

Answer:

Option b) and c) are correct

Step-by-step explanation:

Given expression is 5s - 11b + 3s - 12b

5s - 11b + 3s - 12b=8s-23b (Rearranging the right hand side terms)

5s - 11b + 3s - 12b =-23b+8s

Option c) is correct

By the definition of equivalent the given expression is the sum of the two terms ( the terms may vary or equal)

From the definition of equivalent we get, Option b) is also correct

Therefore Option b) and c) are correct
