Answer:
A.
Step-by-step explanation:
In order to find the cost of the wallpaper per square foot, we must do 700.92 divided by the area of the wallpaper.
Area = length times width
Area of wallpaper = 12*9=108
700.92/108 = 700.92/108 = 6.49
The cost per a square foot is $6.49, so the answer is A.
Hope this helps :)

Answer:
19. 3x+5/2x+7 =5
or, 3x+5=5×(2x + 7)
or, 3x + 5 = 10x + 35
or, 5 - 35 = 10x - 3x
or, -30 = 7x
or, -30/7 = x
21. let x be the other number
we know,
or, x × 1/7 =2
or, x/7 =2
or, x = 14
therefore, the other number is 14.
