If a,b,c,d are in continuous proportion then prove that (c+a) (c+d) = (b+c) (b+d)​
sesenic [268]

Answer:

We must prove that (c+a)(c+d) = (b+c)(b+d)

  1. Let us use principles from mathematical induction
  2. \frac{a}{b}  =  \frac{b}{c}  =  \frac{c}{d}  = x
  3. a=bx , b=cx, c=dx
  4. a+c = b + c
  5. c +d = b + d
  6. Such that (a+c)(c+d)=(b+c)(b+d)

Pencils come in packages of 10.Erasers come in packages of 12. Phillips wants to purpose the smallest number of pencils and eras
balandron [24]

Answer:

The answer to your question is:

Packages of pencils = 6

Packages of erasers = 5

Step-by-step explanation:

Data

Pencils = 10/package

Erasers = 12 / package

Process

Find the least common factor of 10 and 12

                                    10     12     2

                                     5       6     2

                                     5       3     3

                                     5        1    5

                                      1

LCF = 2 x 2 x 3 x 5 = 60

Finally divide 60 by the number of pencils or erasers in each package

Packages of pencils = 60/10 = 6

Packages of erasers = 60/12 = 5
