James is older than benito. benito is younger than mariana. mariana is younger than james. describe how to
plot points on a number line that represent the ages of benito, b, mariana, m, and james, j.
can someone me write this

First Statement

 James is older than Benito.

→Age of James > Age of Benito--------(1)

Second Statement

  Benito is younger than Mariana.

→Age of Mariana > Age of Benito----------(2)

Third Statement

Mariana is younger than James.

→Age of James > Age of Mariana-----------(3)

Equating (1),(2) and (3)

→Age of James(J) > Age of Mariana(M)>Age of Benito(B)

⇒James will be farthest from right side of number line, that is Farthest distance from point 0(Zero), then Second Farthest from point 0" is Mariana, and then Third one will be Benito, nearest from point "0".

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
