Answer: 2.4×10^5
Step-by-step explanation:
30×8×10^3
First multiply and forget about ×10^3 for now:
30×8 = 240
Then add back the ×10^3:
240×10^3
Then simplify:
2.4×10^5
To check the answer:
30×8×10³=
30×8000= 240000
Then simplify:
240000 = 2.4 ×10⁵
Answer:
Length = 7 Width = 2
Step-by-step explanation:
L = Length
W = Width
L=9w-11
2L+2W=18
2(9W-11) + 2W = 18
18W - 22 +2W = 18
20W -22 = 18
20W = 40
W = 2
L = 9(2)-11
L=18-11
L=7
Answer:
25.50
Step-by-step explanation:
-5 notebooks $2 each
-4 pencils $1.50 each
-2 packs of markers $3.75 each
5(2)+4(1.50)+2(3.75)
$23.5
23.5 times 8.5/100
1.9975
plus 23.5
25.4975
rounded to 25.50
