Answer:
6 quarters, 3 dimes, and 12 nickles
Step-by-step explanation:
Let's say Q is the number of quarters, D is the number of dimes, and N is the number of nickles.
From the information in the problem, we can write three equations:
25Q + 10D + 5N = 240
N = 2Q
Q = 2D
Solve the system of equations using substitution.
25(2D) + 10D + 5(2Q) = 240
50D + 10D + 10Q = 240
60D + 10(2D) = 240
60D + 20D = 240
80D = 240
D = 3
Q = 6
N = 12
There are 6 quarters, 3 dimes, and 12 nickles.
3 over 7, 2 over 5, 2 over 3 so your answer is b. this is the correct answer I think because1/2 equals one half 2/2 equals 1 whole hope you understand what I meanunderstand what I mean
Factor out a 3x:
3x(x2+4x+6)
Since you can't factor out the quadratic that's as far as it goes:
Answer:
3x(x2+4x+6)
Answer:

Step-by-step explanation:
Given



Required
Find Y
To do this, we make use of the mid-point formula
i.e.

WX and ZY are the diagonals of the parallelogram.
The mid-point of WX is:


The mid-point of ZY is:

Equate both values of M

Multiply both sides by 2

By comparison:








Hence:
