What is the expression and value of “six less than the quotient of a number and two, increased by ten” when n = 8? StartFraction n Over 2 EndFraction minus 6 + 10; when n = 8, the value is 8.
6 minus StartFraction n Over 2 EndFraction + 10; when n = 8, the value is 12.
StartFraction n Over 2 EndFraction minus 6 + 10; when n = 8, the value is 11.
6 minus StartFraction n Over 2 EndFraction + 10; when n = 8, the value is 9.

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.

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 -
