Find the distance between the two points. (2, 4), (7,2)
The distance between the two points is
units.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

hello! just here for points! though i wish i knew!

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 -
