When multiplying two variables, how is using the
Distributive Property similar to using a table?
Newton's third law states that if object A exerts a force on object B, object B must respond with a force of equal size and in the opposite direction. This law reflects nature's symmetry: forces always exist in pairs, and one body cannot exert a force on another without experiencing one.
The distributive property of multiplication over addition can be used when you multiply a number by a sum. For example, suppose you want to multiply 3 by the sum of 10 + 2. 3(10 + 2) = ? According to this property, you can add the numbers and then multiply by 3.

In the following pictograph, how many more books has Group 1 read than Group 4?
a. 9
b. 3
c. 18
d. 6
Answer:
First, we need to find how many books there are in each group;
If we look at group 1, they have 18 books.
If we look at group 4, they have 9 books. (We got this because they have 6 whole books, and they have half of a those 6 books which is 3 books in the other book symbol, so combined: 6 + 3 = 9)
18(group 1) - 9(group 4) = 9, group 1 read 9 more books.

Jennifer has a beginning balance of $4,750 in her Checking account. After depositing a paycheck (p), she writes a check (c), and another check (d). After writing the checks, she withdraws money from an ATM (a), then gets refunded some money (r) for returning a pair of shoes she bought. Write an Algebraic Expression that models the situation.
Answer:
An Algebraic Expression that models the situation is [tex]4750+p-c-d+r[/tex]
Step-by-step explanation:
Beginning balance of Jennifer=$4750
Now she deposits a paycheck = p
So, New balance = 4750+p
Now she writes a check = c
Remaining balance = 4750+p-c
Now she writes a check = d
Remaining balance = 4750+p-c-d
Now refunded some money (r) for returning a pair of shoes she bought.
New balance = 4750+p-c-d+r
Hence an Algebraic Expression that models the situation is [tex]4750+p-c-d+r[/tex]
solve for n if s = 540 Enter the value in the box.
180(n − 2) = s
Answer:
n = 5
Step-by-step explanation:
180(n − 2) = s
180(n − 2) = 540
180n - 360 = 540
180n - 360 + 360 = 540 + 360
180n = 900
(1/180) 180n = 900 (1/180)
n = 5
The gas tank in Feliz's car is 5/6 full. Each time he drives to or from work, he uses 1/12 of a full tank of gas. Which equation represents the number of times Feliz can drive to or from work with his gas tank? A) 5/6 ÷ 1/12 = 10 B) 1/12 ÷ 5/6 = 7 C) 1/12 ÷ 5/6 = 1/10 D) 5/6 ÷ 1/12 = 5/72
Answer:
A 5/6 ÷ 1/12 = 10
Step-by-step explanation:
Let the full tank be represented with 'Y'
Feliz's car is 5/6 full
Whenever he drives To and From work he uses 1/12 of the full tank gas.
That is 1/12 of y
Since the tank was 5/6 full before his journey to and from work, the number of time he can use the gas will be
5/6 ÷ 1/12
5/6×12/1
= 10
Feliz can drive to or from work with his gas tank 10 times.

Consider the figure. Determine the value of w.
Answer:
w=67°
Step-by-step explanation:
First you solve for x. 12x+11=x. X would be 1. Then you plug in 1 for x and add the w to the equation. 12(1)+11+w=90. after solving that you will get the total for w. which should be 67°
Answer:
43°Step-by-step explanation:
We observe on the picture that:
(12x + 11)° and 47° are vertical angles and vertical angles are equal as per definitionAngle w° is complementary angle with (12x + 11)° and complementary angles add to 90° as per definitionTherefore
w = 90°- (12x + 11)°w = 90° - 47°w = 43°Evaluate for a = 2 and b = 3.

Nine cards are numbered from 1 to 9 and placed in a box. One card is selected at random and not replaced. Another card is randomly selected. What is the probability of selecting two prime numbers?
Answer:
1/6
Step-by-step explanation:
There are 4 primes. So the probability for the first draw is 4/9. Since the card is not replaced, the second probability is 3/8. 3/8 * 4/9 is 12/72, which simplifies into 1/6.
Answer:
1/6
Step-by-step explanation:
There are 4 possible primes: 2, 3, 5, 7
First card has 4/9 probability of being a prime. Second card has 3/8 probability of being a prime(since 3 prime cards left and 8 total cards left because we do not replace the first card). 4/9 * 3/8 = 1/6.
Another way to do this is using combinatorics. C(9,2) = 36 ways to choose 2 distinct cards, C(4,2) = 6 ways to choose two of the "prime" cards. 6/36 = 1/6.

