I need an answer to this big question
Kisachek [45]

Answer:

RS + ST = RT

23 - 2x     +     9x - 5     =     39

18 + 7x = 39

7x = 39 - 18 = 21

x= 21/7

x = 3

RS = 23 - 2x (given)

RS = 23 - 2(3)

     = 23 - 6

RS = 17

Consider the equation 5-3(2x - 7) = 12-5(x - 2). Is x = 2 a solution to this equation? Is x = 4 a solution to this equation? Exp
mario62 [17]

Answer:

x=4

Step-by-step explanation:

5-3(2x-7)=5-6x+21=-6x+26

--------------------------------------

12-5(x-2)=12-5x+10=-5x+22

--------------------------------------

-6x+26=-5x+22

-6x-(-5x)=22-26

-6x+5x=-4

-x=-4

x=4

May someone help me please. Solve for x and then find the indicated length. Pleaseee
Marina86 [1]

Answer:

16

Step-by-step explanation:

3x + 4 = x + 12  [The straight line on the segments AB and BC indicate that they are the same length]

2x = 8  [Subtract x and 8 from both sides]

x = 4  [Divide both sides by two]

Length AB is equal to (3x + 4) as indicated by the diagram. Substituting x = 4, (3 * 4) + 4 = 16

Simora [160]

Answer:

\frac{ \sqrt{7} }{2}

Step-by-step explanation:

The triangle is an isosceles triangle. Because the triangle is an isosceles triangle, the height and base of the triangle are equal to eachother.

a² + b² = c²

right now we have c² which is 7

a² + b² = 7

\frac{ \sqrt{7} }{2}

because a² and b² are = to eachother

now im lost dony listen to me lol.

You are considering buying a piece of industrial equipment to automate a part of your production process. This automation will s
Minchanka [31]

Answer:

No.

Step-by-step explanation:

The equipment wll save $35,000 per over for 10 years, which totals to $350,000.

If the equipment is bought on a simple interest rate of 12% annually for ten years, it will cost:

A = P (1 + rt),\\where\ A =\ Final\ amount,\ r=rate\of\interest\annually,\ t=time,\ P= Principal\ value\\\\P = 200,000r = 0.12t = 10 \\\\A = 200,000 ( 1 + 0.12\times 10)\\A = 200,000 (1 + 1.2)\\A = 200,000 (2.2)\\A = 440,000

We will need to pay $440,000 in total for the machine in over ten years.

If we compare both values, it can be deduced that industrial equipment is more expensive than labor cost.
