Hello!
Answer:
d=3
*The answer must have a positive sign.*
Step-by-step explanation:
Distributive property: a(b+c)=ab+ac
First, you multiply by 10 from both sides of an equation.
[tex]2.2d*10+5.4*10=12*10[/tex]
Then, you had to refine the problem down.
[tex]22d+54=120[/tex]
Next, you subtract by 54 from both sides of an equation.
[tex]22d+54-54=120-54[/tex]
Simplify.
[tex]22d=66[/tex]
You can also divide by 22 from both sides of an equation.
[tex]\frac{22d}{22}=\frac{66}{22}[/tex]
And finally, simplify and solve. You can also divide by the numbers.
[tex]66/22=3[/tex]
Final answer: → [tex]d=3[/tex]
Hope this helps!
Thanks!
