Notice how 1/2 and 3/8 are positive numbers. We add two positive numbers meaning that the result should be larger. However 2/5 = 0.4 is not larger than 1/2 = 0.5

So something went wrong with the adding. It turns out that the error is when the person added the numbers in the denominators (2 and 8 to get 10). This is not allowed. The denominators must be the same and stay the same in order for the fractions to be added.

For example: 1/7 + 2/7 = (1+2)/7 = 3/7
The 7s in the denominator do not change

Therefore the answer is choice B) Not true because 2/5 < 1/2

Is the function tan t positive or negative in Quadrant IV?
AnnZ [28]
If you draw the circle and divide into 4 quadrants, you can see that the sine is negative, since the quadrant is situated in the negative part of YY', and that the cosine is positive, since the quadrant is situated in the positive part of XX'.
And tan =  \frac{sin}{cos} , and negative divided by positive gives a negative answer, which means that the tangent is negative on the quadrant IV.
Hope this helps :)

In the equation 0.75 - 5/8s = 44, how do your combine the like terms?
Mnenie [13.5K]

Answer:

and let's then do away with the denominators, by multiplying both sides by the LCD of all fractions, in this case, the LCD will be 8, and then we'll combine the like-terms, but anyway, let's proceed.
