Which equation has a solution of 4? Select all that apply. A 12x = 3 C10 + x = 14 B 6x = 24 DX-4 = 8​

Answers

Answer:

C and B

Step-by-step explanation:

A. 12x = 3, x =1/4

C. 10 + x = 14, x = 4

B. 6x = 24, x =4

D. x -4 = 8, x =12

Only the expression mentioned in B and C gives the solution as 4. Options B and C are correct.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
A
12x = 3

Simplifying the above expression,
12x = 3
x = 3 / 12
x = 1 / 4

Similarly simplifying all the expressions gives,

what is the 37th term of the arithmetic sequence with the first term -39 and the common difference of 8

257
241
227
249

Answers

Answer:

249

Step-by-step explanation:

The explicit formula for an arithmetic sequence is

an = a1+d(n-1)

a1 is the first term so a1 = -39

d is the common difference so d = 8

n is the term number so n = 37

a37 = -39+8(37-1)

       = -39+8(36)

        = -39+288

        =249
