Answer:
Step-by-step explanation:
Question 1
System of equations is,
y = -6x -------(1)
y = -4x - 2 ---------(2)
Substitute the value of y from equation (1) to equation (2)
-6x = -4x - 2
-6x + 4x = -2
-2x = -2
x = 1
From equation (1)
y = -6(1)
y = -6
Question (2)
System of equations is,
-y = x --------(1)
3x + 5y = 20 ---------(2)
Substitute the value of x from equation (1) to equation (2)
3(-y) + 5y = 20
-3y + 5y = 20
2y = 20
y = 10
From equation (1)
-y = x
x = -10
Question (3)
System of the equations is,
y = -2x - 7 --------(1)
9x - 10y = 12 ----------(2)
Substitute the value of y from equation (1) to equation (2)
9x - 10(-2x - 7) = 12
9x + 20x + 70 = 12
29x = 12 - 70
29x = -58
x = -2
From equation (1)
y = -2(-2) - 7
y = 4 - 7
y = -3
Answer:
1694
Step-by-step explanation:
The $43,329 in this question is just to trick you, so don't worry about this number.
We know her parents have already payed $9,966 for this years taxes.
But they need to pay a total of $11,660 for the year.
11,660 - 9966
=1694
Answer:
32:12
8:3
Step-by-step explanation:
If you multiply both sides of 16:6 you'll get 32:12
If you divide both side of 16:6 by 2 you'll get 8:3
The same thing needs to be done to both sides to make the ratio equivalent
Answer:
T(r) = (16 ties/racks)r
Step-by-step explanation:
Total number of ties = (16 ties/rack)(number of racks), or
T(r) = (16 ties/racks)r
