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
Answer:
34.93
Step-by-step explanation:
Ok, so using the formula for a trapezoid, you would get that Jim's garden's area is equal to 135.
Since each grass bag can cover 20m of the garden,
135/20=6.75
You would need seven bags because you can't buy 6.75 bags at a store.
Since each bag of grass seed is 4.99, 7*4.99 = 34.93.
I'm doing this in dollars, so I'm assuming that one pound is 100 cents or something like that.

Answer:
Length of rectangle = 16 cm
Width of rectangle = 4 cm
Step-by-step explanation:
Given:
Area of rectangle = 64 cm²
Find:
Length and width
Computation:
Assume;
Length of rectangle = a
So,
Width of rectangle = a -12
Area of rectangle = l x b
So,
a(a-12) = 64
a² - 12a - 64 = 0
a² - (16-4)a - 64 = 0
a² - 16a+ 4a - 64 = 0
a (a-16) + 4(a-16)= 0
(a-16)(a+4) = 0
a= 16 , a = -4
So,
Length of rectangle = 16 cm
Width of rectangle = a -12
Width of rectangle = 16 -12
Width of rectangle = 4 cm
