Which equation models this situation? The sum of 23 and a number is 39.
O A. 23 + x = 39
B. 23 - x = 39
C. 39 + x = 23
O D. 23+ 39 = x

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

the correct answer is c
