Answer:
the answer is 1/5
Step-by-step explanation:
The answer is (6, 7)
This is the system of two equations:
<span>2y − x = 8
y − 2x = −5
_____
Express the second equation in the term of y:
2y - x = 8
y = 2x - 5
_____
Substitute y in the first equation:
2(2x - 5) - x = 8
4x - 10 - x = 8
4x - x = 10 + 8
3x = 18
x = 18/3
x = 6
Since x = 6 and y = 2x - 5, then:
y = 2 * 6 - 5
y = 12 - 5
y = 7
Therefore, (x, y) = (6, 7)</span>
660sec in 3 days.
So 220sec per days
220•5= 1100
1100sec = 18min and 30 second.
Ans:
18min and 30 sec
Multiply by the opposite sign the denominator. In the denominator we have the difference of squares.
For it to be in scientific notation, there needs to be a decimal. 492 x 10^5 would need to be changed to 4.92 x 10^5 for it to be considered scientific notation. Whole numbers are void.
