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

I might be wrong- but its worth a try ;-;

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.

__

There are a few different ways to compute the ratio of fractions. The one we used here may be a little unusual. All are equivalent.

Select each pair of equivalent numbers. PLS HELP DUE TMR AND I DONT HOW TO SOLVE IT, PLS SHOW HOW U SET IT UP

Answers

The pairs that are equivalent to each other are 40/1000 and 40%, 6/5 and 120%, 1/8 and 12.5% . They are the correct answers because if we divide for example 6/5 , we would get 1.2 and to turn a decimal into a percent we have to move the decimal point 2 times to the right meaning that the percentage would be 120% and you just do that for all!
