Answer:
60 km/hr
Step-by-step explanation:
100+100
_______ =3x
8
3x= 200/8
x=200/24 mps
=30mph
final speed is 60km/hr because its 2x's more =2*30=60
Answer:
- 4099 yes
- 4110 no
- 5909 no
- 5011 yes
Step-by-step explanation:
The digits will be related by a factor of 10 if they are the same digit. 4099 and 5011 have the same digit in the tens and ones places. 4110 and 5909 do not.
The equation of a straight line in "standard form" resembles Ax + By + C = 0.
Starting with y − 3 = 1/3(x − 6) (which is the equation of a line in point-slope form), remove the fractional coefficient 1/3 by multiplying both sides of this equation by 3:
3y - 9 = x - 6.
We want all terms except for 0 to appear on one side of this equation. Subtract 3y from both sides, obtaining:
-9 = 1x - 3y - 6
Finally, add 9 to both sides, obtaining:
0 = 1x - 3y + 3
This result has the form Ax + By + C = 0, and is thus in standard form.
The first digit could be 9 7 5 or 1
The 2nd digit could be 9 7 5 or 1
The third digit could be 9 7 5 or 1
The fourth digit could be 9 7 5 or 1
4 possibilities * 4 * 4 *4= 256 possibilities
