Question

what must be added to each of the number 4, 7, 26, 40 to get the number which are in proportion?​

Answer 1

Answer:

Step-by-step explanation:

1.(4+x):(7+x)::(26+x):(40+x)

(4+x)(40+x)=(26+x)(7+x) (PRODUCT OF MEANS = PRODUCT OF EXTREMES)

2.160+40x+4x+x^2=182+26x+7x+x^2

160+44x=182+33x ( x ^2 get cancelled)

3. 44x- 33x=182- 160

11x=22

x= 22/11

x=2
