I don't know which quadratic equations you have learned. you can choose the quadratic formula: x= -b +- square root of D divided by 2 times a. There is also factoring or solving by undoing.
2/6 is also equal to 1/3. so if you multiply 69 by (1/3) it equals 23. giving you 23 kit kats.
x= 4. 225 is 15 times bigger than 15. so if you divide 60 by 15 it gives you your answer of 4.
Answer:
x = -9
Step-by-step explanation:
Distribute the -7 to (x + 9) and distribute 9 to (x - 5), creating the equation, -7x - 63 = 9x - 45 -14x. Then you add the like terms, 9x - 14x, which equals -5x. So the equation is now -7x - 63 = -5x -45. Add the -5 to both sides which makes -2x -63 = -45. Then add the -63 to both sides, which equals 18, then divide that by -2 and you get -9 as your answer.
Answer:
time taken=1800 seconds
Step-by-step explanation:
velocity=v=10m/s
distance=S=18km=18×10³m=18000m
t=?
as we know that
velocity=![\frac{distance covered}{time taken}](https://tex.z-dn.net/?f=%5Cfrac%7Bdistance%20covered%7D%7Btime%20taken%7D)
velocity×time taken=distance covered
now here we have to find time
time taken=![\frac{distance covered}{velocity}](https://tex.z-dn.net/?f=%5Cfrac%7Bdistance%20covered%7D%7Bvelocity%7D)
time taken=![\frac{18000m}{10m/s}](https://tex.z-dn.net/?f=%5Cfrac%7B18000m%7D%7B10m%2Fs%7D)
time taken=1800seconds
