Answer:

-23

Step-by-step explanation: You have to combine like terms first:

-3.8x -5.9x                 =223.1

-9.7x                          = 223.1

Then divide om each side of the equation by -9.7.

-9.7x/-9.7                   = 223.1/-9.7

x                               =- 23

Answer:

x=-23

Step-by-step explanation:

-<u>3.8x</u>-<u>5.9x</u>=223.1

Collect like terms by calculating the sum or difference of their coefficients

(-3.8-5.9)x

calculate the difference

-<u>9.7x</u>=223.1

Divide both sides of the equation by -9.7

-9.7x÷(<u>-9.7</u>)=223.1÷(<u>-9.7</u>)

Any expression divided by itself equals 1

x=223.1÷(-9.7)

x=-23

For every integer k from 1 to 10, inclusive the "k"th term of a certain sequence is given by (−1)(k+1)∗(12k). If T is the sum of
Katena32 [7]

Answer:

Option D. is the correct option.

Step-by-step explanation:

In this question expression that represents the kth term of a certain sequence is not written properly.

The expression is (-1)^{k+1}(\frac{1}{2^{k}}).

We have to find the sum of first 10 terms of the infinite sequence represented by the expression given as (-1)^{k+1}(\frac{1}{2^{k}}).

where k is from 1 to 10.

By the given expression sequence will be \frac{1}{2},\frac{(-1)}{4},\frac{1}{8}.......

In this sequence first term "a" = \frac{1}{2}

and common ratio in each successive term to the previous term is 'r' = \frac{\frac{(-1)}{4}}{\frac{1}{2} }

r = -\frac{1}{2}

Since the sequence is infinite and the formula to calculate the sum is represented by

S=\frac{a}{1-r} [Here r is less than 1]

S=\frac{\frac{1}{2} }{1+\frac{1}{2}}

S=\frac{\frac{1}{2}}{\frac{3}{2} }

S = \frac{1}{3}

Now we are sure that the sum of infinite terms is \frac{1}{3}.

Therefore, sum of 10 terms will not exceed \frac{1}{3}

Now sum of first two terms = \frac{1}{2}-\frac{1}{4}=\frac{1}{4}

Now we are sure that sum of first 10 terms lie between \frac{1}{4} and \frac{1}{3}

Since \frac{1}{2}>\frac{1}{3}

Therefore, Sum of first 10 terms will lie between \frac{1}{4} and \frac{1}{2}.

Option D will be the answer.

Solve, 3y(4y−1)−2y(6y−5)=9y−8(3+y)
igomit [66]

Answer:

3y(4y-1)-2y(6y-5)=9y-8(3+y)

12y∧2-3y-12y∧2+10y=9y-24-8y

12y∧2-12y∧2-3y+10y=9y-8y-24

7y=y-24

7y-y=-24

6y=-24

y=-24/6=-4
