Answer: -10x + 1y = 2
Step-by-step explanation:
The standard formula says that Ax + By = C where A is the coefficient of the x variable, B is the coefficient of the y variable, and C is the constant value.
y = 10x + 2 Subtract 10x from both sides of the equation .
-10x -10x
-10x + 1y = 2
Answer:
4 3/8
Step-by-step explanation:
1. We can use the formula
<em>Area = L (length) x W (width)</em>
2. The area is unknown so we can substitute it for<em> a</em>
<em> </em>The length and width are both known, so we can plug them in.
<em>a= 2 1/2 x 1 3/4</em>
3. Solve by multiplying
<em>a=4 3/8</em>
Answer:
$480
Step-by-step explanation:
So first, you find how much he paid per hour which would be 80 * 5 = $400. Then, you have to add the tip in so you do $400 * 1.2 (or 120%) = $480.
N=3/13
1) Simplify the right side first. -1/9 = 8/9 - 13n/3
2) Switch the sides so n is on the right (optional): 8/9-13n/3 = -1/9
3) Move all terms not containing n to the right of the equation. Do this by subtracting subtracting. -1/9 - 8/9 = -1
4) Multiply both sides of the equation by 3 to isolate the variable "n".
(3)-13n/3 = -1(3). The new equation is -13n = -1.
5) Divide each term by -13 and simplify. The final answer is n=3/13
