Which expression uses the commutative property to make it easier to evaluate -12 · 13 · 1/3?
A. 12 · 13 · 1/3
B. -12 · 1/3 · 13
C. -1/3 · 13 · 12
D. 1/3 · 13 · (-12)
Answers
Answer:
Not sure it's either B. or D I put B.
Step-by-step explanation:
The commutativity property is used to get
-12×13×1/3 = -12×1/3×13
What is Commutative property?According to mathematics, an arithmetic operation is commutative if switching the operands' positions has no effect on the computation's outcome.
When two numbers A and B are provided, the commutative property of the numbers formula is as follows:
A+B=B+A
A×B=B×A
A-B≠B-A
A÷B≠B÷A
According to the commutative property formula, the outcome is unaffected by the sequence in which two integers are added or multiplied. However, the order of the integers matters for subtracting and dividing any two real numbers, thus it cannot be altered.
How to solve?The commutativity property is used to get
-12×13×1/3 = -12×1/3×13
such that the evaluation becomes easier, which is to get 12×1/3=4.
The commutativity property is used as follows:
-12×(13×1/3)=-12×(1/3×13)

Kiran's mother gets a restaurant bill for $25. She has a coupon for 15%. After the discount is applied, she adds 20% as a tip. What is the total after the discount and tip? (don't forget the $)
Answers
Answer:
$25.50
Step-by-step explanation:
So we have a 15% off coupon. We can multiply 25×.85 to find our new price.
Our total is now $21.25
Now to find the tip do $21.25 +(.2 × 21.25)
*The .2 is 20 percent of our discount price.*
We then get $25.50

Answers
D
Step-by-step explanDAdadadad
Answer:
Pretty sure the Answer is:
=XOR(B4=12;C4<9) and =AND(B4=12;C>9) return TRUE, if the value in cell B4 is 12 and the value in C4 is 29.
Step-by-step explanation:
An =XOR function returns TRUE if any of the clauses in it are true, while an =AND function returns true only if both are true. Therefore, since in =XOR(B4=12;C4<9) B4 does equal 12, since this is an =XOR function. =AND(B4=12;C>9) is correct because B4 = 12 and C4 is greater than 9.

Milan will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $48 and costs an additional $0.20 per mile driven. The
second plan has an initial fee of $57 and costs an additional $0.15 per mile driven.
For what amount of driving do the two plans cost the same?
What is the cost when the two plans cost the same?
If you do not have both of the answers do not bother to reply.
Answers
For 180 miles of driving the two plans will cost the same, at a price of $84.
Step-by-step explanation:1 - Set up the system of equations
Let x represent the miles driven
Let y represent the cost
First Plan:
y = $48 + $0.20x
Second plan:
y = $57 + $0.15x
Note that both are set equal to y, that means we can substitute y in one equation with the other equation because y = y
2 - Substitute
$57 + $0.15x = y = $48 + $0.20x
$57 + $0.15x = $48 + $0.20x
3 - Get the variables on one side and the constants on the other and then get x alone
$57 + $0.15x = $48 + $0.20x
- $48 - $48
$9 + $0.15x = $0.20x
- $0.15x - $0.15x
$9 = $0.05x
$9/0.05 = $0.05x/0.05
x = 180 Miles
"For what amount of driving do the two plans cost the same?
For 180 miles of driving the two plans will cost the same.
4 - Plug 180 in for x in either equation and solve to find the cost at which they equal
y = $48 + $0.20x
y = $48 + $0.20(180)
y = $48 + $36
y = $84
"What is the cost when the two plans cost the same?"
$84 is the cost when the two plans cost the same
Hope this helps

We need to find out if triangles ABC and DCB are congruent.
The image shows one tick mark on sides AC and BD, thus they are congruent.
Two tick marks are shown on sides AB and CD, thus they are congruent.
Finally, both triangles share the side BC.
Being all three sides congruent, the triangles are congruent by the SSS (side-side-side) congruence theorem.
