Hi there & welcome to brainly !
Answer:
[tex] \huge{ \bold{ \boxed{ \tt{1.4}}}}[/tex]
Step-by-step explanation:
[tex] \text{Given : f \: = \: 12 \: g = 2}[/tex]
[tex] \text{To \: find : Value \: of \: given \: expression}[/tex]
[tex] \text{Let's \: start}[/tex] :
[tex] \text{0.5f \: - 2.3g}[/tex]
Here, The values of f and g are 12 and 2 respectively. Plug the given values :
↦ [tex] \text{0.5 ∗ \: 12 - 2.3 ∗ 2}[/tex]
Multiply : 0.5 and 12
↦ [tex] \text{6 - 2.3 \: ∗ \: 2}[/tex]
Multiply : 2.3 and 2
↦ [tex] \text{6 - 4.6}[/tex]
Subtract 4.6 from 6
↦ [tex] \text{ \boxed{1.4}}[/tex]
Hope I helped!
