Answer: The ordered pair is (2,3)
Step-by-step explanation:
To solve this problem, we can use substitution. With substitution, we substitute the y in each problem with the equations. In this case, x + 1 can substitute the y in y = -x + 5. Here is what the problem looks like now:
x + 1 = -x + 5
The reason we used substitution is because we assume that these linear equations are equal. We must prove it, though. We can use algebra.
Move the variables to one side and the numerical values to another:
x + x = 5 - 1.
Simplify.
2x = 4
Simplify.
x = 2.
Now, we got our x value, we can substitute it into our problem:
y = 2 + 1
y + -2 + 5
2 + 1 = - 2 + 5 = 3
Our x is 2, and our y is 3. The ordered pair that is a solution is (2,3).
We start by splitting the shape into two rectangles as shown in the diagram below:
Area of shape A = 10' × 3' = 30'
Area of shape B = 6' × 2' = 12'
Total area = 30' + 12' = 42'

Answer:
Parrot fish = 56
Tigerfish = 224
Step-by-step explanation:
4p + p = 280
5p = 280
p = 56
t = 4 (56) = 224
