What are the next two numbers in this pattern?

1 answer:

3 0

The answer is A. 243, -729

The pattern of this is that they multiply each number by -3.

3*-3=-9
-9*-3=26
27*-3=-81

So you have to multiply -81 by -3. Then multiply that by -3 to get the second number

-81*-3=243
243*-3=-729

PLS HELP With GEO FOR 50 PTS!!!!!

zaharov [31]

Without doing the math, you can can see that the 100ft marker is about 1/3rd of the bottom(combining the triangle and the rectangle) This floor is practically(if not exactly) the same length of each vertical side of the building.

"100 x 3" is 300, So I am pretty sure the answer is 308.

Good luck!

HELP PLEASE Sam and George both worked hard over the summer. Together they earned a total of $525. George earned $75 more than S

ZanzabumX [31]

Answer: Sam = $225 George = $300

Step-by-step explanation:

NOTES:

Sam: s

George: g = s + 75

Together: s + g = 525

The two equations that can be created are "George" and Together"

The system is: $\left \{ {{\text{g = s + 75}} \atop {\text{s + g = 525}}} \right.$

see attached graph

The intersection of the two lines is at (225, 300). Since Sam represented the x-axis and Georege represented the y-axis, then Sam = $225 and George = $300.

BONUS:

This system can also be solved algebraically using the substitution method.

Replace "g" with "s + 75" into the second equation:

s + (s + 75) = 525

2s + 75 = 525

2s = 450

s = 225

Next, input the s-value into the George equation to solve for g:

g = s + 75 = (225) + 75 = 300
