Answer:
Step-by-step explanation:
21-26. a = v - u / t
=> a = 47 - 19 / 5
=> a = 28 / 5
=> a = 5.6 m/s²
27-32. avg. speed = distance / time
=> 40 m / 10 s
=> 4 m/s
33-38. velocity = distance / time
=> v = 150 / 40
=> v = 15 / 4
=> v = 3.75 m/s
Answer:
; k=25

7 less than 25 (or K) is 18.
Um...4 times the sum of xy.....
4(x + y)
turn each number into an improper fraction
27 1/2 = (2*27+1 )/2 = 55/2
2 1/4 = (4*2+1)/4 = 9/4
55/2 divided by 9/4
copy dot flip
55/2 * 4/9
220/18
110/9 12*9 = 108
12 2/9 weeks
or if we round 13 weeks
