Okay, so -
We have one very important thing here. This little part <em>6 - (-3). </em>
Now, it's essential to remember that when we have two negatives like this, we simply draw a line straight down. It becomes a positive!
So, our question is essentially <em>5 + 6 + 3 - 8 + 4 - 3 = ?</em> instead of <em>5 + 6 - (-3) - 8 + 4 - 3!</em> =)
With that in mind, we simply solve left to right.
<em>11 + 3 - 8 + 4 - 3 = ?</em>
<em>14 - 8 + 4 - 3 = ?</em>
<em>6 + 4 - 3 = ?</em>
<em>10 - 3 = ?</em>
<em>7</em> is our final answer! =)
Answer:
3600(seconds) can also be expressed as 1(kilometer/hour) = 5/18 (meters/second), which is its simplified form. To convert km/h to m/s, directly multiply the given value of speed by the fraction 5/18.
Step-by-step explanation:
I think that explanation is obvious
Answer:
Let's assume the number be 100.
According to the problem , 100 is increased by 100%.
So, new number will be 100+100=200
Now 200 will decreased by 20%.
So, 20% of 200= 0.20*200= 40.
So, again the number has been changed into 200+40=240.
So, x=240
Step-by-step explanation:
Answer = 8
Because:
c(c + 3) - c(c-4) = 9c - 16
c^2 + 3c - c^2 + 4c = 9c - 16
3c + 4c = 9c - 16
7c = 9c - 16
7c + 16 = 9c
16 = 2c
8 = c
