15 + 2x - 4 = 9x + 11 - 7x
2x + 11 = 2x + 11
always true

2x + 3(4x - 1) = 2(5x + 3) + 4x
2x + 12x - 3 = 10x + 6 + 4x
14x - 3 = 14x + 6
never true

Answer:

  $4.00

Step-by-step explanation:

We assume the price is proportional to the quantity of oranges. If p is the desired price in dollars, we want ...

  p/8 = 0.25/(1/2)

  p = 8(0.50) = 4.00 . . . . multiply by 8, simplify

8 kg of oranges would cost $4.00.

scoundrel [369]

Step-by-step explanation:

solution,

given

DF = 42

DE = 7x+1

EF = 4x-3

DE = ?

here,

or, DF = DE +EF

or, 42 = 7x+1+4x-3

or, 42 = 11x-2

or, 42+2 = 11x

or, 44/11 = x

or, 4 = x

then,

replacing value of x in DE

DE = 7x+1

= 7*4+1

= 28+1

= 29
