Answer:
The answer is A.
Step-by-step explanation:
It is A because both sides match up except for the last pair, where they are the same. Hope this helped!
Given the system of equations:

To solve it by substitution, follow the steps below.
Step 1: Solve one linear equation for x in terms of y.
Let's choose the second equation. To solve it for x, add 3y to each side of the equations.

Step 2: Substitute the expression found for x in the first equation.

Step 3: Isolate y in the equation found in step 2.
To do it, first, add 48 to both sides.

Then, divide both sides by 15.

Step 4: Substitute y by 5 in the relation found in step 1 to find x.

Answer:
x = -9
y = 5
or (-9, 5)
Also, you can graph the lines by choosing two points from each equation, according to the picture below.
Answer:
$6.42
Step-by-step explanation:
It's very simple, all you have to do is subtract 13.58 by the 20.00$, so you will get that.

Step-by-step explanation:
Answer:
<u>If Caeli will use all of the fabric she has, the base of the flag should be of 4 feet.</u>
Step-by-step explanation:
1. Let's review the information provided to answer the question correctly:
Area of the fabric Caeli has and want to use and design = 10 square feet
Height of the rectangle of the rectangle shape = 2.5 feet
2. What is the base of the flag if she will use all of the fabric she has?
Area of the shape of the rectangle = Height of the flag * Base of the flag
Replacing with the real values:
10 square feet = 2.5 feet * Base of the flag
10 square feet/2.5 feet = Base of the flag
<u>Base of the flag = 4 feet</u>
<u>If Caeli will use all of the fabric she has, the base of the flag should be of 4 feet.</u>
