Answer:
Question 1: 5
Question 2: 143/5 or 28.6
Answer:
4
Step-by-step explanation:
We want to find the highest common factor
Breaking them into factors
28 = 4*7 = 2*2*7
40 = 4*10 = 2*2*2*5
12 = 4*3 = 2*2*3
24 = 3*8 = 3*2*2*2
The factor that appears in all is 2*2
2*2 =4
W=4x+9y
-9y=-w+4x
9y=w-4x
y=(w-4x)/9
Hope this helps :)
