Please help!
Paul [167]

Answer:

We can check this two ways: distributing the -0.5, and plugging in a number for x.

First, we can check this by distributing the -0.5.  Our equation becomes:

-1.5x -2.5 = -1.5x + 2.5

Clearly, this is not true.  We can show this one more time by plugging in a number for x.  I will use 2.

Now, we evaluate both sides and see if they are equal.

-3 - 2.5 = -3 + 2.5

-5.5 = 0.5

Clearly, this is not true.  These expressions are not equivalent.

Which expression represents the phrase "three times the sum of a number and 4"?
Andrej [43]

Let ANY VARIABLE = a number

You did not provide a list of expressions.

Let n = a number

The sum of a number and 4 = n + 4.

We now multiply 3 times n + 4.

Answer: 3(n + 4)

4/5 HELP! Find the missing side. Round to the nearest tenth
yawa3891 [41]

Answer:

x ≈ 18.9

Step-by-step explanation:

using the cosine ratio in the right triangle

cos19° = \frac{adjacent}{hypotenuse} = \frac{x}{20} ( multiply both sides by 20 )

20 × cos19° = x , then

x ≈ 18.9 ( to the nearest tenth )
