Answer:

5 years ago

Let Kelly's age be x

Jake's age is 4x

5 years later

Kelly's age is x + 5

Jake's age is 4x+5

The sum of both their ages is 60. The equation will be

x + 5 + 4x + 5 = 60

5x + 10 = 60

5x = 60 - 10

x = 50/5 = 10

So Kelly is (10 + 5) 15 years old.

Jake is (4*10 + 5) = 45 years old

Find all possible values of the expression 1/y if: .125
34kurt

Answer:

The possible values for 1/y of the expression 0.125 < y < 0.25 are in the range

4 < 1/y < 8

Step-by-step explanation:

The given information are;

The range of values of y are 0.125 < y < 0.25, therefore, we have;

The boundaries of the function, y are 0.125 and 0.25

The inverse of the boundaries of the function, y are 1/0.125 = 8 and 1/0.24 = 4

Therefore;

The limits of the inverse of the function y are ;

The inequality that represents 1/y is therefore;

1/0.25 < 1/y < 1/0.125 or 4 < 1/y < 8

The possible values of 1/y for the expression 0.125 < y < 0.25 are therefore;

4 < 1/y < 8.

if b = the number of blue bikes , which algebraic expression represent the phrase below ? the sum of the number of blue bikes an
Yanka [14]

The answer would be the algebraic expression, b + 9. The translation here is b is representing the number of blue bikes then you needed to add the 9 which represents the 9 red bikes. The two is added together, to get the total of those red and blue bikes which we are looking for.
