Answer:
The answer is 6
Step-by-step explanation:
A=½(b1 + b2) h
we substitute
Area=75
the two bases are 10 and 15
75=½(10+15) h
75=½(25)h
75=(1*25/2)h
75= 25h/2
75/1= 25h/2
25h*1= 75*2
25h= 150
we divide by 25
25h/25= 150/25
h=6
Move the 8 over
-x=3x-8
Move the 3x over
-x-3x=8
-4x=8
Divide by -4
x=-2
Answer:
(i)= 45 KPH, (ii) = 251 miles
Step-by-step explanation:
'Per' essentially means divide. Thus, to find Kilometres per hour, divide 270 by 6= 45. The bus is travelling at 45 KPH.
Then, to see how far a nine hour trip would cover, distance = speed * time = 251 miles.
