So the division of a number and -9 or
x/-9
+10=11 or
(x/-9)+10=11
subtract 10 from both sides
x/-9=1
multiply both sides by -9
x=-9

Choices A, C, E
Step-by-step explanation:
The prices are proportional, so divide any price by the corresponding number of pounds to find the unit cost.
$1.47/(3 lb) = $0.49/lb
The unit cost is $0.49 per lb.
Now we look in the choices to see which choice has a unit price of $0.49/lb.
We divide each price by its number of pounds to fund each unit cost. Every choice with a unit cost of $0.49/lb is an answer.
A $0.98/(2 lb) = $0.49/lb Choice A works
B $4.45/(7 lb) = $0.64/lb Choice B does not work
C $2.94/(6 lb) = $0.49/lb Choice C works
D $0.54/(1 lb) = $0.54/lb Choice D does not work
E $3.92/(8 lb) = $0.49/lb Choice E works
Answer: Choices A, C, E
Answer: 
Step-by-step explanation:
The surface area of a rectangle can be calculated with:
The surface area of a trapezoid can be calculated with:
Calculate the area of the base, wich is a rectangle:
There are two equal rectangles, therefore, multiply the area of any of them by 2:
Calculate the area of the other rectangle:
There are two equal trapezoids, therefore, multiply the area of any of them by 2:
Therefore, the surface area will be the sum of all the areas calculated:
