Step-by-step explanation:
<u>A to B</u>
- Avg. speed = Distance covered / Time taken
- Avg. speed = 200 m / 10 s
- Avg. speed = <u>20 m/s</u>
<u></u>
<u>C to D</u>
- Avg. speed = Distance covered / Time taken
- Avg. speed = (500 - 200) m / (60 - 30) s
- Avg. speed = 300 m / 30 s
- Avg. speed = <u>10 m/s</u>
Answer:
1 : 10
Step-by-step explanation:
Equation is 25x + 100 is greater than or equal to 700. First subtract 100 from 700. Then divide 600 by 25 = 24. Sharon must Sell greater than or equal to 24 items
It is true because
when you separate 2y^2 +9y -18, you are supposed to get the factors
(2y-3)(y+6), when you multiply this it gives you the first equation, we know
this because when we multiply the first term it gives us exactly 2y^2 and if we
multiply the last ones it gives you -18, now here is the tricky part, when we
multiply the middle part we get 12y and -3y, when we add these up we get 9y,
now is that the same middle as in the equation? Yes… then our factors are correct
making this true
Hope this helps
