Solution:

<u>Note that:</u>

  • 4/7 = 10/x

To find the solution to the proportion, we will need to simplify the equation (4/7 = 10/x)

  • 4/7 = 10/x
  • => 4x = 70
  • => x = 70/4 = 35/2 = 17.5.

Hoped this helped!

Evaluate the expression for x = 3 y= 1/3 and z= 5. 12 x - 3y over 4 x - Z​
Zepler [3.9K]

Answer:

35.786

12(3) - 3(1/2)/4(3) - 5

This is then further simplified to:

36 - 1.5/7

And when you divide 1.5 by 7, the number (rounded) is .214.

Thus, subtract, and gain the final answer of 35.786.

Hope this helps!

Explain how System 1 becomes equivalent to System 2.
LenKa [72]

Answer:

In the procedure

Step-by-step explanation:

we have

<em>System 1</em>

Ax+By=C -----> equation A

Lx+My=N -----> equation B

<em>step 1</em>

Multiply equation B by -1 both sides

(-1)*(Lx+My=)N*(-1)

-Lx-My=-N ------> equation C

<em>step 2</em>

Adds equation A and equation C

Ax+By=C

-Lx-My=-N

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

Ax-Lx+By-My=C-N

(A-L)x+(B-M)y=C-N -----> equation D

step 3

An equivalent system (System 2) is formed with

Ax+By=C -----> equation A

(A-L)x+(B-M)y=C-N -----> equation D
