Answer:
<h2><u>
X= 1</u></h2>
Step-by-step explanation:
<em>y = 5 - 3x</em>
<em>5x - 4y = -3</em>
you substitute for y since you know what y equals.
so, it will then be
5x -4(5 -3x) = -3
you then multiply -4 by everything in the parenthesis
so then it will be
5x - 20 + 12x = -3
Then combine like terms
5x + 12x = 17x
then the new equation is
17x -20 = -3
the next step is to and 20 to both sides since it is negative you do the opposite.
17x - 20 = -3
<u> + 20 +20</u>
17x = 17 divide 17 by both sides sice 17 is being multiplied by x you do the opposite and divide and you get 1.
<h2><u>
so, X = 1</u></h2>

Answer:
77.74 square feet
Step-by-step explanation:
1. We have to keep the triangle and the rectangle apart and find the area of each separately then add the areas together.
The formula for the area of a rectangle is height x width = area
So, 6.5 feet x 10.4 feet = 67.6 feet squared
The formula for the area of a triangle is height x width x (1/2) = area
So, 5.2 feet x 3.9 feet x (1/2) = 10.14 feet squared
Now, add the two areas together.
10.14 square feet + 67.6 square feet = 77.74 square feet
