The answer would be 36:18 and done
Answer:
5y + 15x = 25, 9x - y = -4
Step-by-step explanation:
The standard form is Ax + By = C. We can make this simple by first creating the slope intercept equations of both questions:
1. y = (-3/5)x + 5
2. y = 9x + 4
For the first one, we must first get rid of the denominator by multiplying everything by 5, so we get 5y = -15x + 25, and then you can add 3x to both sides to arrive at your first standard eqn, 5y + 15x = 25.
For the second, all you need to do is swap the y and the 4, subtracting both y and 4 from each side, arriving at 9x - y = -4
Answer:

Sorry But I cannot explain the working out.
Answer:
<h2><u><em>
x = 9</em></u></h2>
Step-by-step explanation:
2x-10=8
2x = 10 + 8
2x = 18
x = 18 : 2 =
x = 9
-----------------------
check
2 * 9 - 10 = 8 (remember PEMDAS)
18 - 10 = 8
8 = 8
the answer is good
Multiply all the numbers by 2 first, so 12 yards 18 ft 8 in. After that, you simplify. There are three feet in a yard, so in eighteen feet there are 6 yards. That makes 18 yards and 8 in.
