Check explanation
Step-by-step explanation:
Here, we want to make a prove;
Mathematically , since D is the midpoint of CE
Then;
CE = CD + DE
Also, since D splits the line segment into two equal parts as the midpoint, then CD must be equal to DE
I.e CD = DE
Hence, we can express CE as follows;
CE = DE + DE
CE = 2 DE
Divide both sides by 2
CE/2 = DE
Hence; DE = 1/2 CE
Answer:
Step-by-step explanation:
It is 6 units because you find the absolute value of the two different coordinates, in this case it is 4 and -2. Since they belong in different quadrants (one x or y value is positive and the other is negative) you add them. If they are both in the same quadrant, you subtract them.
Should be letter C to question
Let the score in the first game be m and in the second be n.
we know that the total score is 35
this means that: m+n=35 .....> equation I
she scored in the second games 6 times as many as in the first one
this means that: n=6m .......> equation II
substitute with equation II in I:
m+6m=35
7m=35
m=5
therefore,
she scored 5 in the first game and 30 in the second one
this means that she scored 30-5=25 points in the second game more than in the first one
