3, 552, 308, 725 in word form is:
Three billion, five hundred fifty-two million, three hundred eight thousand, seven hundred twenty-five.
Using a system of linear equations, the distance between points A and B is 6000 cm
Time taken = Distance / speed
Let ; distance = d
<u>To</u><u> </u><u>time</u><u> </u><u>:</u><u> </u>
- <u>t</u> = d / 4
- <em>4t = d ______(1)</em>
<u>Fro</u><u> </u><u>time</u><u> </u><u>:</u><u> </u>
(t + 15 × 60) = d / 2.5
2.5(t + 900) = d
<em>2.5t + </em><em>2250</em><em> = d ______(2)</em>
Equate (1) and (2)
4t = 2.5t + 2250
4t - 2.5t = 2250
1.5t = 2250
t = 1500 seconds
From (1) :
d = 4t
d = 4(1500)
d = 6000 cm
Therefore, the distance from point A to B is 6000 cm

60 / 5 = 12 miles per gallon
36 miles = 12 miles / gal * x gallons
divide by 12
36/12 =x gallons
3 =x
He needs 3 gallons
Answer:
2x⁴y²
Step-by-step explanation:
The question gives us the expression;
12x⁷y³ ÷ 6x³y
We are supposed to simplify the expression;
First we could divide the digits;
12 ÷ 6 = 2
Then we divide the like terms;
x⁷ ÷ x³
This means;
y³ ÷ y
That is;
Therefore, the simplified expression will be 2x⁴y²
