Write a conjecture that describes the pattern in each sentence -5, 10, -20, 40, -80

1 answer:

3 0

This pattern is multiply by -2. Your conjecture or conclusion will be that it changes by a multiple of negative two each time. Half the numbers are positive because if you multiply two negatives, they equal a positive. Hope this helps.

Answer:

x = $25.8^{o}$ and y = $51.4^{o}$

Step-by-step explanation:

Known that he sum of angles on a straight line is $180^{o}$ . From the diagram;

2y + x + y = $180^{o}$

x + 3y = $180^{o}$ ................ 1

Also,

2x + x + 2y = $180^{o}$

3x + 2y = $180^{o}$ .............. 2

Using the elimination method, multiply equation 1 by 3 and equation 2 by 1

3x + 9y = 540 ............ 3

3x + 2y = $180^{o}$ ............. 4

7y = 360

y = $\frac{360}{7}$

y = $51.4^{o}$

substitute the value of y in equation 1,

x + 3y = $180^{o}$

x + 3(51.4) = $180^{o}$

x + 154.2 = $180^{o}$

x = $180^{o}$ - 154.2

x = $25.8^{o}$

Thus, x = $25.8^{o}$ and y = $51.4^{o}$

i’m having some trouble with these three questions it would be a big help if someone could help me out :)

algol [13]

I’m not sure if I’m right but I think u have to add the 3 largest numbers in the population section and then add the other 3 least numbers in the same section and then u have to subtract those 2 answers.

I’m really bad at explaining but I hope u get it
