Step-by-step explanation:
11) A
The ratio of texts sent to calls made was 8:5.
12)
Noah 4 scoops of powder with 6 cups of water
4/6*100%=66.67%
Andre mixes 5 scoops of powder with 8 cups of water.
5/8*100%=62.5%
it can be seen that Noah's mixture have a stronger orange taste with a concentration of 66.67% while andre's mixture has a concentration of 62.5%.
Answer:
9???
Step-by-step explanation:
6 trophies on the shelves and 3 that are not.
6 + 3 = 9
8×.15=1.2 (how many more each month)
365×1.2=438 (how many for one year)
438×2=876 (two year rate)
876+8= 886 (total mice after two years)

Answer:
A.)
Step-by-step explanation:
The answer that you had chosen is correct, because the number line is stating that you are subtracting 5 from 0, giving you -5. Then it is saying that you are subtracting 2 from that, giving you -7.
B.) is wrong, because they are adding the answer of the correct equation with another number, which would equal -12.
C.) is incorrect, because when you are adding a positive with a negative, you are actually subtracting, not adding. When you are doing this, always keep the sign for the answer (negative or positive) with whatever the larger addend is. So in this letter's situation, the equation would look like this: -5 + 2 = -3.
D.) is incorrect because once again, they are taking the original correct answer and subtracting it from another number, which would be -12.

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.
