3. We can see that 
1+100=101
2+99=101
3+98=101
.................
and so on
From 1 to 100, there are 50 pairs that has the sum is 101
Z=101×50=5050
4. We can see that
1-2=-1
3-4=-1
5-6=-1
...........
and so on
There are 10 pairs that has sum is -1
Z= 10×(-1)=-10

Answer:
x = -3
Step-by-step explanation:
<u><em>⇒ Given:</em></u>
<em>4x + 1 = 2x -5</em>
<em />
<u><em>║ Solve ║:</em></u>
<em>4x + 1 = 2x -5</em>
<em>Subtracting 1 from both sides:</em>
<em>4x + 1 = 2x -5</em>
<em>4x + 1 - 1 = 2x -5 -1</em>
<em>4x = 2x - 6</em>
<em>Now subtracting 2x from both sides:</em>
<em>4x - 2x = 2x - 6 - 2x</em>
<em>2x = -6</em>
<em>Then divide both sides by 2</em>
<em>2x/2 = -6/2</em>
<em>x = -3</em>
<em />
<em>Thus, the answer is x = -3.</em>
<em />
<u><em>xcookiex12</em></u>

Step-by-step explanation:
(t+4)(t+7)-54=0
t²+7t+4t+28-54=0
t²+11t-26=0
(t-2)(t+13)=0
t-2=0
t=2
t+13=0
t=-13
