Answer:
The volume each of the four barrels of the same size will be at least 47.5 liters.
Step-by-step explanation:
Let the volume of each of the four barrels is v liters.
Now, the amount of water that can be held in the fifth barrel is 10 liters. The total capacity of holding water for the 5 barrels combines is at least 200 liters.
So, from the above-given information, we can write the inequality to determine the volume of each of the four barrels will be
10 + 4v ≥ 200
Solving this we get,
4v ≥ 190
⇒ v ≥ 47.5
Therefore, the volume each of the four barrels of the same size will be at least 47.5 liters. (Answer)
Answer:
A = 3
B = -5
C = 1
C = -6
Step-by-step explanation:
Factors of 30:
10 3
15 2
5 6
Using positives or negatives of these numbers you need to find two that'll satisfy the equation
A is known to be 3 and C is known to be 1 because the factors of 3 are only 1 and 3.
After some trial and error we end up with
(3x-5)(x-6)
We know this will work because hen you multiply it out you get
3x^2-18x-5x+30
simplify
3x^2 -23x + 30
And this is the original equation
Answer: A = 216; B = 35
Step-by-step explanation:
Based on the information given in the question, we can then make it into a mathematical equation. This will be:
A + B = 251 ....... i
A - B = 181 ....... ii
From equation i,
A = 251 - B
Put the value of A into equation ii
A - B = 181
(251 - B) - B = 181
251 - B - B = 181
251 - 2B = 181
2B = 251 - 181
2B = 70
B = 70/2
B = 35
Since A = 251 - B
A = 251 - 35
A = 216
