Step-by-step explanation:
20)
n=-7
p=-6
we have:
21) mp-(p-(m-n))
m= -1 n=-6 p=-10
-1*-10-(-10-(-1-(-6)))
10-(-10-(5))
10-(-15)
10+15=25

The slope of the line is A, -1/2
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 = £
Therefore, $375 = £
= £290.70
