Answer:

d = -9

Step-by-step explanation:

Step 1: Write equation

-72 = 8d

Step 2: Divide both sides by 8

d = -9

Step 3: Check

<em>Plug in d to verify it's a solution.</em>

-72 = 8(-9)

-72 = -72

D=-9

-72=8d
they are both multiples of 8, so divide both sides by 8 abs you are left with:
-9=d
to check it, you can do the reverse or substitute the value of d into the equation, so -72=8(-9)
-72=-72

hope this helps :)

Lisa, Juan and isaac equally shared 1/2 of a cake which fraction of the whole cake did each of them recieve

IgorLugansk [536]

Answer:

Each will receive $\frac{1}{6}th$ of the cake.

Step-by-step explanation:

Let the amount of cake = c

Lisa, Juan and Isaac are the persons who are sharing half of a cake equally.

Number of persons = 3

Part of the cake shared = $\frac{c}{2}$

Fraction of the cake shared by each = $\frac{\text{Amount of cake shared}}{\text{Number of persons who shared}}$

= $\frac{\frac{1}{2}c}{3}$

= $\frac{1}{6}c$

Therefore, fraction of total cake shared by each member will be $\frac{1}{6}$ of the total amount of cake.
