Answer:a=-8
Step-by-step explanation:
4+7a=12+8a
So first you want to have the variables on the same side
4+7a-7a=12+8a-7a
This is how you got the 7a to the right side. Then you subtract 8a-7a So the equation becomes
4=12+a
Now there are two ways of doing this.
1. 4-12=12-12+a
You moved the 12 to the left side so you have the same variable on one side
4-12=-8
So then a=-8
Or
2. 4-4=12-4+a
0=8+a
then you would have to subtract 8 to keep 'a' by itself
-8=8-8+a
simplify it
-8=a

Answer:
4.33
Step-by-step explanation:
Given data
x1= 3
y1=3
x2=6
y2=16
M= y2-y1/x2-x1
substitute
M=16-3/6-3
M= 13/3
M=4.33
Hence the gradient is 4.33
1.01011 is non repeating
2.23232323 is repeating (the bar on top of the 23)
3.42666666 is repeating ( the bar on top of the 6)
4.321321321 is repeating since 321321321 is repeating with the dots
They are similar because their sides are all the same. Like 4, 4, 4, and 4. Also, 6, 6, 6, and 6.
