. Express the ratios in its simplest form (a) 15:12 (b) 42:1
telo118 [61]

Answer:

See answers below

Step-by-step explanation:

Given the following ratios. We are to express them in their simplest forms

15:12

= 15/12

= (3*5)/(3*4)

= 3/3 * 5/4

= 5/4

b) 42:1

= 42/1

= 42

Given that  2:x :: 4:6​

2/x = 4/6

Cross multiply

4x = 2*6

4x = 12

x = 12/4

x = 3

Hence the value of x is 3

Angelica had 8 more pairs of shoes than her mom. Together they have 30 pairs of shoes. How many pair of shoes does each one have
MAVERICK [17]

Answer:

The answer to your question is Angelica 19, her mom = 11

Step-by-step explanation:

Data

Angelica has 8 more than her mother

total number of shoes = 30 pairs

The Number of pairs Angelica has = a = ?

The Number of pairs her mother has = m = ?

Process

1.- Write two equation that help to solve this problem

        a = m + 8                    Equation l

        a + m = 30                  Equation ll

2.- Solve the system of equations by substitution

Substitute equation l in equation ll

       (m + 8) + m = 30

-Solve for m

        m + 8 + m = 30

        2m = 30 - 8

        2m = 22

          m = 22/2

          m = 11

3.- Find a

          a = 11 + 8

          a = 19

4.- Conclusion

 Angelica has 19 pairs of shoes and her mom has 11
