Answer:
Step-by-step explanation:
We will use mid point formula:
According to the attached picture:
F is the mid point of A and B.
Thus by using formula we have,
F = (2+10)/2 , (4+6)/2
= 12/2 , 10,2
= 6,5
F should be (6,5)
Like wise the matched coordinates are:
D is the midpoint of A and F and is (4,4.5)
C is the midpoint of A and D and is (3,4.25)
E is the mid point of D and F and is (5,4.75)
H is the midpoint of F and B and is (8,5.5)
G is the midpoint of F and H and is (7, 5.25)
I is the midpoint of H and B and is (9,5.75) ..
Answer:
Seth has 21 nickels
Step-by-step explanation:
Let n represent the number of nickels. Since Seth has 8 more nickels than dimes, then (n-8) is the number dimes.
Nickel is worth 5 cents and dime is worth 10 cents. Thus, n nickels are worth 5n cents and (n-8) dimes are worth 10(n-8) cents. The total value of Seth's coins is $2.35 that is 235 cents, then
Solve this equation:
