Question

Given that is a = 3 , b = -4 and c = -2 evaluate 3a - b / 2c + 3a - c / c - b

Answer 1

Answer:

5.2

Step-by-step explanation:

= 3a - b / 2c + 3a - c / c - b

= 3(3) - (-4) / 2(-2) + 3(3) / -2 -(-4)

= 9 + 4 / -4 + 9 / -2+4

= 13 / 5 / 2

= 13 / 5 * 2

= 2.6 * 2

= 5.2

Answer 2

Answer:

Step-by-step explanation:

$\frac{3a -b}{2c}+\frac{3a-c}{c-b}=\frac{3*3-[-4]}{2*(-2)}+\frac{3*3-[-2]}{-2-[-4]}\\\\=\frac{9+4}{-4}+\frac{9+2}{-2+4}\\\\=\frac{13}{-4}+\frac{11}{2}\\\\=\frac{-13}{4}+\frac{11*2}{2*2}\\\\=\frac{-13}{4}+\frac{22}{4}\\\\=\frac{-13+22}{4}\\\\=\frac{9}{4}\\\\=2\frac{1}{4}$
