The answer is twenty-eight coins in all, or seven of each coin.
Seventeen-thousand and one hundred 6 thousandths written in standard form would be 17,000.106
Hope this helped =)
Let the two numbers be represented by x and y. The problem statement gives rise to two sets of equations.
x - y = 0.6
y/x = 0.6 . . . . . . . assuming x is the larger of the two numbers
or
x/y = 0.6 . . . . . . . assuming y has the larger magnitude
The solution of the first pair of equations is
(x, y) = (1.5, 0.9)
The solution of the first and last equations is
(x, y) = (-0.9, -1.5)
The pairs of numbers could be {0.9, 1.5} or {-1.5, -0.9}.
Answer:3: If a linear system has the same number of equations and variables, then it must have a unique solution.
