a= 40
Step-by-step explanation:
-5a + 7.5a - 25 = 53.2 + 21.8

add 25 on both sides: 2.5a = 100
divide both sides by 2.5: a = 40
1.x×2+24=0
2x=0-24
2x=-24
x=-24/2
x=-12.
9.x×2-9x+3=0
2x-9x=0-3
-7x=-3
x=-3/-7
11.x×2+4x+13=0
2x+4x=0-13
6x=-13
x=-13/6
Hope it is correct and helps u.
The percent of error can be found by dividing the difference in weights by the predicted weight.
