Answer:
11
Step-by-step explanation:
Suitable software can generate these collections. They are ...
{13,1,1,1,1,1}, {11,3,1,1,1,1}, {9,5,1,1,1,1}, {9,3,3,1,1,1},
{7,7,1,1,1,1}, {7,5,3,1,1,1}, {7,3,3,3,1,1}, {5,5,5,1,1,1},
{5,5,3,3,1,1}, {5,3,3,3,3,1}, {3,3,3,3,3,3}}
4 quarters
4 quarters = $1
14 nickels = $0.70
6.6 repeating cm per min
y=-2x+8
y=x-1
Solve y=-2x+8 for y
Substitute -2x+8 for y in y =x-1
-2x+8=x-1
Add -x to both sides
-2x+8+-x=x-1+-x
-3x+8=1
Add -8 to both sides
-3x+8+-8=1+-8
-3x=-9
Divide both sides by -3
-3x/-3=-9/-3
x=3
Substitute 3 for x in y =-2x+8
y=(-2)(3)+8
Simplify both sides of the equation
y=2
Answer : y=2 and x=3
(3,2)
