Answer:
The correct answer is A. a = 2s - b - c
Step-by-step explanation:
First you multiply 2 on both sides and you will end up with 2s = a + b + c.
Then to isolate a you would subtract both b and c from both sides of the equation as well to end up with your answer of a = 2s - b - c.
Answer:
x = c - b
Step-by-step explanation:
c = x + b
Subtract b on both sides,
c - b = x + b - b
c - b = x
x = c - b
Hence, solved.
The lowest common multiple is 216 (D)
From the second equation:-
x = 6 - 4y
Substitute this for x in the top equation
A clydesdale would drink about 840 gallons in 28 days time.
120/4 = 30 (gallons a day) x 28 (days time) = about 840
