A jar is filled with quarters and nickels in the ratio 1 2/5 to 2 1/3. If there are 24 quarters in the jar, what is the ratio in dollar value of quarters to that of the nickels???
Answers
Answer:
3 : 1
Step-by-step explanation:
The ratio of coins is ...
1 2/5 : 2 1/3 = 7/5 : 7/3 = 3 : 5
The quarters have 5 times the dollar value of nickels, so the ratio of dollar values is ...
5(3) : 5 = 3 : 1
The quarters have 3 times the dollar value of the nickels.
__
Additional comment
The number of nickels is 5/3 times the number of quarters, so is 5/3(24) = 40.
The dollar value of the quarters is 24($0.25) = $6.
The dollar value of the nickels is 40($0.05) = $2.
As above, the ratio of dollar values is 6:2 = 3 : 1.

Write an equation of the line that passes through 9,2 and is parallel to the line y=5/3x+9
Answers
Answer:
Equation: I believe its y=5/3x-13
Step-by-step explanation:
In the "y=5/3x+9" equation, 5/3 is the slope. You then take the slope (5/3) and the points (9,2) and add it to the equation "y+y1=m(x-x1)":
y-y1=m(x-x1)
distribute 5/3: y-2=5/3(x-9)
y-2=5/3x-45/3
y-2=5/3x-15
-add 2 on both sides-
y=5/3x-13

If JL is the whole (75), you add JK (9x+3) and KL (5x+2). 9x+3+5x+2=75. Add like terms first. 14x+5=75. Subtract 5 from both sides. 14x=70. Divide by 14 from both sides. X=5. Now plug X=5 into your equation (KL: 5x+2). 5(5)+2= 27
