11x = 44
X=4
44 + 7 = 51
5x = 20
31 + 20 =51
51 = 51
A) in 4 hours he can go 4*2 = 8 miles
and circular area = pie * R^2 = 3.14 * 8 * 8 =200.96 = 201 square miles
in 5 hours , area = pie* 10*10 = 3.14 * 100 = 314 sq mile.
additional area = 314 -201 = 113
hope it helped
.63-(-9.85)= 10.48 I hope this helped. :)
Answer:
(X, y) =(3,-3)
Step-by-step explanation:
