If 7x=3y and 5y=7z then X/Z?

Mathematics
1 answer:
Aleks04 [339]3 years ago
7 0

Answer:

3/5=x/z

Step-by-step explanation:

7x=3y

7(3)=3(7)

21=21

5y=7z

5(7)=7z (plug in the seven from the first step)

35=7z

then divide both sides by 7

5=z

therefore, X/Z=3/5

In the right hand side, you're multiplying again 7.8 by a mysterious number.

Every number remains unchanged when multiplied by 1, so the answer is 3.6

Find the value for x​
d1i1m1o1n [39]

Answer:

Value of x --> 15°

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

(2x + 60°) and 6x lie on a straight line. So, they form a linear pair. Their sum gives 180°.

---> (2x + 60°) + 6x = 180°

     2x + 60° + 6x = 180°

     8x + 60° = 180°

     8x = 180°- 60°

     8x = 120

      x = \frac{120}{8}

<h3><u>x equals 15°</u></h3>
