Let's simplify each expression step by step:<br /><br />1. $3(6-5x)+17x-10$<br /> $= 3 \cdot 6 - 3 \cdot 5x + 17x - 10$<br /> $= 18 - 15x + 17x - 10$<br /> $= 18 - 10 - 15x + 17x$<br /> $= 8 + 2x$<br /><br />2. $2(7.3-1.6a)+3.2a-9.6$<br /> $= 2 \cdot 7.3 - 2 \cdot 1.6a + 3.2a - 9.6$<br /> $= 14.6 - 3.2a + 3.2a - 9.6$<br /> $= 14.6 - 9.6$<br /> $= 5$<br /><br />3. $8(3y+4)-29y+14$<br /> $= 8 \cdot 3y + 8 \cdot 4 - 29y + 14$<br /> $= 24y + 32 - 29y + 14$<br /> $= 24y - 29y + 32 + 14$<br /> $= -5y + 46$<br /><br />4. $-5(0.3b+1.7)+12.5-8.5b$<br /> $= -5 \cdot 0.3b - 5 \cdot 1.7 + 12.5 - 8.5b$<br /> $= -1.5b - 8.5 + 12.5 - 8.5b$<br /> $= -1.5b - 8.5b + 12.5 - 8.5$<br /> $= -10b + 4$<br /><br />5. $7(2z-3)+6z-12$<br /> $= 7 \cdot 2z - 7 \cdot 3 + 6z - 12$<br /> $= 14z - 21 + 6z - 12$<br /> $= 14z + 6z - 21 - 12$<br /> $= 20z - 33$<br /><br />6. $-4(3.3-8c)+4.8c+5.2$<br /> $= -4 \cdot 3.3 + 4 \cdot 8c + 4.8c + 5.2$<br /> $= -13.2 + 32c + 4.8c + 5.2$<br /> $= -13.2 + 36.8c + 5.2$<br /> $= 36.8c - 8$<br /><br />So, the simplified expressions are:<br />1. $8 + 2x$<br />2. $5$<br />3. $-5y + 46$<br />4. $-10b + 4$<br />5. $20z - 33$<br />6. $36.8c - 8$
