the ages of mother and daughter are in the ratio of 5 : 3 if the age of mother is 50 years find the age of her daughter ​
netineya [11]

Answer:

30 years

Step-by-step explanation:

Forming Algebraic expressions and solving them to find the age.

Ratio of age of mother and daughter = 5 : 3

Age of mother = 5x

Age of daughter = 3x

It is given that mother's age is 50 years.

⇒ 5x = 50

Divide both sides by 5.

  x = 50÷5

 x = 10

Daughter's age = 3x

                          = 3*10

                         = 30 years

Solve the quadratic equation for x in the simplest equation -6x^2+15x+9=0
Alexus [3.1K]

Answer:

x = 3, -1/2

Step-by-step explanation:

Use the quadratic formula:  x = [-b ± √b² - 4ac]/2a

The square root sign should be over the entire expression b² - 4ac

In this problem, a = -6, b = 15, and c = 9

So, putting in those values, we get x = -15 ± √225+216, all divided by -12

Simplifying further, we get -15 ± 21 all divided by -12, or -36/-12 = 3 OR

6/-12 = -1/2
