Answer:

$28.77

Step-by-step explanation:

What you do is the coupon for 10% off first which equaled 2.997, but you have to round to $3.00.

You minus 3*9.99 which equals $29.97 and $3.00 to get $26.97.

You then times $29.97 by 6% to get 1.80.

You then add it to $26.97.

You get $28.77.

Someone please help me I don’t know this :(
Shalnov [3]

Answer:

  x = 10; WX = 5; HJ = 10

Step-by-step explanation:

The hash marks indicate that points W and X are midpoints of their respective segments. That makes WX a midline of the triangle. The midline is always half the length of the base (HJ). We can use this fact to write an equation relating the lengths.

  HJ = 2·WX

  x = 2(x -5) . . . .substitute the given expressions

  x = 2x -10 . . . . eliminate parentheses

  10 = x . . . . . . . add 10-x to both sides

This value of x tells you that ...

  HJ = x = 10

  WX = x -5 = 5

Ganezh [65]
You would first add the two parts of the ratio to get ten, then divide 120 by ten to get 12. This means that each part of the ratio is worth 12 dollars, so to get the helper’s salary you would multiply 12 by three to get a total of 36.
