Asap 7. solve the equations: -3 = z + 4 a. z = 4 b. z = -4 c. z = -7 d. z = 7 z - 4 = -8 a. z= -2 b. z = 32 c. z = -4 d. z = -12 6.4 = 4x a. x = 2.4 b. x = 1.6 c. x = 4 d. x = 10.4 -9 = r/4 a. r = 36 b. r = 13 c. r = 9/4 d. r = -36 -9 = 3/8n a. n = =24 b. n = 24 c. n = 5 d. n = -5

What are the related frequencies to the nearest hundredth of the columns of the two way table? group 1: a-102 b-34group 2: a-18 b-14edited: i don’t have all day to be waiting for an answer. i figured it out.

Anyone know? is appreciated! will mark brainliest if correct!
