Hello !
Okay so what you do is add 10 to the other side
2k - 10 +10 = 6 + 10
You would get ....
2k = 16
Next you divide 16 by 2 which is 8
and that means 8 is equal to k
K = 8
Answer:
Oh easy here is the answer m=21
the answer is there is only 1 solution
Answer:
a). L=53+3 D.... equation
b). Total length of the road after the crew has worked 31 days=146 miles
Step-by-step explanation:
Step 1
Find an expression for calculating the total length of a the road as follows;
L=F+(M×D)
where;
L=total length of the road in miles
F=starting length of the road in miles
M=number of miles per day added
D=number of days the crew has worked
In our case;
L=unknown
F=53 miles
M=3 miles per day
D=unknown
L=53+(3×D)
L=53+3 D.... equation
Solve for L when D=31 days
L=53+(3×31)
L=53+93=146
Total length of the road after the crew has worked 31 days=146 miles
