Answer:

1. 44 + 3x

2. 2y - 8

3. x - 6

15. $5\frac{7}{8}$

16. $6\frac{1}{3}$

17. $3\frac{7}{9}$

Step-by-step explanation:

1. 7² + 2² - 5 - 4 + 3x

49 + 4 - 5 - 4 + 3x

53 - 5 - 4 + 3x

48 - 4 + 3x

44 + 3x

2. - y - 5 + y + 2(2y-y) - 3

-y - 5 + y + 4y - 2y -3

-y - 5 + 5y - 2y - 3

4y - 2y - 5 - 3

2y - 8

3. 5x -3 - x - 3(x + 1²)

5x - 3 - x - 3x - 3

4x - 3x - 3 -3

x - 3 -3

x - 6

15. $7\frac{1}{4} - 1\frac{3}{8}$

= $7 \frac{2}{8} - 1\frac{3}{8}$

= $\frac{58}{8} - \frac{11}{8}$

= $\frac{47}{8}$ → $5\frac{7}{8}$

16. $9 - 2\frac{2}{3}$

= $\frac{54}{6} - 2\frac{4}{6}$

= $\frac{54}{6} - \frac{16}{6}$

= $\frac{38}{6}$ → $6\frac{2}{6}$ → $6\frac{1}{3}$

17. $10\frac{1}{3} - 6\frac{5}{9}$

= $10 \frac{3}{9} - 6\frac{5}{9}$

= $\frac{93}{9} - \frac{59}{9}$

= $\frac{34}{9}$ → $3\frac{7}{9}$

Hope this helps.
