Asap offering 10 points ruth mason received a 4.3% merit increase and a 3.25% cost-of-living increase after her quarterly review. her new weekly salary was $ 688.32. what was her weekly salary prior to the increases? (enter the amount in dollars and cents) use the following equation to you new salary = x + cost of living increase + merit increase

Just did one just like it

688.32 = x + .043 x + .0325 x = 1.0755 x

x = 688.32/1.0755 = $640.00

$640.00

Check: 640(1+.043+.0325)= 688.32 good

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.

i googled it and this is what i got i don't know how it is. sorry.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
