What is the missing term of the arithmetic sequence? 6, ______, 30
Andrei [34K]

Let k = the constant amount added to the sequence since this is an arithmetic sequence

       x = missing number

You have to formulate an equation based on the sequence:

6 + k = x or k = x – 6

x + k = 30

Substitute the value of k to the second formula:

x + x – 6 = 30

2x = 36

x = 18

Therefore, the missing number is 18.

2 1/4 - 2/3. A. 1 3/7. B. 1 7/12. C 2 3/7. D 2 11/12
DedPeter [7]

Answer:

B.) 1\frac{7}{12}

Step-by-step explanation:

2\frac{1}{4} -\frac{2}{3} Then multiply 4 by 2, then add 1.frac{9}{4} - \frac{2}{3} \\

Then find the Least Common Denominator(LCD); simply just multiply 4 by 3 to get 12; then multiply using the opposite number.

\frac{3}{3} *\frac{9}{4} - \frac{4}{4} * \frac{2}{3}

to get: \frac{27}{12} - \frac{8}{12}.

now the denominators is the same on both sides, just subtract the numerator.

27 - 8 = 19

Now simply: \frac{19}{12} = 1\frac{7}{12}.

Your final answer is 1\frac{7}{12}[/tex].

What is the value of x for 7x - 12 y = 180 / 7x = 84
katrin2010 [14]

eq^2: 7x=84 divide 84 by 7 which is 12.

therefore x is equal to 12. Then

1) take that 12 you got in equation 2 and substitute in equation 1 which is:

7x-12y=180

7(12)-12y=180

84 -12y=180

-12y=180-84

-12y=96 ............divide both sides with -12

-y=8 (×-1) both sides

y= -8

therefore 7(12)-12(-8)=180
