Answer:
Step-by-step explanation:
1) 1 km = 1000 m
7.8 km = 7.8 * 1000
= 7800 m
2) 1 g = 1000 mg
1.6 g = 1.6 * 1000
= 1600 mg
2 * 4 = 8
8 < 11 is true
2 * 5 = 10
10 < 11 is true
2 * 5.3 = 10.6
10.6 < 11 is true
2 * 5.7 = 11.4
11.4 < 11 is NOT true.
x = 5.7 is not a solution.
The area of the rectangle is length times width, that is
A = L*W
The problem requires the width so
W = A/L
Given that A = 437 sq. cm and L = 19 cm, therefore
W = 437/19 = 23 cm
That is the answer.
