3(x + 4) = x/2 - 8

First, we can multiply both sides by 2:

6(x+4) = x - 16

6x + 24 = x - 16

Isolate x:

5x = -16 - 24

5x = -30

x = -6

How many terms are in the expression shown below? 5x + 3y - 6

MA_775_DIABLO [31]

Answer:

Three terms.

Step-by-step explanation:

Hi there! I'm glad I was able to help you!

Our given expression: 5x + 3y - 6

The equation shown above has three terms. They aren't "like" terms, but altogether we still have three terms.

In mathematical wording, we would call this a TRI-nomial. The prefix "tri" obviously means "three", so this is an easy way to remember the answer!

Term 1: [ 5x ]

Term 2: [ 3y ]

Term 3: [ 6 ]

*** Putting the three terms together makes this a trinomial again! ***

I hope this helped you! You can leave a comment below if you have any other questions! :)

Can someone please help me with 7 and 8...thank you <3

Ivenika [448]

Answer:

Step-by-step explanation:

7. <A + [Since Co-interior angles]

=> 51° + <B = 180°

=> <B = 180° - 51°

=> 

8. <M + <N = 180°  [Since Co-interior angles]

=> 95° + <N = 180°

=> <N = 180° - 95°

=> <N = 85° (Ans)
