Answer:
Step-by-step explanation:
5.67x - 8.16 + 3.6x + 9.2
Write the like terms together
= 5.67x + 3.6x - 8.16 + 9.2
{8.16 & 9.2 have different sign, so subtract and the result will have the bigger numbers sign}
= 9.27x + 1.04
The first vector's speed is 12.57 meters for one second
The second vector's speed is 5.21 meters for one second
The total distance is 12.57+5.21 = 17.78 meters over two seconds
Hence the speed is 17.78 / 2 = 8.89m/s
Easy not to call it 2 ones and just call it 2 instead.
a tenth is 1 divided by 10 = 0.1.
20 tenths therefore is 20 times 0.1 = 2
