<em><u>Answer:</u></em>
x = 8
<em><u>Step-by-step explanation:</u></em>
Okay, so with the info here, we know that angle RXS is 4x + 1, angle SXT is x + 9, and angle RXT is 50.
Angle RXT is angle RXS + angle SXT because it's on the diagram. So from
RXT = RXS + SXT, we can creat the equation:
50 = (4x + 1) + (x + 9) [Because we plug in the values]
So from here, we have to solve the equation:
50 = (4x + 1) + (x + 9)
First, we want to simplify everything so:
50 = 5x + 10
Then we want to isolate the variable so:
50 - 10 = 5x + 10 - 10
40 = 5x
40/5 = 5x/5
8 = x
<u>x = 8</u>
Given :
Plan A will cost $2.00 per song. Plan B will require a $15 joining fee and $1.49 per song.
To Find :
When will Plan A be a less expensive option for Aubrey? When will Plan B be a less expensive option for Aubrey?
Solution :
Let, after x songs Plan A will be less expensive.
So,
2x < 15 + 1.49x
0.01x < 15
x < 29.41 i.e x < 30
Before, 30 songs Plan A will be less expensive.
After, 30 songs Plan B will be less expensive.
Hence, this is the required solution.
