Answer:
3x - 20 = 5
Step-by-step explanation:
Answer:
We need to find length and width. To find two unknowns we need two equations.
P = 2L + 2W = 34
L = W + 3
34 = 2(W + 3) + 2W
34 = 2W + 6 + 2W
28 = 4W
W = 7
L = 7 + 3 = 10
The length is 10 inches and the width is 7 inches.
Step-by-step explanation:
1.
<span>1.5x-1 > 6.5
1.5x>1+6.5
</span>1.5x>7.5, divide by 1.5
x>5, is represented by the region to the right of the vertical line x=5
2.
<span>7x+3 < -25
7x<-25-3
7x<-28, divide by 4:
x<-4
</span>x<-4, is represented by the region to the left of the vertical line x=-4
