Write the standard form of the equation y+4=12/7(x-1)
Goshia [24]
This is the eqn of a str line.    <span>y+4=12/7(x-1) would be clearer if written as

</span><span>y+4=(12/7)(x-1).     y+4 = (12/7)x - 12/7.  

Multiply all terms by 7 to remove the fractions:  7(y+4) = 12x - 12.

Complete the multiplication:                            7y + 28 = 12x - 12.

Arrange the x and y terms on the left side and the constants on the right:

-12x + 7y = -40.  This is standard form.  Some people might disagree and say that -12x + 7y + 40 is standard form.  They are equivalent.

If you drew a marble from a bag containing 24 marbles and you had a 1/3 probability of drawing a red marble, how many red marble
Masja [62]
Hello there.

Question: <span>If you drew a marble from a bag containing 24 marbles and you had a 1/3 probability of drawing a red marble, How many red marbles are in the bag?

Answer: 1/3 is just a simplified version of the original fraction.
To find this out, get the denominator to the total of 24.
24 / 3 = 8.
You multiply the bottom by 8 therefore you need to do the same to the top.

In short, Your answer is </span>\frac{8}{24}.
The number of red marbles is 8.

Hope This Helps You!
