Answer:
9 quarters and 7 dimes
Step-by-step explanation:
1 quarter = $0.25
1 dime = $0.10
9 (0.25) = $2.25
7 (0.10) = $0.70
2.25 + 0.70 = $2.95
Let’s make x = # of nickels. Then 3x = # of dimes and 3x+6 = # of pennies. A nickel is 5 cents, a dime is 10 cents and a penny is 1 cent.
The money she has should be .05(x) + .10(3x) + .01(3x+6) = 4.62 or to make it simpler: 5(x) + 10(3x) + 1(3x+6) = 462.
5x + 30x + 3x + 6 = 462
38x + 6 = 462
38x = 456
x = 12.
So she has 12 nickels (12 * $0.05 = $0.60), 36 dimes (36 * $0.10 = $3.60) and 42 pennies (42 * $0.01 = $0.42). $3.60 + $0.60 + $0.42 = $4.62.
X= 30/r is the answer because if you divide both sides by r you are left with x=30/r because you cant divide 30 by r

The value of x is and
Step-by-step explanation:
The equation is
Subtracting by on both sides,
Taking LCM,
Multiplying by 3x on both sides,
Dividing by (-) on both sides,
Using quadratic formula, we can solve for x.
Taking out common term 2, we get,
Thus, the value of x is and
