Question

Solve each equation.

A. 1/3a = -5 a =

B. 12 - b = 12.5 b =

C. -0.1 = -10c c =

Answer 1

`\\ \tt\hookrightarrow a/3=-5a`

`\\ \tt\hookrightarrow -a/3=5a`

`\\ \tt\hookrightarrow a=-a/15`

• So no solution except 0

#b

`\\ \tt\hookrightarrow 12-b=12.5b`

`\\ \tt\hookrightarrow 12.5b+b=12`

`\\ \tt\hookrightarrow (1+12.5)b=12`

`\\ \tt\hookrightarrow 13.5b=12`

`\\ \tt\hookrightarrow b=0.8888`

#c

`\\ \tt\hookrightarrow -0.1=-10c^2`

`\\ \tt\hookrightarrow c^2=0.01`

`\\ \tt\hookrightarrow c=0.1`

Answer 2

Answer: A.)0 B.)8/9 or 8.9 repeating C.) 1/100 or 0.01
