Answer:

Charlene earns $700 per week

Kristi earns $550 per week

Sascha earns $800 per week

Step-by-step explanation:

Since Kristi earns 150 less than Charlene which is 100 less than Sascha, this is equal to the value of Sascha minus 250. We put this in the equation as s-250.

Together, they all earn $2050, so we must equal this to Charlene's value k+150, plus Kristi's value k, plus Sascha's value s.

<em>k+150+k+s=2050</em>

The next step here is to put the variables on one side and to put the numeric values on the other.

2k+s=1900

Like we said before, Kristi's value is equal to s-250, so we would replace k with that expression.

2(s-250)+s=1900

2s-500+s=1900

3s=2400

s= 800

We now have Sandra's weekly pay, which we can use to find the others' pay.

c= s-100

c= 800-100

c= 700

k= c-150

k= 700-150

k= 550

Solve negative one fifth times the quantity 3 minus 12 times the quantity one third squared end quantity end quantity.
katrin [286]

The solution to the given equation is -87/45

<h3>Product of expressions</h3>

Given the following expression that represents the word problem as;

-1/5 * 3 - 12(1/3)^2

Using the PEMDAS rule, the parenthesis and exponent will come first to have;

-1/5 * 3 - 12(1/3)^2 = -1/5 * 3 - 12(1/9)

Then multiplication

-1/5 * 3 - 12(1/9) =. -3/5 - 12/9

Find the difference

-1/5 * 3 - 12(1/9) = -27-60/45

-1/5 * 3 - 12(1/9) = -87/45

Hence the solution to the given equation is -87/45
