Answer:
x = 33
y = 41
Step-by-step explanation:
GIven
x: number of nickels
y: number of quarters
A nickel = $0.05
A quarter = $0.25
then we have the system of equations
0.05*x + 0.25*y = 11.90
x + y = 74
Which can be solved applying any of known methods. Then, the solution is
x = 33
y = 41
hope this was helpful.
Answer:
Step-by-step explanation:
Area of the yard is 40 x 25 = 1000
how much area does the fertilizer cover?
In the matrix, the first row is exactly twice the second. This implies that the determinant is zero.
If the matrix system has determinant zero, the system has either no solutions or infinite solutions.
However, just like in the matrix, in the constant vector the first term is twice the second. This means that the system has infinite solutions.
In fact, if you write this system in expanded form, you can see that it generates two equations, the first being twice the second:
you add +50 dollars in ur account then -20
Answer:
C) y -1 = -8
Step-by-step explanation:
The solutions to the various equations are ...
w = -7/-4 = 1.75 . . . . . divide by -4
x = 3/2 = 1.50 . . . . . . .divide by 2
y = -7 . . . . . . . . . . . . . .add 1
z = 5 . . . . . . . . . . . . . . add 1
The value farthest from 0 is y = -7, corresponding to choice C.
