The person above me got that horrible wrong, do not put that.
You also wrote the question wrong, please be more careful when posting.
x-3y=18
Move x to the other side by subtracting it since it’s positive.
-3y = -x + 18
Divide the whole equation by -3 to find the value of just 1 y.
-3y/-3 = -x/-3 + 18/-3
y = 1/3x -6
Length times width so that would be 21
Answer:
1)
At Bombinoes, if he delivers 10 pizzas, he will make $81. y = 2.50x + 56
At Little Squeezers, if he delivers 10 pizzas, he will make $78. y = 3x + 48
At Pizza Tent, if he delivers 10 pizzas, he will make $79.50. y = 2.75x + 52
2)
Little Squeezers would pay him the most if he delivered 20 pizzas. They would pay him a total of $108.
Step-by-step explanation:
The straight line joining the points A(3,-5) and B(6,k) has a gradient of 4.
Gradient is the slope
So the slope of the line joining the points A(3,-5) and B(6,k) is 4
Slope of line joining two points = 
A(3,-5) and B(6,k) are (x1,y1) and (x2,y2)
slope =
slope = 
We know slope =4
Cross multiply and solve for k
k + 5 = 12
k = 7
The value of k = 7
Answer:
7.591 x 10^10
Step-by-step explanation:
You have to move the decimal point over until you have a number under 10 and also the number of times you had to move the decimal point at the end of the number over is your exponent for 10
