Answer:
18% decrease
Step-by-step explanation:
- 7,500 - 6,125 = $1,375
- Set up a proportion:   
- Cross multiply, then divide: 1375 × 100 = 137500, 137500 ÷ 7500 = 18 1/3
- 18 1/3% rounded = 18%
- It went down, so it is a decrease
I hope this helps!

Multiply top equation by -2, then add equations so b drops out....solve for a...plug in a to get b
        
                    
             
        
        
        
Regular polygon can be incribed in a circle of radius equal to its side.
so if you join all the vertices to the centre, you will get 6 equilateral triangles. each interior angle will have 2 angles of 60 each. thus interior angle = 120
exterior angle=180-120=60
        
             
        
        
        
Answer:
m<GFA = 110
Step-by-step explanation:
1. ABCD - parallelogram                          Definition of a parallelogram
                                                                    (AB ll CD) (AD ll BC)
2. m<B + m<C = 180                                    Consectuive angles in a 
    110 + m<C = 180                                       parallelogram are supplementary 
     m<C = 70                                     
3. m<GCB = 1/2 m<C                                  Definition of angles bisector
    m<GCB = 70
4. m<B = m<D = 110                                    Opposite angles in a 
                                                                     parrallelogram are congruent
5. m<CDG = 1/2 m<D                                 Defintion of an angle bisector
   m<CDG = 55
6. m<GCB+m<CDG+m<CGD=180              Sum of anlges in a triangle (ΔCDG)
   70 + 55 + m<CGD = 180
    125 + m<CGD = 180
    m<CGD = 55
7. m<CGD + m<DGF = 180                            Linear pair, supplmentary angles
   55 + m<DGF = 180
   m<DGF = 125
8. m<C = m<A = 70                                     Opposite angles in a paralellogram 
                                                                      are congruent
9. m<ADG = 1/2m<D                                       Definiton of an angle bisector
   m<ADG = 55 
10.m<ADG+m<DFG+m<GFA+m<A=360        Sum of angles in quadrilateral 
    55 + 125 + m<GFA + 70 = 360                    DGFA
     m<GFA + 250 = 360
    m<GFA = 110
