1) £20
2) 18/4 * 7 = 31,5msquared
3) X= (3-1)/5 = 2/5 = 0.4
4) A(n) = 2 + 5n
5) t(3) = 6*3 + 2 = 20
Answer:
4 hours 33 minutes
Step-by-step explanation:
multiply the distance of each trip by the amount of trips taken to find the total distance traveled:
500x6=3000 miles
time=distance/speed:
3000/11= apro 273 mins
= 4 hours 33 minutes
Sat + Sun = 52
Sun = Sat + 8
Sat + Sat + 8 = 52
2Sat + 8 = 52
2Sat + 8-8 = 52-8
2Sat = 44
2Sat/2 = 44/2
Sat = 22
Sun = 22 + 8
Sun = 30
Check
Sat + Sun = 52
22 + 30 = 52
52 = 52
1, 4, 9, 16, 25, 36, and 49 because 1*1=1, 2*2=4, 3*3=9, 4*4=16, 5*5=25, 6*6=36, and 7*7=49
