Can someone help me pleaseee

9514 1404 393

  £374

Step-by-step explanation:

Let d represent Carol's decreased wage, w represent its original value, and i represent that wage with an increase.

We want to find i = w(1 +10%) = 1.10w.

We have d = w(1 -10%) = 0.90w.

Solving the latter for w, we find ...

  w = d/0.90

Substituting this into the expression for i, we get ...

  i = 1.10(d/0.90) = d(1.10/0.90) = d(11/9)

Then the increased wage would have been ...

  i = £306(11/9) = £374

Had Carol received a 10% increase, her weekly wage would be £374.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
