Answer: 
Step-by-step explanation:
Given the equation 
you need to solve for the variable "b".
You need to apply Distributive property on both sides of the equation:
Now you need to add 21 to both sides of the equation:
Subtract 
from both sides:
And finally, you can divide both sides of the equation by 18:
Answer:
y+4 = 2(x+3)
Step-by-step explanation:
We have 2 points so we can find the slope
m = (y2-y1)/ (x2-x1)
= (2--4)/(0--3)
= (2+4)/(0+3)
= 6/3
= 2
We want to use the point slope form of the equation for a line
y-y1 = m(x-x1)
We know the slope =2 and the point (0,2)
y-2 = 2(x-0)
y-2 = 2x
We could also use the other point (-3,-4)
y--4 = 2(x--3)
y+4 = 2(x+3)
Answer: A
Step-by-step explanation: This sign should be shown one-half a mile before the working area, just in case they have to detour to another route.
Answer:
7/16
Step-by-step explanation:
Common denominator of 16
8/16-1/16=7/16
Consider the intergers as, x and x+1
x+(x+1)=31
2x+1=31
2x=30
x=15
So, (x+1)=(15+1)=16 would be larger number.
