Jim and Carla are scuba diving. Jim started out 8 feet below the surface. He descended 19 feet, rose 3 feet, and descended 11 more feet. Then he rested. Carla started out at the surface. She descended 18 feet, rose 3 feet, and descended another 19 feet. Then she rested. Which person rested at a greater depth? Complete the explanation. Jim rested at feet below the surface while Carla rested at feet below the surface. Therefore (select) rested at a greater depth.

answer: a

step-by-step explanation:

10.2 units

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 -

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.

where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically
