D = 2m - 4 (Dad's age is 4 less than twice Mark's)
m + d = 95 (their ages total 95)

We have a value for d, so plug it in:
m + 2m - 4 = 95
Simplify:
3m - 4 = 95
Add 4 to both sides:
3m = 99
Divide by 3:
m = 33

Answer:

D

Step-by-step explanation:

pogonyaev

The adult weight in pounds is 185.39 lb

<u>Solution:</u>

Given that adult weighs 84.09 kilogram

To find : Adult’s weight in kilograms to pounds

We have the change the weight of the adult from kilogram to pound

The conversion between kilogram and pound is as follows:-

1 kilogram = 2.204623 lb

To find the adult weight in pound, we need to multiply the adult weight in kilogram by 2.204623

<em><u>Converting 84.09 kg to pound:</u></em>

\begin{array}{l}{84.09 \mathrm{kg}=84.09 \times 1 \mathrm{kg}} \\\\ {84.09 .09 \times 2.204623=185.39 \mathrm{lb}}\end{array}
