Hey!
454 rounded to the nearest ten is: 450
This is because 4 is less than five, which is why we would round it to 50.
9.8 pounds in ounces is 156.8
Hope this helped!!
Answer:

Step-by-step explanation:
Subtract 2x from both sides then you’d have -7x+4=16 Then you subtract 4 from both sides and you’d get -7x=12. Next you divide both side by -7 so x=1.75 rounded to the nearest hundredth.
A = 180
b = 180
c = 180
180+180-180 = 180
