Answer: 5 units
Step-by-step explanation:
The area of a parallelogram is  . SInce we know the area and the height, we can directly plug the values into this equation and solve for the base.

20=b(4)         [divide both sides by 4]
b=5 units

Answer:
a.  (15, 15)
Step-by-step explanation:
We start with those two equations:
1) a - 1.2b = -3
2) 0.2b + 0.6a = 12
We'll begin by modifying equation #1 to isolate a:
a = -3 + 1.2b
Then we'll use this value for a in the second equation:
0.2b + 0.6 (-3 + 1.2b) = 12
0.2b - 1.8 + 0.72b = 12
0.92b = 13.8
b = 15
Then we'll place that value of b in the first equation to find a:
a - 1.2 (15) = -3
a - 18 = -3
a = 15
 
        
             
        
        
        
The value of seven is in the thousands place and is 10 time the number seven if it were at the hundreds place, which is where 2 is. 
7000=10 x 700
7000=7000
