Answer:
Step 2: Commutative Property
Step 3: Associative Property
Step-by-step explanation:
According to the Commutative Property of Addition: Two real numbers can be added in either order.
a + b = b + a
Therefore, she used the Commutative Property in Step 2.
In Step 3, she used the Associative Property, in which the grouping of the addends does not change the sum.

Determine what comes next in the given pattern 41,39,37,35,33
Answer:
31
Step-by-step explanation:
you're just subtracting by two's as the pattern goes on.
In the given pattern 41,39,37,35,33,the next number in the pattern is 31. To determine what comes next in the given pattern,let's observe the sequence:
41, 39, 37, 35, 33
The pattern is a decreasing sequence where each number is subtracted by 2 to get the next number.
So, to find the next number, subtract 2 from the last number in the sequence: 33 - 2 = 31
The next number in the pattern is 31.

Write the equation of a line that goes through the point (2, 4) that is parallel to the
line y = 3x - 6.
Answer:
y = 3x - 2
Step-by-step explanation:
Parallel lines have the same gradient in this case 3 is the gradient.
We will use the point (2,4) to form our own equation.
4 will be y, 3 will be m, 2 will be x
All we need is to find the C in the equation y=mx + c
4 = 3(2) + c
4 = 6 + c
C = -2
Therefore;
y = 3x - 2

how to solve y=-10x+3?
9514 1404 393
Answer:
top down: 13, 3, -7, -47
Step-by-step explanation:
You evaluate any equation by putting the numbers in place of the corresponding variables and following the rules of arithmetic.
For x = -1, put -1 where x is and do the math.
y = -10(-1) +3 = 10 +3 = 13
For x = 0, put 0 where x is and do the math.
y = -10(0) +3 = 0 +3 = 3
For x = 1, put 1 where x is and do the math.
y = -10(1) +3 = -10 +3 = -7
For x = 5, put 5 where x is and do the math.
y = -10(5) +3 = -50 +3 = -47
The table values are 13, 3, -7, -47.
Ryan is driving on a long road trip. He currently has 13 gallons of gas in his car. Each hour that he drives, his car uses up 1.25 gallons of gas. How much gas would be in the tank after driving for 4 hours? How much gas would be left after t hours?
Answer: gas left after 4 hours :8
Gas left after t hours: 13-1.25t
Step-by-step explanation:
The gas left after 4 hours will be 8 gallons and expression for the gas left after t hours will be 13 - 1.25 t.
It is given that Ryan has 13 gallons of gas in his car and car uses 1.25 gallons of gas per hour.
We have to find out the amount of gas left after 4 hours and expression for the gas left after t hours.
What do you mean by algebraic expressions ?
The algebraic expressions are those which are made up of variables, constants and algebraic operations i.e., addition, subtraction, etc.
As per the question ;
Ryan has 13 gallons of gas in his car.
The gas used per hour = 1.25 gallons
The gas used by car in 4 hours will be ;
= 1.25 × 4
= 5 gallons
So ,
The gas left after 4 hours will be equal to ;
= 13 - 5
= 8 gallons
Also ;
The gas left after t hours can be represented by equation ;
= 13 - 1.25 t
Thus , the gas left after 4 hours will be 8 gallons and expression for the gas left after t hours will be 13 - 1.25 t.

What is the GCF of (4+16) using the distributive property?
Answer:
20
Step-by-step explanation:
The GCF of 4 and 16 is 4.
[tex] \frac{4}{4} = 1 [/tex]
[tex] \frac{16}{4} = 4 [/tex]
We can rewrite this using the distribute property like so:
[tex] 4(1 + 4)[/tex]
Using the distribute property:
[tex] = 4 + 16[/tex]
[tex] = 20[/tex]
We can also add inside the parentheses and multiply we'll get the same answer.
[tex] = 4(5) \\= 20[/tex]

What is the remainder when 2^81 is divided by 17? Need 3 answer with solution!
==========================================================
Explanation:
Note that 2^4 = 16 is one less than 17.
Because of this nature of being 1 less, we can say the remainder of 16/17 is -1 because it comes up one short.
In terms of modular arithmetic, we can say,
[tex]2^4 \equiv 16 \ (\text{mod } 17)\\\\2^4 \ \equiv -1 (\text{mod } 17)\\\\[/tex]
Then let's raise both sides to the 20th power. I'm picking 20 because 20*4 = 80 which will help build toward 81
[tex]2^4 \equiv -1 \ (\text{mod } 17)\\\\\left(2^4\right)^{20} \equiv (-1)^{20} \ (\text{mod } 17)\\\\2^{20*4} \equiv 1 \ (\text{mod } 17)\\\\2^{80} \equiv 1 \ (\text{mod } 17)\\\\[/tex]
Lastly, we'll multiply both sides by 2 to get to the final answer
[tex]2^{80} \equiv 1 \ (\text{mod } 17)\\\\2*2^{80} \equiv 2*1 \ (\text{mod } 17)\\\\2^{1}*2^{80} \equiv 2 \ (\text{mod } 17)\\\\2^{1+80} \equiv 2 \ (\text{mod } 17)\\\\2^{81} \equiv 2 \ (\text{mod } 17)\\\\[/tex]
So if we were to divide 2^81 over 17, then we get some quotient and a remainder of 2

Do you think the difference of 1.4-0.95 is less than one or greater than one? Explain.
Answer:
The answer would be , less than one .
The difference of 1.4 - 0.95 is less than one as per the concept of subtraction.
To determine this, we can simply subtract the two values:
1.4 - 0.95 = 0.45
Since the result of the subtraction is 0.45, which is less than one, we can conclude that the difference of 1.4 - 0.95 is indeed less than one.
In numerical terms, the difference is 0.45, which is 45 hundredths or less than half of one whole unit.
When comparing the two original values, 0.95 is almost half of 1.4, making the difference smaller than one.
In summary, the difference of 1.4 - 0.95 is less than one, specifically 0.45. It is essential to pay attention to the decimal values and their magnitudes when determining the difference between two numbers.

Step-by-step explanation:
Suppose you deposit $200 in a savings account that earns 4% per year. Find the simple interest earned in 2 years. Then find the total of principal plus interest.
9514 1404 393
Answer:
interest: $16account total: $216Step-by-step explanation:
The amount of interest is given by the simple interest formula:
I = Prt . . . . where P is the amount earning interest, r is the annual rate, t is the number of years
I = $200·0.04·2 = $16.00
The simple interest earned in 2 years is $16.00.
__
The total of principal and interest is found by adding those values:
$200.00 +16.00 = $216.00
The total amount is $216.00.
