First, simplify each one.

9.98 x 10^6 = 9980000

7.3 x 10^7 = 73000000

Next, subtract the freight from the aircraft

73000000 - 9980000 = 63020000

Round the decimal point to the first significant digit, and place the amount of place values the decimal point moved to the left as a power sign, over 10.

63020000 = 6.302 x 10^7

6.302 x 10^7 is your answer

hope this helps

Good morning☕️

______

Answer:

w is the width

L is the length

p is the perimeter

w=9

L=27

___________________

Step-by-step explanation:

p=2[(L-4) + (w+1)]

⇔p=2[(3w-4) + (w+1)]

⇔p=2[4w-3]

⇔p=8w-6

⇔66=8w-6

⇔8w=72

⇔w=9

Then L=3w=27

Which of the following is a solution of y - x &lt; -3?<br><br> (6, 2)<br> (2, 6)<br> (2, -1)
Snowcat [4.5K]
Personally I'd solve this inequality for y first:  y < x-3.

That immediately eliminates (6,2) and (2,6).

Starting from y < x-3 and letting 2 sub for x and -1 sub for y, is the following true or false?

-1 < 2 -3     NO.  -1 < -1 is false.  Was there a fourth answer choice?
