Start by converting your two equations into slope-intercept form.
3x - 3y = -9
-3y = -3x -9 Subtract 3x from both sides
y = x +3 Divide both sides by -3
2x + y = 9
y = -2x + 9 Subtract 2x from both sides.
Then graph both lines (in which case the point where they intersect is the solution) or substitute in each point until both equations are true.
In this case the solution is (2,5); both equations become 5=5 when you substitute in the point's coordinates.
We can solve problems like this using multiplication rules. Since the order of colors and combinations does not matter, we can multiply all values in any order we so choose. In this case, our values are colors and vehicles:
Car: Red, Yellow
Truck: Black, White, Silver
Motorcycle: Green, Blue, Orange
We have 2 options with a car, 3 options with a truck, and 3 options with a motorcycle. Since he wants one of each, we will multiply all of the color options together:
2 x 3 x 3
= 18
Edwin has 18 different combination of vehicles to choose from.

Answer:
it is application of the multiplication property of equality
Step-by-step explanation:
You can use "cross products" to solve any proportion. What looks like a "cross product" is just application of the multiplication property of equality. That property says the variable value is unchanged if both sides of the equation are multiplied by the same value.
For your fraction, the "cross product" is what you get when you multiply both sides of the equation by 500.

Note that the next step here is to divide by the x-coefficient, the 5 that was in the left-side denominator.

Please also note that this is exactly the same result you would get by multiplying the original equation by the original denominator of x.
Step-by-step explanation:
staff of 600 is 300 and the form of 1050 is 525
Answer: C
Step-by-step explanation: The numerator is the angle measure, and the denominator is the side length. For angle B, the angle is 47 degrees. The opposite side is b, which is 85. We are finding the angle A, which is the numerator. The side 94 is opposite of angle A.
