simplify -- divide by 2
7:9
X=-6
You plus in x as -6 and you already know that y=5x and you plug in x=-6
It should look like 2(-6)-5(-6)=18

The answer is below
Step-by-step explanation:
She decides the width of the board should be atleast 35% of the length.
Solution:
Let x represent the length of the bulletin board and y be the width of the bulletin board. Since there is 100 inches available, hence:
Perimeter = 2(length + width)
100 = 2(x + y)
x + y = 50
Also, since the width is 35% of the area, hence:
y = 35% of x
y = 0.35x
Since:
x + y = 50
x + 0.35x = 50
1.35x = 50
x = 37.04
x ≅ 38 inches to the next whole number
x + y = 50
y = 50 - 38
y = 12 inches
The bulletin board is 38 inches by 12 inches
