Answer:
$12.50
Step-by-step explanation:
c is cat food d is dog food
3c + 4d = 43
3c + 6d = 54
subtract those to get
2d = 11
d = 5.50
3c + 2d = 3c + 22 = 43
3c = 21
c = 7
c+d = 7 + 5.50 = 12.50
Answer:
The correct options are:
- The closure property of multiplication states that the product of two rational expressions is a rational expression.
- The commutative property only holds true for the multiplication of rational expressions.
- The properties of rational expression multiplication and division are parallel to the properties of rational number multiplication and division.
Step-by-step explanation:
We know that if a and b are two rational expression than :
Closure property of multiplication states that:
a.b is also an rational expression.
Commutative property under multiplication is given by:
a.b=b.a
The commutative property holds only under multiplication and not division since, if a=0 then,
a/b=0
but b/a is not defined.
Also, the property of rational expression are parallel to the properties of rational number.

it is "c" (circumference)
Step-by-step explanation:
i hope this helps, have a good day
42 gallons weigh 7(42) or 294 pounds
<span>each cubic foot weighs 52 pounds </span>
<span>so the number of cubic feet = 294/52 = 5.654 ft^3</span>
