Answer:
carbon footprint
7.7 tons
Step-by-step explanation:
Given that,
carbon dioxide produced by a car over 7 year period = 53.5 tons
To find,
carbon footprint <em>(tons of carbon dioxide per year)</em>
7 years ------> 53.5 tons
1 year -------> 53.9/7 tons
= 7.7 tons
tons of carbon dioxide produced per year = 7.7
Answer:
it is 20

12-8=4 so we add the 4 to the 12 and it gives us 16...then 16 rounded off to the nearest 10 is 20
Answer:
x<8
Step-by-step explanation:
divide each term by -8 and simplify
Answer:
y = -4x + 1
Step-by-step explanation:
The line passes through points (-5,21) and (-4,15)
Slope(m) = change in y ÷ change in x
m = 
m =
= -36/9 = -4
Taking another point (x,y) on the line and comparing it with point (4,-15):
-4 = 
Cross multiplying gives:
y + 15 = -4x + 16
y = -4x + 1
