Answer:
Increasing a number by 5% and then by 20% is the same as increasing the original number by 26%.
Step-by-step explanation:
Take a number, x.
Now increase it by 5%.
1.05x
Now increase it by 20%.
1.2 * 1.05x = 1.26x
1.26x = 126% of x = 100% of x + 26% of x
100% of x is the same as x, so it is the same as the original x.
The increase is 26% of the original number.
Increasing a number by 5% and then by 20% is the same as increasing the original number by 26%.
Answer:
Step-by-step explanation:
2n³ + 4n² - 7 + ( -n³ -8n -2) =2n³ + 4n² - 7 - n³ -8n -2
=2n³ - n³ + 4n² <u>- 7 -2</u> - 8n
= n³ + 4n² - 8n<u> - 9</u>
3*3=9 it is the same thing as saying g 3 times 3 = 9
Answer: 5 valid arrangements
Step-by-step explanation:
This depends on whether the boys or girls swapping places are considered unique solutions. I'm going to assume that is no, because there would be an unrealistic amount of solutions if it is true.
Assuming G = girl and B = boy, these are the possible arrangements.
(I will bold the valid solutions).
GGBBBB
GBGBBB
GBBGBB
GBBBGB
GBBBBG
BGGBBB
BGBGBB
BGBBGB
BGBBBG
BBGGBB
BBGBBG

BBBBGG
Thus, there are 5 valid arrangements.
Hope it helps <3
