Solve y = x + 8 for x.

Answer:

0.25(4x + 7)

Step-by-step explanation:

Answer: There are a total of 297 students in the 7th grade. Rough estimates would say that about half of that number are boys and half are girls. Asking only 50 random girls would be biased because not only would it not be all of the girls (the number of girls would be around 148 or 149) but it would also be ignoring the roughly 148 to 149 boys there are on estimate. The sample would be biased because it would be ignoring the opinions of more than half the seventh grade.

(FULL CREDIT TO maksimylian, I DID NOT WRITE THIS ANSWER)

Answer:

Randomly surveying 50 girls would most likely bring non-seventh-graders into the sample.

The sample also does not take any boys into account, and they most likely make up about half of the seventh-grade population.

The results would not be a representative sample of the population.

Answer:

you just divide

Step-by-step explanation:

Just divide the top of the fraction by the bottom, and read off the answer!

Answer: So what my teacher always told me to do was act like a fraction was a tree. The tree always falls to the left which then outs the fraction as a division problem. You solve the division problem

Step-by-step explanation:

Ok so for example, lets use [tex]\frac{1}{2}[/tex]. Drawing it as a tree it then falls to the left. Therefore it becomes 1 ÷ 2. So 2 can not go into one therefore you need to put a decimal point at the top and add a zero behind the 1 under the bar. The 1 then becomes a 10, therefore 2 can go into 10 5 times. However the answer is not 5. You have to remember to bring the decimal point that you placed before the 5. In conclusion hte answer is .5 . This may be confusing because I am not able to include any photos but hopefully you'll get the point.

If Laura ascends 8 feet, her new position relative to the surface is 24 feet below the surface.

If the direction is same (like coefficients), we add them and if the direction is opposite (unlike coefficients) then we subtract them. The sign can be taken as per our convenience for a particular direction.

Similarly, as given, if Laura is 32 feet below the surface in a cave (say negative direction)

- 32 feet

and then further she ascends 8 feet that is upward direction (say positive direction),

+ 8 feet

then for calculating final distance of Laura position from surface, we get the expression as:

-32 + 8 = - 24

Hence the final result value is negative 24, it means Laura is bellow the surface, by the distance of 24 feet.

The simplified form of the given expression is 75.

The given expression is 675 ÷ (6 + 9 ÷ 3).

We need to simplify the given expression.

PEMDAS is an acronym used to mention the order of operations to be followed while solving expressions having multiple operations. PEMDAS stands for P- Parentheses, E- Exponents, M- Multiplication, D- Division, A- Addition, and S- Subtraction

Now, in the given expression simplify the bracket.

That is, (6 + 9 ÷ 3)=(6+3)

=9

Now, 675 ÷ 9=75

Therefore, the simplified form of the given expression is 75.

Two times.

Or four times if the rectangle happens to be a square.

Answer:

(17, -11)

Step-by-step explanation:

Please see the attached picture for full solution.

Step-by-step explanation:

Given that the initial charge/fee for the first 5 minutes is $6

and also the additional rate per minutes is $0.6

we can model the total charges after the equation of a straight

that y= mx+c

now using the required notation

C= 0.6t+ 6

comparing this with the equation of a straight line

the constant term c is $6 flat rate for the first 5 minutes

the gradient 0.6 is m

the dependent variable x is t

and the cost C is y  

Answer:

i believe its c=0.60t+3

Answer:

(4,3)

Step-by-step explanation:

This doesn't even take any math really, just deductive reasoning :)

We know the line segment stretches from one to 15, meaning there are 14 points on the line as there is (1,2,3, etc.)

14/2 obviously equals 7, so just plug it in from there.

12 is too far up on the line to be less than half, so (12, 3) is wrong

^ this goes for (9, 3) as well

7 is literally the halfway marker, so there is no way it could be (7, 3)

Making the answer (4, 3) because not only is it the last one remaining but it makes the most sense, being less than one half of the segment

A straight line is 180 degrees:

25x + 8 + 9x + 2 = 180

Combine like terms:

34x + 10 = 180

Subtract 10 from both sides:

34x = 170

Divide both sides by 34:

X = 5

Now solve the smaller angle:

9x + 2 = 9(5) + 2 = 45 + 2 = 47

They angle with the y is a vertical angle to 47 so needs to also equal 47:

7y + 5 = 47

Subtract 5 from both sides:

7y = 42

Divide both sides by 7:

Y = 6

Answer: x = 5, y = 6

-p^2-6r^2-2r-8

Step-by-step explanation:

When you simplify it you get that. Hope this helped :)

The solution to the given expression is -8 - 2r - p² - 6r² which is determined by performing the arithmetic operation.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The given expression is given in the question

(10 – 7r - p²) + (-6r² - 18 +5r)

Open the parentheses and rearrange the terms,

10 - 18 - 7r + 5r - p² - 6r²

Apply the arithmetic operation in the likewise terms,

-8 - 2r - p² - 6r²

Therefore, the solution to the given expression is -8 - 2r - p² - 6r²
