Which value of d is a solution to equation 2.2d + 5.4= 12
ryzh [129]

Hello!

<em><u>Answer:</u></em>

<em><u>d=3</u></em>

<em><u>*The answer must have a positive sign.*</u></em>

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, you multiply by 10 from both sides of an equation.

2.2d*10+5.4*10=12*10

Then, you had to refine the problem down.

22d+54=120

Next, you subtract by 54 from both sides of an equation.

22d+54-54=120-54

Simplify.

22d=66

You can also divide by 22 from both sides of an equation.

\frac{22d}{22}=\frac{66}{22}

And finally, simplify and solve. You can also divide by the numbers.

66/22=3

Final answer: → d=3

Hope this helps!

Thanks!

-Charlie

Have a great day!

:)

:D
