Answer:
<h2>A. x = 1</h2>
Step-by-step explanation:

A= 4 tenth 2 hundredth 3 thousandth
b= 3 tenth 2 hundredth 6 thousandth 7 ten thousandth 8 hundred thousandth
c= 4 tenth 5 hundredth 2 thousandth 4 ten thousandth
d= 3 tenth 0 hundredth 0 thousandth 6 ten thousandth
Well you take the length of each section, which is "blank" rn, and multiply into 8? I don't know what will the meaning of "at most" be effective here, but if it's normal calculations, x = "blank" x 8
40+60=100
I hope this helps^^
