The two equations given in the question are
y = - 3x
And
y = 6x - 9
Let us now substitute the value of y from the first equation to the second equation, we get
y = 6x - 9
- 3x = 6x - 9
-3x - 6x = - 9
- 9x = - 9
Multiplying both sides of the equation by -1 we get
9x = 9
x = 9/9
= 1
Now let us put the value of x in the first equation, we get
y = - 3x
= - (3 * 1)
= - 3
Number of parts of the drinks = 31+1 = 6
In a 30 quart mixture:-
amount of orange juice = 3/6 + 30 = 15 qrts
.... ... ... pineapple = 2/6 * 30 = 10 qrts
.... ......... ginger ale = 1/6 * 30 = 5 qrts
Answer:
6 inches
Step-by-step explanation:
The perimeter of a triangle is a + b + c
Where, a, b, c are the length of the 3 sides of the triangle ;
Using the ruler ;
a = 1.5
b = 2
c = 2.5
Therefore,
a + b + c
1.5 + 2 + 2.5
= 6 in
