Simplify:
(7/9)/(3/5)
Multiply the numerator by the reciprocal of the denominator, (7/9)/(3/5) = 7/9×5/3:
(7×5)/(9×3)
9×3 = 27:
(7×5)/27
7×5 = 35:
Answer: 35/27
Answer:
546
Step-by-step explanation:
At the bank, Derek made 7 withdrawals, each in the same amount. His brother, John, made 5 withdrawls, each in the same amount.
Let x be the amount of one of Derek's withdrawals
Each of John's withdrawals was $5 more than each withdrawal that Derek made.
x + 5 is t the amount of one of John's withdrawals
Derek made 7 withdrawals
So amount withdraw 7 times = 7x
John made 5 withdrawals
So amount withdraw 5 times = 5(x+5)
Both Derek and John withdrew the same amount of money in the end
(A) 7x = 5(x+5)
(B) Solve for x
7x = 5x + 25
Subtract 5x from both sides
2x = 25
Divide by 2
x = 12.5
(C) check your solution
we plug in 12.5 for x in 7x= 5x + 25
7(12.5) = 5(12.5) + 25
87.5 = 62.5+ 25
87.5 = 87.5
(D) Each brother withdrawal 87.5 dollars
Answer:
.
Step-by-step explanation:
According to the Rational Root Theorem, the potential roots of a polynomial are
where, p is a factor of constant and q is a factor of leading term.
The given polynomial is
Here, 9 is the leading term and 7 is constant.
Factors of 9 are ±1, ±3, ±9.
Factors of 7 are ±1, ±7.
Using rational root theorem, the rational or potential roots are
Therefore, the potential root of f(x) are .
