- 4x + 10 = 5x + 55

Move 5x to the other side

Sign changes from +5x to -5x

-4x-5x+10= 5x-5x+55

-4x-5x+10= 55

-9x+10= 55

Move 10 to the other side

Sign changes from +10 to -10

-9x+10-10= 55-10

-9x= 45

Divide both sides by -9

-9x/-9= 45/-9

x= -5

Answer: x= -5

Answer:

-5

Step-by-step explanation:

subtract 10 from both sides and subtract 5x from both sides and you’re left with -9x=45. divide both sides by -9 and you’re left with x=-5

Suppose the average yearly salary of an individual whose final degree is a​ master's is ​$43 thousand less than twice that of an
natka813 [3]

Answer:

A person who holds a master's degree would earn an average $63,000

A person who holds a bachelor's only would earn an average $53,000

Step-by-step explanation:

We will need to construct equations from the sentences.

Firstly, let the yearly average for a master's degree holder be m and that of bachelor's be b.

Now, we know that someone with a master's earn 43000 less than twice what someone with bachelors earn.

Mathematically,

m = 2b - 43,000

Combined, they have an average salary of 116,000

Mathematically,

m + b = 116,000

Now we have 2 equations to solve simultaneously.

m = 2b - 43,000 ......(i)

m + b = 116,000 .......(ii)

We can sub I into ii

2b - 43,000 + b = 116,000

2b+b = 116,000 + 43,000

3b = 159,000

b = 159,000/3 = 53,000

m = 2b - 43,000

m = 2(53,000) - 43,000 = 63,000

andreev551 [17]

two equations which can model this situation is :  y=2x  and  x+y=1250  

<u>Step-by-step explanation:</u>

Here we have , Bronson is an action and horror movie junkie. He started a movie review vlog and needs to keep up with his movie viewing at a high pace. It has been a total of 50 weeks since he has stated his vlog and he has watched 1250 movies. He has watched twice as many horror movies a action movies. We need to Write two equations that can model this situation.​ Let's find out:

Let Bronson watched x action movies and y horror movies , than according to question horror movies he watched is twice that of action movies i.e.

⇒ y=2x       ........(1)

Now ,  he has watched 1250 movies i.e.

⇒ x+y=1250            .......(2)

⇒ x+2x=1250

⇒ 3x=1250

Therefore , two equations which can model this situation is :  y=2x  and  x+y=1250  .
