Answer:
(b) 2.175 miles to 2.185 miles
Step-by-step explanation:
When a value is rounded, the original "exact" value is presumed to be within 1/2 of the value of one least-significant unit of the rounded number.
<h3>Application</h3>
A rounded value of 2.18 has a least-significant digit with a place value of 0.01 units. Half that value is the "margin of error". That is, the range of numbers that would be rounded to 2.18 is ...
2.18-0.005 ≤ x < 2.18+0.005
2.175 ≤ x < 2.185 . . . . miles

= 1/7 (x + 27)

Ax+3=7-bx
Ax=4-bx
A=4-bx/x
Ax+3=7-bx
Ax-4= -bx
Ax-4/x= -b
-Ax+4/x=b
b= -Ax+4/x
I think it’s 3x
Hope it helps
X=3
g(3)=3+4=7
f(g(3))=f(7)=78
f(g(3))f(g(3))=6084
is this the correct answer?
