Answer:
27
Step-by-step explanation:
Given the ratio 3 : 9
and 9 : ?
note that 3 × 3 = 9, thus 9 × 3 = 27
3 : 9 = 9 : 27
Answer: Hello, Here you Answer......
132 km
Given that the relationship between kilometers and fuel is proportional, let the distance in km be k and the fuel be f:
thus:
kα cf
k=cf
where k is the constant of proportionality. Thus:
c=k/f
Pamela drove 99 km and used 9 liters;
∴k=99/9=11 km/liter
therefore distance covered is given by:
k=11f
hence the distance covered with 12 liters of fuel will be:
k=11×12
=132 km Hope this helps! (Brainly)♥
Step-by-step explanation:
3x + 1 = -14
3x = -14 - 1
3x = -15
x= -15÷3
x= -5
To find the slope of the graph you pick any piece of the line, and divide the vertical difference between its ends by the horizontal difference between its ends. If the graph is distance versus time then the slope represents the speed.
