X=1 because -7 times 1 = -7
Answer:
28/81
Step-by-step explanation:
4/9 x 7/9; 2 negatives = a positive so the answer is 28/81
Hope this helps! :)
There would be 36/12 if you were talking about 3 wholes but if you were just talking about 1/3 you would have 3/12
now for the example I don't know
Question 1. -3 + v5 = 0
Work : -3 + 5v = 0
5v = 3 ( divide )
answer v = 3/5
Question 2. 1 - 7B = -20
work : -7b = -20 - 1
-7b = -21 ( divide )
answer b = 3
question 3 : -k - 5 = 0
work : -k = 5
answer : k = - 5
Question 4 : -1 + 8a = 129
work : 8a = 129 + 1
8a = 130 (divide )
answer a = 65/4
X = 13
using proportional reasoning, 48/12=4, and dividing 52 by 4 will give you the answer, 13.
