Answer:
he sum of the first number and the square of the second number is 18. The difference between the square of the second number and twice the first number is 12.
I know the first set of equations would be x+y2=18 and y2−2x=12, and we can get x=2 and y=2 or y=−2.
My question is about how to understand difference when making equations. I know it means subtraction but would you ever use absolute values when making the equation?
For example, if I said the difference between a number x and 7 is 3, then wouldn't there be two answers? I would think of it as |x−7|=3 and then we could get two answers: x=10 and x=4. My rationale is that on the number line, the distance between either of my x values and 7 is 3.
In the quoted question I began with, then I could get the numbers of x=10 and y=22–√ or y=−22–√ but that's only if I did |y2−2x=12| and I don't feel that's right.

If each block sides are 1 cm long, what is the volume of this object?
4 cubic centimeters.
Brainliest would be great. Comment below if it helped!
Answer:
The volume for this object is 4.
Step-by-step explanation:
For each block, we need to multiply using the volume formula which is
Length x Width x Height
So, if the side lengths for all these blocks are 1. That means we would do 1x1x1 for every block. Since there are 4 blocks that means our equation for the whole object would be 1+1+1+1 or simply 1x4. And we all know the answer to our equation 1 x 4 is 4.

Shannon says that the lines y=-3x-4, y = -x + 6, y = -4x - 5, and y=-x-5 could represent the sides of a rectangle. Explain Shannon's error.
The adjacent sides of rectangle form 90° to each other or are
perpendicular, while the opposite sides are parallel.
The error, is that the coefficient of x, in the four equations can only take on two values, such that if one of the values is m, the other will be [tex]-\dfrac{1}{m}[/tex]
Reasons:
In a rectangle, the adjacent sides are perpendicular to each other, while
the opposite sides are parallel.
The slope of parallel lines are equal, and the slope, of a line perpendicular to another line with slope, m, is [tex]-\dfrac{1}{m}[/tex], therefore the slopes of the parallel sides should be equal, which gives;
The equations should consist of two pairs of equations of lines with equal slopes, such as the pair, y = -x + 6, and y = -x - 5The slope of the other two lines should therefore be [tex]-\dfrac{1}{-1} = 1[/tex], which gives the equations of the other two lines as y = x - 4, and y = x - 5, respectively.Therefore;

Step-by-step explanation:
You can make this easier by taking the expanded form of 398:
300 + 90 + 8
7 x 300 = 2100
7 x 90 = 630
7 x 8 = 56
Then add all these values together:
2100 + 630 + 56 = 2,786

Answer:
[tex]x=61[/tex]
Step-by-step explanation:
We can find the angle directly above the [tex]2x+8[/tex].
We know that because they both lie on a straight line, the other angle is [tex]180-(2x+8)=172-2x[/tex].
Aha! We have a path to the solution!
[tex]172-2x=x-11[/tex] because of the parallel line angle theorem(I forget what it's called).
We then add [tex]2x[/tex] and [tex]11[/tex] to both sides to get [tex]183=3x[/tex].
Lastly, we divide by [tex]3[/tex] to get [tex]61=x[/tex].
So, [tex]\boxed{x=61}[/tex] and we're done!
3 3/4 divided by 2 1/12 in simplest form
Answer: the final answer is 1 4/5 or 9/5
Step-by-step explanation:
First:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
3 3/4 turns into 15/4 and 2 1/12 turns into 25/12
Second: then flip the 2nd fraction so it becomes 12/25
now multiply straight across: 15/4 x 12/25
15 x 12=180
4 x 25=100
180/100= 9/5= 1 1/4
Simplest form of quotient of given fractions is 9/5.
The given fractions are [tex]3\frac{3}{4}[/tex] and [tex]2\frac{1}{12}[/tex].
How to divide two fractions?Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.
[tex]3\frac{3}{4}[/tex] can be written as [tex]\frac{15}{4}[/tex] and [tex]2\frac{1}{12}[/tex] can be written as [tex]\frac{25}{12}[/tex].
Keep 15/4 and change division sign to multiplication sign and reverse the fraction 25/12 as 12/25.
That is , [tex]\frac{15}{4} \div \frac{25}{12} = \frac{15}{4} \times \frac{12}{25}[/tex]
[tex]=\frac{3}{1} \times \frac{3}{5} =\frac{9}{5}[/tex]
So, quotient = 9/5
Therefore, simplest form of quotient of given fractions is 9/5.

Roger paid $27.50 for a sweatshirt. This amount includes a sales tax of 10%. What was the cost of the sweatshirt before tax?
Answer:$25.00
Step-by-step explanation:
Net Amount (excluding tax) $25.00
Tax (10.0%) $2.50
Gross Amount (including tax) $27.50
in short 10% tax of $25.00 is $27.50.
The required cost of the sweatshirt before tax s given as $24.50.
What is the percentage?The percentage is the ratio of the compositions of matter to the overall composition of matter multiplied by 100.
Here,
Roger paid $27.50 for a sweatshirt. This amount includes a sales tax of 10%.
Cost of the sweatshirt before tax = 27.50 - 10% of 27.50
= 27.50 - 0.1× 27.50
= $24.50
Thus, the required cost of the sweatshirt before tax s given as $24.50.

A shipping box is 12 inches by 18 inches by 16 inches the shipping box will be filled with smaller boxes each boxes each smaller box is 3 inches by 2 inches by 4 inches
The number of small boxes that will fill the truck will be 144 boxes
The formula for calculating rectangular box is expressed as:
V = LWH
L is the length
W is the width
H is the height
For the large box
Volume = 12 * 18 * 16
Volume = 3,456 cubic inches
For the small box:
Volume of the small box = 3 * 2 * 4
Volume of the small box = 24 cubic inches
Number of small boxes that will fill the truck = 3456/24
Number of small boxes that will fill the truck = 144
Hence the number of small boxes that will fill the truck will be 144 boxes

Arrange the following inequality into slope-intercept form. Then, describe what type of boundary line would be used and where to shade.
6x > 2y ‒ 5
Answer:
To put this equation in point slope form, we want an equation of the form y=mx+b or in this case, y< mx+b or y< mx+b. To isolate y, we divide through by 2 and move the 5/2 to the other side, so the equation becomes 3x+5/2 > y. So, since we are interested in all values of y that are less that 3x+5/2 we would shade the region below the line. Since y=3x+5/2 is not a solution to the inequality since it is strictly less, we would need a dashed boundary line since the boundary is not included.
Step-by-step explanation:
If m∠10 = 70, then find the m∠14 and state the angle relationship.
The measure of m∠14 is 110 degrees and the angle relationship is a supplementary angles
Let us assume that angle m∠10 and m∠14 are supplementary, this means that the sum of both angles will be 180 degrees.
Since the angles are supplementary, hence the required expression will be:
m∠10 + m∠14 = 180
Given that m∠10 = 70 degrees
70 + m∠14 = 180
m∠14 = 180 - 70
m∠14 = 110 degrees
Hence the measure of m∠14 is 110 degrees and the angle relationship is a supplementary angle.
