Calculate percentage change

from V1 = 15 to V2 = 18

(V2−V1)|V1|×100

=(18−15)|15|×100

=315×100

=0.2×100

=20%change

I need to solve all answers
yan [13]

Answer:

Answers for 19, 20, 22, 24, and 25.

Step-by-step explanation:

19. 23x - 16 + 8x - 21 = 180  

    x = 7

    23 (7) - 16 = 7y - 23

    y = 24

20. 10x -17 = 8x + 1

     x = 9

    6y + 29 + 73 = 180

    y = 13

22. 8x - 35 + 6x - 5 + 3x - 1 = 180

      x = 13

24. m<R is 74

     m<Q is 32

25. m<E is 37

     m<G is 37

I didn't know the answers for all, but I hope this helps in some way!

With respect to the diagram, which relationship is false if ∠FEA is supplementary to ∠HGD?
Mama L [17]

The statement that is false with respect to the diagram given where angle FEA is stated to be supplementary to angle HGD, is:

A. measure of angle FEB + measure of angle HGD = 180°

<h3>What are Supplementary Angles?</h3>

By definition, supplementary angles are two angles that have a sum of 180 degrees when added together, that is, one is a supplement of the other.

Given the image below, we know the following:

Since angle FEA is supplementary to angle FEA would be congruent to angle HGC, and angle HGD is congruent to angle FEB. This is because, the supplement of angle

angle FEA + angle FEB - angle FEA + angle HGD = 180° - 180°. Therefore,

angle FEB = angle HGD.

In summary, from the options given, the statement that is false with respect to the diagram given where angle FEA is stated to be supplementary to angle HGD, is:

A. measure of angle FEB + measure of angle HGD = 180°
