Answer 1

Respuesta:

A=5. B=4. C=-2. D=3. E=-1. F=8

a.3C+4D

$3( - 2) + 4(3) \\ = - 6 + 12 \\ = 6$

b.B+C+E

$4 - 2 - 1 \\ = 4 - 3 \\ = 1$

c.F+B-A+C

$8 + 4 - 5 + ( - 2) \\ = 8 + 4 - 5 - 2 \\ = 12 - 7 \\ = 5$

d.A+C+E-B

$5 + ( - 2) + ( - 1) + 4 \\ = - 10 - 1 + 4 \\ = - 11 + 4 \\ = - 7$

e.3A+5C

$3(5) + 5( - 2) \\ = 15 - 10 \\ = 5$

f.2F+3B-4D

$2(8) + 3(4) - 4(3) \\ = 16 + 12 - 12 \\ = 16$

g.2D+3B+2F-5E

$2(3) + 3(4) + 2(8) - 5( - 1) \\ = 6 + 12 + 16 + 5 \\ = 39$
