Arun is twice as old as Shreet 5 years ago his age was three times shree age find their present ages​
Mariulka [41]

Answer:  Arun is now 20, Shree is 10 years old

Step-by-step explanation:  

In the system of equations Arun's age is a. Shree is s

a = 2s .(current age equation)  Subtract 5 from each for five years ago,

a-5 = 3(s-5) . Substitute 2s for a in the second equation

2s -5 = 3(s-5)  distribute and reorganize

2s-5 = 3s -15 .   15 - 5 = 3s - 2s

10 = s .  Substitute into the first equation to find a

a = 2(10)

a = 20

5 years ago  Shree was 5 and Arun was 15

Dr. E. Quation says the Infant Mortality Rate of Korea shown by the expression; 7(m + 3) - 2. Is equal to his criminal success r
GarryVolchara [31]

Answer:

The infant mortality rate in Korea based on equality provided is:

  • 1.8

Step-by-step explanation:

Since the text mentions that the infant mortality rate in Korea is equal to the criminal success rate, the two expressions must equalize and clear the variable m, which is the rate in each of the expressions:

  • 7 (m + 3) - 2 = 8m + 17.2
  • 7m + 21 - 2 = 8m + 17.2
  • 7m + 19 = 8m + 17.2
  • 19 - 17.2 = 8m - 7m
  • 1.8 = m

As you can see, once the equality of the expressions is solved, <u>a rate of 1.8</u> is obtained.
