Answer:
The answer is :
so, type 190 in the box
Step-by-step explanation:
Notice that there are three right angle triangles in the image given. In order to create equations associated with the Pythagorean Theorem for the three triangles, we add the letters x and z to identify two sides that are missing information. Please see attached image for reference.
In the small right angle triangle on the right, the Pythagorean theorem tells us:
In the larger triangle :
In the small triangle on the left:
and in this last equation we can substitute the z-squared and the x-squared by the expressions we got before in the other two equations:
Then to solve for "y" we apply the square root:
Amount of tip she gave,
Amount of tax given :
So, total amount she paid is :
Total = Actual cost + Tip + Tax
Total = $(15 + 3 + 1.35 )
Total = $19.35 .
Therefore, total amount she paid is $19.35 .
Hence, this is the required solution.

Answer:
Step-by-step explanation:
-0.5(3x + 5) and -1.5x + 2.5
-0.5(3x + 5)...distribute the -0.5 thru the parenthesis
-1.5x - 2.5
no, these are not equivalent.... one is -1.5x + 2.5 and the other is -1.5x - 2.5....not the same
21x + 28 = 156 - 2
21x = 154 - 28
21x/21 = 126/21
X = 6
