Answer:
x ≥ $90 per kid
Step-by-step explanation:
2800 - 1000 = 1800
1800 ÷ 20 =90
In order to meet their goal of 2800, each kid must make at least 90 dollars
Here, I’ve answered this question before:
Standard form is Ax + By = C where A and B are coefficients to x and y respectively
So we have to move y to the right side and 3 to the left side, because 3 is the constant in this case, and therefore the C of our equation.
Since the sign changes after moving them over the equation, y and 3 will both be negative
-3 = 1x - y
So let's get k on one side:
2k = 2
Divide by 2:
k = 1
If you want to check your work:
1 + 1 = 3 - 1
2 = 2
B)
0
Positive 17 Plus Negative 17=0
