The length of a room is 3 feet more than twice the width.
10*2=20+3=23
10+10= 20 23+23= 46
46+20=66
10= the width 23= the length.
I hope this helps!

Answer:
Step-by-step explanation:
y ∞ x/m
y = kx/m
Where k is the constant of proportionality
A. k = ym/x
y=5 when x=7 and m=4
k = (5×4)/7
k = 20/7
y = 20x/7m
B)the value of when x=2and m=2
y = 20x/7m
y = (20×2)/(7×2)
y = 40/14
y = 20/7
y = 2 6/7
C. The value of m when y=2 and x=4
y = 20x/7m
7ym = 20x
m = 20x/7y
m = (20×4)/(7×2)
m = 80/14
m = 40/7
m = 5 5/7
Answer:
9.4 miles
Step-by-step explanation:
5 ² +8 ² =C ²
25+64=c ²
89=c ²
c=9.4
I think the answer would be "I spent 4 hours teaching lessons".
