Answer:
Step-by-step explanation:
Let be "s" the length in meters of the short piece and "l" the lenght in meters of the long piece.
Set up a system of equations:
Apply the Substitution Method to solve the system. Substitute the second equation into the first equation and solve for "l":
Susbstitute the value of "l" into the second equation in order to find the value of "s". This is:
The answer is 47.5 feet. Hope I helped!
I think this is it, but i’m not sure about the last one
1/7 is your answer. It can't be reduced any further. If there is supposed to be a problem, next time, add it.
Answer:
The original number was 54.5.
Step-by-step explanation:
If a number is increased by 2.8%, then it is 102.8% of it's original number.
In mathematics, "of" in virtually all cases means "multiplied by".
Therefore, we do the opposite:
1. Convert to a decimal.
102.8% = 1.028
2. Divide by the decimal.
3. Round it to the nearest tenth.
54.47 rounds to 54.5.
