Answer:

Step-by-step explanation:

Use distribuitve property.

<u><em>DISTRIBUTIVE PROPERTY</em></u>

A(B+C)=AB+AC

A(B-C)=AB-AC

-3x-6x-8+5 ← (Group like terms & combine like terms.)

-3x-6x=-9x ← (Add and subtract elements to the numbers from left to right.)

-9x-8+5

-9x-8+5 ← (Solve & simplify)

-8+5 ← (Add & subtract.)

-8+5=-3

= -9x-3

$\Large\boxed{\mathsf{\Rightarrow -9x-3}}}$

Therefore, the correct answer is (C.) -9x-3.

Add the two expressions.<br><br> 2x + 6 and 6x −1<br><br> Enter your answer in the box.

MA_775_DIABLO [31]

Answer:

8x +5

Step-by-step explanation:

The sum is found by combining "like" terms—those that have the same arrangement of variables.

The first expression, 2x +6, has terms 2x and 6.

The second expression, 6x -1, has terms 6x and -1.

In each case, the first term listed is first-degree in the variable x. These are "like" terms, so can be added:

... 2x +6x = (2+6)x = 8x

The second term listed in each case is a constant. These are "like" terms, so can be added:

... 6 + (-1) = 5

Then the sum of the given expressions is the sum of the results from adding like terms:

... 8x + 5

Raymond just got done jumping at Super Bounce Trampoline Center. The total cost of his session was \$43.25$43.25dollar sign, 43,

rodikova [14]

Answer:

Raymond was for 29 minutes on the trampoline.

Step-by-step explanation:

We are given the following in the question:

Total cost of session = $43.25

Entrance fee = $7

Cost per minute = $1.25

Let t be the minutes that Raymond was on the trampoline.

Thus, we can write

Total cost =

Entrance fee + cost per mute(minutes that Raymond was on trampoline)

$C(t) = 7 + 1.25t$

Putting the values, we get,

$43.25 = 7 + 1.25(t)\\1.25t = 43.25 - 7\\1.25t = 36.25\\\\t = \dfrac{36.25}{1.25}\\\\t = 29$

Thus, Raymond was for 29 minutes on the trampoline.
