2-(3x+5)=5-2x

i have too answers but need the right one lol​

Answers

Answer 1

Answer:

x = -8

Step-by-step explanation:

2 - (3x + 5) = 5 - 2x

Subtract 2 from each side.

-(3x + 5) = 3 - 2x

Apply the negative sign in front of the parentheses.

-3x - 5 = 3 - 2x

Add 5 to both sides.

-3x = 8 - 2x

Add 2x to both sides.

-x = 8

We can't have a negative x value, so we'll need to multiply each side by -1.

x = -8

Hopefully, this helped and wasn't too confusing!

Answer 2

Answer:

Solution given;

2-(3x+5)=5-2x

2-3x-5=5-2x

-3-5=3x-2x

x=-8 is your answer

Step-by-step explanation:

180 degrees = Triangle

Angle 1 = 60

angle 2 = 90 because it's a right triangle

A force of 50N is applied to the end of a lever to lift a rock that is 350N. What is the MA of the lever? Is it actual or ideal?

Answers

Answer:

MA = 7, Actual

Step-by-step explanation:

Input force = 50N

Output force = 350N

MA = Output force / Input force

MA = 350 / 50 = 7

The difference between an ideal MA and an actual MA is that the former (ideal MA) uses distance while the latter (actual MA) uses force.

This is an Actual Mechanical Advantage

The MA of the lever will be "7" and it is actual.

According to the question,

Input force,

50 N

Output force,

350 N

As we know the formula,

→ [tex]MA = \frac{Out\ force}{Inp \ force}[/tex]

By substituting the values, we get

          [tex]= \frac{350}{50}[/tex]

          [tex]= 7[/tex]

Thus the above answer is correct as well as it is actual.

A) [tex]-\frac{7}{4}[/tex]

Step-by-step explanation:

For this question, we can use the rise over run method, which means y over x.

So count how many it takes for the point on top to get to the bottom by x and y.

It takes 7 spaces down (y)  and 4 spaces to the right (x)

So do rise over run and we get

[tex]\frac{7}{4}[/tex]

Meaning that B and C are incorrect. Now what about A and D?

Well the slope is moving down, meaning that it is a negative slope, therefore there must be a negative sign for the slope.

[tex]-\frac{7}{4}[/tex]

A. is correct.
