Lydia is having a party on Saturday. She decides to write a riddle on her invitations to describe her house number on Cypress St

ankoles [38]

Answer:

Lydia's address is Cypress Street is: 51823

Step-by-step explanation:

Represent the digit as ABCDE such that:

A = Ones

B = Tens

C = Hundred

D = Thousand

E = Ten Thousand

Analyzing the statements one after the other:

The tens digit is 6 less than 7.

$B = 7 - 6$

$B = 1$

The thousands digit is twice the digit in the tens place.

$D = 2B$

$D = 2 * 1$

$D = 2$

The hundreds digit is the greatest even number that is less than 10.

$C = 8$

The ones digit is the product of 5 and 1.

$A = 5 * 1$

$A = 5$

The ten thousands digit is the difference between the hundreds digit and the ones digit.

$E = C - A$

$E = 8 - 5$

$E = 3$

Lydia's address is Cypress Street is: 51823

Given the function f(x) = 6|x – 2| + 3, for what values of x is f(x) = 39

Nimfa-mama [501]

F(x) = 6 |x-2| + 3.....when f(x) = 39

39 = 6 |x-2| + 3
39 - 3 = 6 | x-2 |
36 = 6 |x-2|
36/6 = |x-2|
6 = |x-2|

x - 2 = 6
x = 6 + 2
x = 8

x - 2 = -6
x = -6 + 2
x = -4

answer : -4 and 8
