Answer:

-3

Step-by-step explanation:

Write the equation down, the first step is to minus the one from both sides of the equal sign(since it’s the opposite then adding) so you cancel out the 1 and do 7-1 your equation would look like this : -2x=6 the next step is to divide the -2 (it’s the opposite of multiplication) your answer would be x=-3

If you notice the terms, they're

7, -21, 63, -189 and so forth.

7*-3 = -21  and -21 * -3 is 63 and so forth, meaning the "common ratio" is -3.

now, for a common ratio say "r", which is a fraction, namely less than ±1 and more than 0, or |r| < 1 ,  you do have a convergent sequence.

however this one notice, |-3| is 3, and that's greater than 1 clearly, therefore is divergent, meaning the summation has no finite value.

3 times a number is 54 less than the square of that number. Find the negative solution.
son4ous [18]

Answer:

-6

Step-by-step explanation:

3n = n² - 54

n² - 3n - 54 = 0

n² - 9n + 6n - 54 = 0

n(n - 9) + 6(n - 9) = 0

(n - 9)(n + 6) = 0

n = 9 , -6

Mrs.gauthier plans to take her class on 2 field trips this year there are 23 students in her class and each field trip will cost
Alina [70]

If there is 2 field trips with 23 students and each student costs $5 dollars. So for the 1st trip it will be 23x$5

1st trip- $115

And on the second trip its the same because there is 23 students that cost 5 dollars so it will be 23x5

2nd trip- $115

To find out the total of both trips youd add 115+115/

In total, for both trips it will cost $230 dollars.
