Add the ratios together: 2 + 3 +4 = 9
Divide the total tips by 9:
77.40 / 9 = 8.60
Multiply each portion of the ratio by 8.60:
2 x 8.60 = 17.20
3 x 8.60 = 25.80
4 x 8.60 = 34.40
The ratios are in order of the people:
Paul got 17.20
Colin got 25.80
Brian got 34.40
Brian got 34.40 - 17.20 = 17.20 more than Paul
to solve this system I first multiplied the second equation by 2 to make the x coefficient equal. then I subtracted equation two from equation one. this eleminated the x. solving for y gave me y=0. then I put 0 back in the original equation and that gave me x=-4.
The relationship between lines KO and K’O’ is given as Line K'O' = 5 * line KO
<h3>What is a
transformation?</h3>
Transformation is the movement of a point from its initial point to a new location. Types of transformation are<em> reflection, rotation, translation and dilation.</em>
Dilation is the increase or decrease in size of a figure by a scale factor.
The larger figure was dilated using a scale factor of 5, hence:
Line K'O' = 5 * line KO
The relationship between lines KO and K’O’ is given as Line K'O' = 5 * line KO

Answer: 72
Step-by-step explanation: 80% x 90
8*9 is 72 = 90 x ➗80
80 percent * 90 =(80:100)* 90 =(80* 90):100 =7200:100 = 72
The answer is 53
