Answer:
1,854
Step-by-step explanation:
MULTIPLY FIRST:
5 x 10 = 50
4 x 1 = 4
8 x 16 = 128
6 x 100 = 600
1 x 1000 = 1000
ADD:
50 + 4 + 128 + 600 + 1000 = 1,854
Answer. x>1
Explanation. when “x” is greater than one. We use the greater than symbol and use “x” as the variable.
The area is L * W
9 * 9= 81 in^2

Answer:
Let x = Kilometers by bus
then x + (x + 350) = 1100
2x = 750
x = 375 by bus
x - 350 + x = 1100
2x = 1450
x = 725 by train
i hope this helps a little bit
