A is your answer my friend
18) 54.8 centimeters
19) 0.05 liters
The equation of the line is y=mx+b
so now you can substitute:
3=1/5(-1)+b
3= -1/5+b
now add 1/5 on both sides
3 1/5=b
so the final equation is
y=1/5x+3 1/5
hope this helps!
Lets divide the problem in parts, first for sandwiches she used 3/4 out of 20 ounces of ham:
(3/4)(20) = 60/4 = 15
so for sandwiches Lauren used 15 ounces
Then for omelete she used 1/5, that is:
(1/5)(20) = 20/5 = 4
then Lauren used 4 ounces for omelete
So Lauren used 15 ounces for sandwiches and 4 ounces for omelete, that is 19 ounces in total, so there are left from the 20 original ounces:
20 - 19 = 1
there is 1 ounce of ham left
