hmmm let's find the distance between B and C first off.
hmmm if BC is that much, then AB + AC = 7, since AB + AC + BC = 12 which is the perimeter, Check the picture below.
10.2 is the right answer 10 dollars and 20 cents is more then 10 dollars and 02 cents
Answer:
80 hours
Step-by-step explanation:
let d represent doug, let l represent laura
first, set up a system of equations representing the problem:
since doug spent 10 less than twice the hours laura did, and we know that the total amount of hours they spent together is 230:
l=2d+10
d+l=230
then solve:
*first i rearranged the equations so i can solve this system of equations using elimination method*
l-2d=10
l+d=230
*subtract*
3d=240
d=80
so, doug spent 80 hours in the lab

Is this the question you are trying to ask?
-Alexia set up the tent below in case it rained during the barbecue.Which equation shows how to determine the volume of the tent?-
Bc this doesn't even have a question mark. "Alexia set up the tent below in case it rained during the barbecue." haha
