I have to write the linear process... of all of them.
1 answer:
15−2x−8−3x=−x−12+4x+43
now combine all the like terms on each side.
Add -2x and -3x
subtract 15 and -8....you subtract because the sign are different
now do the same for the other side
−5x+7=−x−12+4x+43
−5x+7=3x+31
bring the x value from the right side to the left side.
−5x+7−3x=31
combine like terms on left side
−8x+7=31
now move +7 to the right side which become..
−8x=−7+31
−8x=24
we will need to single out X by dividing
answer: X= -3

The distance between two points is the number of units between them.
<u>Halfway points (a) and (b)</u>
To locate a point halfway points (a) and (b), we use the following steps
- Calculate the absolute difference between both points
- Divide the absolute difference by 2
- Add the quotient to the smaller point.
Assume the smaller value is (a), the point (P) halfway points (a) and (b) would be
Take for instance, a = 5, and b = 10.
The halfway point would be:
The halfway point between 5 and 10 is 7.5
The formula works for negative values, and absolute values are used to return the actual difference between both points
<u>Real world circumstance</u>
The formula can be used to calculate the halfway distance between a school gate and the school library (as an instance)
<u>Fractional distance</u>
To determine the fractional distance, we simply replace the 1/2 in the original formula with the appropriate fraction.
Take for instance, three-fourths from (a) to (b) would be:
