B) John returns from holiday with these notes.
ivolga24 [154]

Answer:

£290.70

Step-by-step explanation:

Number of notes of $50 = 5

Total value = 50 × 5 = $250

Number of notes of $20 = 2

Total value = 20 × 2 = $40

Number of notes of $10 = 7

Total value = 10 × 7 = $70

Number of notes of $5 = 3

Total value = 5 × 3 = $15

Total value of all notes with John = 250 + 40 + 70 + 15

                                                        = $375

Since, $1.29 = £1

Therefore, $1 = £\frac{1}{1.29}

Therefore, $375 = £ \frac{375}{1.29}

                           = £290.70

The width of a rectangle is 2 less than twice the length, x. If the perimeter is 44, what is the width?
Butoxors [25]

Take the length as 'x'

Width = 2x - 2

Perimeter = 44 [ Formula = 2(l + w) ]

2 (l + w) = 44

2 (x + 2x - 2) = 44

2 (3x - 2) = 44

6x - 4 = 44

6x = 44 + 4

6x = 48

x = 48/6

<u>x </u><u>=</u><u> </u><u>8</u> => length

Width = 2x - 2 = 2(8) - 2 = <u>1</u><u>4</u><u> </u><u>units.</u>

Hope it helps!
