heres a quick tip In these kind of Questions count the number of "-" and if they are odd then your answer will be -X if it is even the the anwer will be +X (X can be any number) so the answer will be like
-10x=-5---->x=-5/-10--->x=5/10--->x=1/2--->x=0.5
Answer: 4x − 2y = 6 . . . . . (1)
2x + y = 5 . . . . . (2)
(2) x 2 => 4x + 2y = 10 . . . . . (3)
(1) - (3) gives: -4y = -4
y = -4/-4 = 1
From (2), 2x + 1 = 5 => 2x = 5 -1 = 4
x = 4/2 = 2
Solution is (2, 1)
Substituting the solution into the options gives that
−4x − 2y = 10
−4y = 4 −4x
has the same solution.
hope this helped!! :)
Answer:
2.6 hr
Step-by-step explanation:
distance / rate = time
rate = 75 + 95 = 170 mile/hr
distance = 442 miles
442 miles / 170 mile/hr = 2.6 hr
Answer:
Large amount of reduction occurs.
Step-by-step explanation:
Large amount of reduction occurs in the harmful emissions if the family used public transportation for school and work, used energy-efficient lightbulbs in your house, switched to a vegetarian or vegan diet, etc because these activities produces large amount of carbondioxide gas. 36.44 billion metric tons of carbondioxide gas is produced per year due to human activities so due to reduction in emission about 12 billion metric tons of carbondioxide is produced which is 1/3 of the total emission. these steps can neutralize carbon footprint emissions because only the nature emitted carbondioxide gas in the atmosphere which create balance on the earth.
