Question

2[-3(2*-1 + 3-8 + 42) - ½(20-10 - (-3))

Answer 1

Answer:

$-\frac{433}{2}$

Step-by-step explanation:

Change: 2[-3(2*-1 + 3-8 + 42) - ½(20-10 - (-3))

To: 2[-3(2*-1 + 3-8 + 42) - ½(20-10+3)

Multiplication calculation: 2 * (-3 x 35) $-\frac{1}{2}$ * 13

Multiply again: 2 * (-105) $-\frac{13}{2}$

Calculate: -210 $-\frac{13}{2}$

Answer: $-\frac{433}{2}$

I hope this help you! :D

Answer 2

Answer:

-238

Step-by-step explanation:

2(-3(2^-1+3-8+42)-1/2(20-10-(-3))=

2(-3(1/2+37)-1/2(10+3)=

2(-3(1/2+37)-1/2(13)=2(-3(75/2)-13/2)

=2(-225/2-13/2)

2(-238/2)= -238
