The system of linear equations that relates x and y:
x= 15 + y
5 x = 2 y+ 525
We will solve this system using substitution method:
5(15 + y)=2 y + 525
75 + 5 y = 2 y + 525
5 y - 2 y = 525 - 75
3 y = 450, y = 450 : 3 y = 150
x = 15 + y x = 15 + 150 x = 165
Answer: Aaron´s height is 165 cm and Peter´s height is 150 cm.
His answer is correct because if you have the pie chart, it shows the percentage. <span>he did 45 times 3 to get the 135 because he though since 10% is 45 people he could multiply by 3 & get his answer.
Hope this helped.</span>
<em>b</em> = amount of bantha milk
<em>t</em> = amount of tauntaun milk
<em>b</em> + <em>t</em> = 350
0.16 <em>b</em> + 0.09 <em>t</em> = 0.12(<em>b</em> + <em>t</em>) = 42
<em>t</em> = 350 - <em>b</em>
0.16 <em>b</em> + 0.09 (350 - <em>b</em>) = 42
0.16 <em>b</em> + 31.5 - 0.09 <em>b</em> = 42
0.07 <em>b</em> = 10.5
<em>b</em> = 150
<em>t</em> = 200
