first part: rearrange to make y the subject.

y = (-63*9)/(9*x)

second part: "then find the value of Y for the given value of X", i.e. substitute x for 5 in the equation and find the value it gives for y:

y = (-63*9)/(9* 5) = ?

there are 280 female workers and 140 male workers working in a factory.3/5 of the workers are foreign workers and 1/2 of the foreign workers are female.calculate how many local workers in the factory are female.

First, find the total number of workers. (280 + 140 = 420)
Three fifths of this total are foreign. (420 * 3/5 = 252)
Half of the foreign workers are female. (252/2 = 126)
Since 126 of the 280 female workers are foreign, the remainder must be local. (280 - 126 = 154)

7y+4=3-2y

First, get all of the "y's" on one side of the equation
7y + 4 (+ 2y) = 3 - 2y (+ 2y)

Now, get the non-y factors on the other side of the equation
9y + 4 (- 4) = 3 (- 4)

You are left with
9y = -1

So,
y = - 1/9

12000(1.01125)2^5

12000 * 1.01125 * 2^5 = 12000 * 1.01125 * 32 = 388320

First, find the least common denominator for 2,3,6, and 18. That would be 18

Then, convert each of the fractions to have 18 as the denominator,
5/6 = 15/18 (5*3)/(6*3)
7/18 = 7/18 (no conversion needed for this one)
2/3 = 12/18 (2*6)/(3*6)
1/2 = 9/18 (1*9)/(2*9)

Now, add the converted fractions,
15/18 + 7/18 + 12/18 + 9/18 = 43/18 = 2 7/18