3. Jacki Marshall owes a balance of $5,000 on one credit card that charges 19 percent interest. She can pay off the balance in two years with monthly payments of $252.04. She has another credit card with a balance of $7,500 that charges 20 percent interest.
She can pay off the balance in two years with monthly payments of $381.72. Jacki owns a home valued at $150,000. She can get a home equity loan for $12,500 at 8 percent interest. Jacki can repay the loan in two years with monthly payments of $565.34. How much money will Jacki save if she takes out a home equityloan to pay off the credit card balances?
Answer:
1. $56,000
2. $3,695
3. $1,644.48
Step-by-step explanation:
1. Equity = valuation - mortgage
= $250,000 - $180,000
= $70,000
80% = 80/100 = 0.8
Therefore, 80% of the equity = 0.8 × $70,000
= $56,000
2. Total charges = jewelry charge + electronics charge
= $2,450 + $1,245
= $3,695
3.
First credit card:
Total payment = two years × monthly payments
= 2 × 12 × $252.04
= $6,048.96
Interest = total payment - balance
= $6,048.96 - $5,000
= $1,048.96
Second credit card:
Total payment = two years × monthly payments
= 2 × 12 × $381.72
= $9,161.28
Interest = total payment - balance
= $9,161.28 - $7,500
= $1,661.28
Home equity loan:
Total payment = two years × monthly payments
= 2 × 12 × $565.24
= $13,565.76
Interest = total payment - balance
= $13,565.76 - $12,500
= $1,065.76
Money saved = (total of interest from credit cards) - home equity loan interest
= ($1,048.96 + $1,661.28) - $1,065.76
= $1,644.48

Graph the line with slope of 5/3 and goes through the point (2,1).
Answer:
so graph your first point. (x=2, y=1)
Step-by-step explanation:
Your 5/3 is your rise over run. So go up 5 from 2 you should be at 7 and over 3 from your 1 so your next point would be (x=7, y=4) now get a ruler and connect your two points. make sure to use a ruler to make your line straight.
To graph a line with a slope of 5/3 and passes through the point (2, 1), we can use the slope-intercept form of a linear equation, which is given by:
y = mx + b
where:
- y and x are the coordinates of any point on the line
- m is the slope of the line
- b is the y-intercept (the point where the line crosses the y-axis)
Given the slope (m = 5/3) and the point (2, 1), we can substitute these values into the equation and solve for the y-intercept (b):
1 = (5/3)(2) + b
1 = 10/3 + b
To isolate b, we subtract 10/3 from both sides:
1 - 10/3 = b
-7/3 = b
Now we have the values of m and b, so we can write the equation of the line:
y = (5/3)x - 7/3
To graph the line, we plot the y-intercept at (0, -7/3), and then use the slope (5/3) to find additional points on the line.
Since the slope is positive, we can move up 5 units vertically and 3 units horizontally from the y-intercept to find another point. We repeat this process to find more points if needed.
Thus, using this, one can plot the graph.

Quadrilateral ABCD is a parallelogram. Determine the measure of Angle A
A) 96°
B) 52°
C) 39°
D) 78°
Answer:
[tex]\huge\boxed{\text{(A)}\ 96 \textdegree}[/tex]
Step-by-step explanation:
A parallelogram has two pairs of identical angles.
The identical angles will be directly opposite from each other.
This means that:
Angle C = Angle AAngle D = Angle BTherefore, we can say that Angle A is 3x degrees and Angle B is x+52 degrees.
It's also important to note that all angles in a quadrilateral add up to 360°.
Since we know the measure of each angle, we can add up the expressions for each and find x.
[tex]3x + 3x + (x+52) + (x+52) = 360[/tex]
Let's simplify this equation.
[tex]6x+(x+52)+(x+52)=360[/tex] [tex]8x+104=360[/tex] [tex]8x=256[/tex] [tex]x=32[/tex]Now that we know the value of x, let's use it to find the measure of Angle A.
We already proved earlier that Angle C is equivalent to Angle A. Since we know the expression for Angle C (3x) it'll be the same for angle A.
[tex]3(32)=96[/tex]
So A is 96°

Step-by-step explanation:
how I see the problem I just put the 1 over the 8 because you can't really do anything else with the problem
The inverse f'^{-1}x of the given function is x/8
Given the function y = 8x, we are to find the inverse of the function.
Replace y with x
x = 8y
Make y the subject of the formula
x = 8y
Divide both sides by 8\
x/8 = 8y/8
x/8 = y
Swap sides
y = x/8
