4x=-4r+2d for x.
g=4ca-3ba for a.

            g

a =

        4c - 3b

Step-by-step explanation:

To solve 4x=-4r+2d for x, divide both sides by 4, obtaining:

x = - r + (1/2)d

To solve g = 4ac - 3ab for a, first factor a out of 4ac - 3ab, obtaining

g = a(4c - 3b).  Next, isolate a by dividing both sides by 4c - 3b:

            g

a =

        4c - 3b

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
