Answer:
64.5
Step-by-step explanation:
43multiply by 6=258 ➗ by 4n
n= 64.5
Answer:
38.5
Step-by-step explanation:
Use the trapezoid area formula which is (a+b)h/2. We know that a=6, b=8 and h=5.5. Plugging it it to the formula, we get (6+8)*5.5/2 which is 38.5.

Answer:
P(1 dime then 1 nickel)= 15/208= 0.072115
or 7.2%
Step-by-step explanation:
No coin replenished.
total coins =65
P(1 dime then 1 nickel) = (20/65) * (15/64) =20 * 3 / (13 * 64) = 15/(13*16)
P(1 dime then 1 nickel)= 15/208= 0.072115
or 7.2%
Answer:
A. y - x = -4
Step-by-step explanation:
y=x-4
To get infinite equations, the equation must be equal to y=x-4
We will solve each of these for y to see if they are identical
A. y - x = -4
Add x to each side
y-x+x = x-4
y = x-4
This is the same
It will give infinite solutions
B. y - x = -2
y-x+x = x-2
y =x-2
This is not the same.
It is parallel and will give no solutions
C. y - 4 = x
y-4+4 = x+4
y = x+4
This is parallel and will give no solutions
D. y + 4x = 1
y +4x-4x = -4x+1
This will intersect at a point
