Find the value of x that makes the equation true:
16 - x = 4
x = 18
x = 20
x = 14
x = 12
Answers
16 - 12 = 4
x = 12
16 - x = 4
x = 12
Given the figure below, find the values of x and z.
Answers
Answer:
Value of :x = 12°z = 101°By using the Vertically Opposite Angles property
79 = 6x + 7 where value we get is x = 12
By using Linear pair property
79 + z = 180 where we get the value of z = 101

What percentage of Americans would you predict wear glasses?
Answers
Answer: 64%
75% of adults use some sort of vision correction. About 64% of them wear eyeglasses, and about 11% wear contact lenses, either exclusively, or with glasses. Over half of all women and about 42% of men wear glasses.
63.8% of Americans are predicted to wear glasses
How to determine the percentage?The given parameters are:
Glasses = 638Sample size = 1000The percentage of Americans that wear glasses is calculated as:
Percentage = Glasses/Sample size
This gives
Percentage = 638/1000
Evaluate the quotient
Percentage = 0.638
Express as percentage
Percentage = 63.8%
Hence, 63.8% of Americans would wear glasses

Answers
the average can be calculated by adding the scores together and then dividing by the number of scores.
we can set up an equation:
let x = test score needed on next test
(72+72+80+x)/4 = 71
multiply both sides by 4
72+72+80+x = 284
add like terms
224+x=284
subtract 224 from both sides
x=60
she will need a 60 for her average to be 71
She needs to score a 60 to have a average score of 71,
72+72+80+60=284
284/4=71

A new online music service has a collection of 1,500 songs. It expects to triple the number of songs each year for the next few years. Write an equation representing the relationship, where x is time in years, and y is the number of songs available.
Answers
Answer: y = (3^(x-1))*1500
Step-by-step explanation:
We want the relationship
y = f(x)
where y is the number of songs, and x is the number of years.
We know that in the first year, x = 1, the site has 1,500 songs.
The next year, x = 2, the number of songs is tripled, then we will have:
1,500*3 = 4500 songs.
The next year, x = 3, we will have: 3*(3*1500) = (3^2)*1500.
when x = 4, the number is tripled again:
3*(3^2)*1500 = (3^3)*1500
We already can see the pattern, for the year x, the site will have:
y = (3^(x-1))*1500 songs.
This is the equation we are looking for.

46 people are going to the beach. Nine people can ride in each van. How many vans are needed?
Answers
Answer:
6
Step-by-step explanation:
No. of people going to beach = 46 .
Using Unitary Method ,
9 people can go in one van .
1 person can go in 1/9
46 people can go in 1/9 * 46 = 5.1
Since vans can't be in fraction , 1 extra van for 1 person is need that is for 46th person .
So total number of vans = 5 + 1 = 6

Note: Please help, I have been working on this for like 4 days im so tired.
Answers
Answer:
See below.
Step-by-step explanation:
y^2 - 6y + 9 can be changed correctly into y^2 - 2(y)(3) + 3^2.
Up to here, it's correct.
The right side above shows a polynomial that is the square of a binomial.
It factors into (y - 3)^2.
The correct factorization is (y - 3)^2.
The incorrect factorization of the student's solution is the product of a sum and difference.
The product of a sum and a difference is the correct factorization for a difference of squares.
For example, y^2 - 9 is the same as y^2 - 3^2 and is a difference of squares.
It factors into (y + 3)(y - 3), a product of a sum and a difference.

What is the main cause of tides?
A.
Earth's gravitational pull
B.
the moon's gravitational pull
C.
the moon's rotation around its axis
D.
Earth's revolution around the sun
Answers
High tides and low tides are caused by the moon and tides are really all about gravity(hence why all of these answers have gravitational in them). And, when we are talking about "daily tides" it's the moon that causes them.
The moon's gravity draws in various areas of our world as it rotates. Since the moon is just 1/100th the mass of the Earth, it has enough gravity to shift objects about. The ocean on the moon's far side is still trying to bulge out against it. A high tide is what we term this bulge. (Water is easy to move around too)
This is tidal force, and there are differences between high tides and low tides.
The main cause of tides is the moon's gravitational pull.

A small business owner is determining her profit for one month. Her expenses were $230.21 for utilities, $2,679.82 for rent, and $3,975.00 for employee salaries. She made $11,449.27 in sales for the month. What is her profit?
Answers
Her profit would amount to $4564.24 for one month which is determined by subtracting her total expenses from made revenue.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 12 -2 = 10
For the month, she made a revenue of $11,449.27.
To calculate her profit, we have to subtract her total expenses from made revenue.
Her expenses were $230.21 for utilities, $2,679.82 for rent, and $3,975.00 for employee salaries which are given in the question.
Total expenses = 230.21 + 2,679.82 + 3,975.00 = 6885.03
As per the given data, the solution would be:
⇒ Total revenue - Total expenses
⇒ 11,449.27 - 11,449.27
Apply the subtraction operation, and we get
⇒ 4564.24
Therefore, her profit would amount to $4564.24 for one month.
