Answer: x=3.4

<u>Simplify both sides of the equation</u>

<u></u>10x+-4.5+3x=12x+-1.1<u></u>

<u></u>(10x+3x)+(-4.5)=12x-1.1(Combine Like Terms)

13x+-4.5=12x-1.1

<u>Subtract 12x from both sides</u>

<u></u>13x-4.5-12x=12x-1.1-12x\\x-4.5=-1.1<u></u>

<u></u>

<u>Add 4.5 to both sides</u>

<u></u>x-4.5+4.5=-1.1+4.5\\x=3.4<u></u>

Answer:

x = 3.4

Step-by-step explanation:

10x -4.5 + 3x = 12x - 1.1 \\ 10x + 3x - 12x = 4.5 - 1.1 \\ 13x - 12x = 4.5 - 1.1 \\ x = 3.4

Which variable expression represents the word phrase? five decreased by the sum of a number and three A. 5 – (m – 3) B. (m + 3)
Slav-nsk [51]
<h3>Answer:</h3>

C. 5 – (m + 3)

<h3>Explanation:</h3>

... Five decreased by ⇒ 5 - ___

... the sum of a number and three ⇒ (m+3)

So, the whole word phrase translates to ...

... 5 - (m+3) . . . . . matches selection C.

_____

"the sum of a number and 3" refers to the whole quantity (m+3), which is why we put it in parentheses. In English, the operative phrase is "five decreased by the sum", and the prepositional phrase "of a number and three" describes the content or nature of the sum.
