Answer:
$36.69
Step-by-step explanation:
Okay, so let's first write the equation:
2.59*10 + 3d = 135.97
Now, let's work on isolating d by first simplifying the equation:
25.9 + 3d = 135.97
25.9 + 3d - 25.9 = 135.97 - 25.9
3d = 110.07
3d/3 = 110.07/3
d = 36.69
Okay, now let's check:
2.59*10 + 3*36.69 = 135.97
25.9 + 110.07 = 135.97
135.97 = 135.97
Okay, so so it costs $36.69 per pair of shoe.
300 people, I think. One fourth of 1,200 is 300.
If you want to find the product it would be 6x^2-7xy^2+y^4
m < x = (m arc AD + m arc BC) / 2
= (140 + 90) / 2
= 230/2
= 115 degrees answer
