Three red rods are 2cm longer than two blue rods. Three blue rods are 2cm longer than four red rods. How long is each rod?
nydimaria [60]

Answer:

The length of each red rod is 10 cm and the length of each blue rod is 14 cm

Step-by-step explanation:

Let

x ----> the length of each red rod in centimeters

y ----> the length of each blue rod in centimeters

we know that

3x=2y+2 ----> equation A

3y=4x+2 ----> equation B

Solve the system by graphing

Remember that the solution of the system of equations is the intersection point both graphs

using a graphing tool

The solution is the point (10,14)

see the attached figure

therefore

The length of each red rod is 10 cm and the length of each blue rod is 14 cm

3x+15=3(x+5) help please?
UkoKoshka [18]
3x+15=3(x+5)

3x+15=3x+15

3x-3x=15-15

Therefore x can be equal to any value.

Please help me find measure of angle LKM if measure of angle LKN = 145°​
natali 33 [55]

Answer:

56

Step-by-step explanation:

The thing to realize is that the total of both angles that have x in them is that they add to 145. That's given.

<LKM + <MKN = 145

2x + 10 + 4x - 3 = 145              Combine like terms

6x + 7 = 145                             Subtract 7 from both sides

6x = 138                                   Divide by 6

x = 138/6

x = 23

That's not the answer.

2x + 10 = <LKM

2*23 + 10 = <LKM

46 + 10 = <LKM

56 = <LKM

USPshnik [31]

Answer:

Step-by-step explanation:

Since this is not factorable, let's just complete the square:

x^2+6x=19\\x^2+6x+9=28\\(x+3)^2=28\\x+3=\sqrt{28}\\x=2\sqrt{7}-3
