We divide the total set into several sub-sets (subgroups) that contain the exact same number of members. This way we know the number of total members by adding the number of total subsets.
<span>We simplify the equation to the form, which is simple to understand
<span>m/8-7=12
</span></span><span>Simplifying:
<span> + 0.125m-7=12
</span></span><span>We move all terms containing m to the left and all other terms to the right.
<span> + 0.125m=+12+7
We simplify left and right side of the equation.
<span> + 0.125m=+19
We divide both sides of the equation by 0.125 to get m.
<span>m=152
Hope this helps :)♥

Answer:
Step-by-step explanation:
5. a) ∠1 and ∠2 are remote interior angles of ∠ACD so that means that ∠ACD = ∠1 + ∠2
b) Because an exterior angle is the sum of its two remote interior angles it makes sense that an exterior angle is greater in measure than either of its remote interior angles.
6. BD = DB Reflexive property
∠3 = ∠5, ∠4 = ∠6 Alt. int. angles
ΔADB = ΔCDB ASA
7. AB = BC Def. of midpoint
∠1 = ∠2 Given
∠BAE = ∠CBD Corresponding angles
ΔBAE = ΔCBD ASA
∠D = ∠E CPCTC
