I believe that Noah’s number 15.
19 - 15 = 4
4 * 4 = 16
Answer:
36
Step-by-step explanation:
Given that Kelsay opened a bag of marbles.
The bag included 4 colours of marbles of equal numbers.
The four colours are red, yellow, green and blue.
To find the no of marbles of each colour in the bag:
Total number of marbles = 144
Total colours = 4
Hence divide total number by no of colours to get the answre
No of each colour marbles = 144/4 = 36
slope = m = (y2 - y1)/(x2 - x1)
(y2 - y1)/(x2 - x1) = m
(-1 - 1)/(-1 - x) = 2/7
-2/(-1 - x) = 2/7
2/(x + 1) = 2/7
1/(x + 1) = 1/7
x + 1 = 7
x = 6
Answer: x = 6
