Answer:
12 toppings
Step-by-step explanation:
There's a 60 cent difference in the base price, and the price of toppings is a 5 cent difference, so it would take 60/5 or 12 toppings to make up the difference. r, you can make a chart. Or you can do algebra and solve an equation:
6.75 + .75 x = 6.15 + .8x where x is the number of toppings. Subtract 6.15 from both sides.
.60 + .75x = .8 x Subtract .75x from both sides
.60 = .05x Divide both sides by .05
I would say, well I THINK It's 2
We can solve this by looking at pairs that equal 60.
6 and 10 get to 60 when multiplied. Let's see if it fits in as a perimeter.
12+20=32
So the width and length of the room is 6 meters and 10 meters.
7b-6(11-2b)=10
The first step is to distribute. Multiply each number inside the parentheses by -6.
7b + (-6*11) + (-6*-2b) = 10
7b - 66 + 12b = 10
Now combine like terms.
19b - 66 = 10
Add 66 to both sides.
19b = 76
Divide both sides by 19.
b = 4
The answer is b = 4.
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.
