the answer is 2.86 dollars because it is 2.8 times 2.55 and subtract that from 10.
Find their lcm which is 4m then multiply
8m=44
m=44/8 or 5.5
It would be 50
130+180= 310
360-310= 50
You get 180 from the missing side by 70 that becomes 180.
1st:x
2nd x+2
3rd: x+4
(x)+(x+2) = 3(x+4)-31
distribute
2x+2 = 3x+12-31
2x+2 =3x-19
subtract 2x from each side
2 = x-19
add 19 to each side
21 =x
Answer: 21,23,25
G(x)= x-1
Hope this helps!
