Since the midpoint lies on the axis, both ends are therefore equidistant from the axis and are mirrors of each other so..
Q = (4,9)
Let dimes = d and quarters =q
D + q = 50
D= 50-q
0.10d + 0.25Q = 7.70
Replace d with 50-q:
0.10(50-q) + 0.25q = 7.70
Simplify:
5 -0.10q + 0.25q = 7.70
5 + 0.15q = 7.70
Subtract 5 from both sides:
0.15q = 2.70
Divide both sides by 0.15:
Q = 2.70 / 0.15
Q = 18
D = 50-18 = 32
There are 32 dimes and 18 quarters
Answer:
= 4
Step-by-step explanation:
first lets find the value of x in 3x+2=5/9
3x+2=5/9
3x = 
-2
3x = 
3x = 
x = 
x = 
can also be written as 
−3x+8
-3 () +8
+8
= 4
-4 + -10 = -14
Negative 4 plus negative 10 = negative 14 (thats what I think the answers gonna be, but im not that sure though)
you can answer it six point six six six six six infinity or you can answer it 6.7 depending upon how they want
