Answer:
AC = 2x - 13 Cm
BC = 3x + 4 Cm
AB = 36 Cm
AB = AC + BC
BC = AB - AC
= 36 - (2x - 13)
= 36 - 2x + 13
= 49 - 2x
but, BC = 3x + 4
so equating both the equation we get
3x + 4 = 49 - 2x
3x + 2x = 49 + 4
5x = 53
x = 53/5
x = 10.6
BC = 49- 10.6*2
= 49- 21.2
= 27.8 CM
If the answer is above 1/2 inch round it to 1 inch, if it is below 1/2 inch round it to 0, or the nearest number below it....hope it helps

Answer:
1/2
Step-by-step explanation:
5/10 houses gave her chocolate
if you simplify 5/10 by dividing by both the top and bottom by 5 to get 1/2
Answer:
See below
Step-by-step explanation:
The first one 'cubes' the denominator AND the numerator:
(-2/5)^3 = -2/5 * -2/5 * -2/5 = -8/125
The second one 'cubes' only the denominator:
-2/5^3 = -2 / (5 * 5 * 5) = - 2 / 125
