Answer:
They are NOT equivalent.
Step-by-step explanation:
To find if the expressions are equivalent, we have to simplify the first expression.
Solve:
-8 - 2(3 + 2x) + 7x
Use the distributive property.
-8 - 6 - 4x + 7x
Combine like terms.
-14 - 4x + 7x
-14 + 3x
Since they're not the same, this means that the expressions are NOT equivalent to each other.

Answer:
[tex]\dfrac{x}{2}+\dfrac{1}{3}[/tex]
Step-by-step explanation:
We need to find the value of [tex]((\dfrac{1}{4}x+\dfrac{3}{4}x-\dfrac{1}{2}x)+1+(\dfrac{-2}{3}))[/tex]
We can solve it as follows :
[tex]((\dfrac{1}{4}x+\dfrac{3}{4}x-\dfrac{1}{2}x)+1+(\dfrac{-2}{3}))\\\\=(\dfrac{x+3x-2x}{4})+1-\dfrac{2}{3}\\\\=\dfrac{2x}{4}+\dfrac{1}{3}\\\\=\dfrac{x}{2}+\dfrac{1}{3}[/tex]
Hence, the value of [tex]((\dfrac{1}{4}x+\dfrac{3}{4}x-\dfrac{1}{2}x)+1+(\dfrac{-2}{3}))[/tex] is equal to [tex]\dfrac{x}{2}+\dfrac{1}{3}[/tex].

Which of the following of appropriate units of measure to use when finding the mass of a pencil?
a. kilograms
b. meters
c. Grams
d. centimeter
Answer:
Grams
Step-by-step explanation:
Mass is the amount of matter present inside a solid. Kilograms and grams are the units to measure mass of an object.
For pencil, the unit to measure its mass is grams. As its mass is less, we can use smaller unit.
Hence, the correct option is (c) "grams"

A printer need to make a poster that will have a total poster area of 200 in^2 and will have 1 inch margins on the sides, a 2-inch margins on both the top and the bottom. What dimensions will give the largest printed area?
Answer:
The dimensions that will give the largest printed area of 132.1669 in^2 are
= Length x Width
= 15.20829 * 8.69045
Step-by-step explanation:
a) Data and Calculations:
Total poster area = 200 in^2
Side margins = 1 inch each
Top and bottom margins = 2 inches each
Let x = length of the full poster
then 200/x = width of the full poster
Therefore, the length of the printed area = x - 3.5
and the width of the printed area = (200/x)-2
Therefore, the Area of the Printed space = (x-3.5)((200/x)-2)
Solving for the Area (A) of the printed space, we have
A = (x-3.5)(-200/x2) + ((200/x)-2)
A = 700 -2x2
If the derivative is set to 0, we have:
0 = 700 -2x2
700 = 2x2
350 = x2
x = 18.70829 The original length
width = 10.69045
Therefore, the area of space available for printing is
15.20829 * 8.69045
= 132.1669 in^2
It’s estimated that 800 people would attend the play, but 752 people actually attend.
What is the percent error, to the nearest percent, of the estimate? Enter the answer in the box.
*has blank box* percent error
Answer:
6
Step-by-step explanation:
752/800=0.94
0.94x100=94
100-94=6
The percent error, to the nearest percent, of the estimate is 6%
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
We need to Write the percent as a fraction in simplest form
16.24%
So, we can rewrite it as;
16.24 / 100
16 and 24/100 or 16 6/25
So the percent as a fraction is 16 6/25
Given:
Expected value = 800
Actual value = 752
Now, Percent error
Computation;
Percent error = [(Actual value - Expected value)/Expected value]100
= [(800 -752) / 800]100
= 6%
Therefore, the percentage error will be 6%

Find the probability of getting a numbered card when a card is drawn from the pack of 52 cards.
Answer:
[tex]\frac{9}{13}[/tex]
Step-by-step explanation:
1. the formula is: p=(number_of_numbered_cards)/(total_number_of_cards);
2. the number of total numbers of the cards is 52 (according to the condition); the number of the numbered cards is:
4*(10-2+1)=36 (min is '2'; max is '10').
3. after the substitution:
p=36/52=9/13≈0.692
The slope of the line is m=3/4. One point is (x, 2) and (3,-4)
Find X
Answer:
x is 11
Step-by-step explanation:
We know the slope (3/4) and a point (3,-4), so we can use point-slope form (y-y1=m(x-x1)
Substitute the numbers into the equation
y--4=3/4(x-3)
simplify
y+4=3/4(x-3)
do the distributive property
y+4=3/4x-9/4
subtract 4 from both sides
y=3/4x-25/4
this is the equation of the line.
Since it says that (x,2) is a point in the equation, we can substitute it into the equation
2=3/4x-25/4
add 25/4 to both sides
33/4=3/4x
multiply by 4/3
11=x
we can double check by plugging (11,2) into the equation of the line.
2=3/4(11)-25/4
2=33/4-25/4
2=2
it works! :)
Hope this helps!

what is the equation of a line that passes through the points -3,5 and has the slope of zero
Answer:
All lines with zero slope is a horizontal line.
y=mx+c slope is m. If m were zero, any x value substituted in would make y=(0)x+c, y=c.
Sub in the values 5=(0)(-3)+c, c would then be 5. So the equation would be y=5.

The following is known about three numbers: If the second number is subtracted from the sum of the first number and 3 times the third number, the result is 2. The third number plus 3 times the first number is -1. The first number plus 3 times the second number plus the third number is -16. Find the sum of the three numbers.
Answer:
-6
Step-by-step explanation:
Let the first, second and third number be x, y and z respectively.
We are told that the second number is subtracted from the sum of the first number and 3 times the third number, the result is 2.
Thus;
(x + 3z) - y = 2 - - - (eq 1)
The third number plus 3 times the first number is -1.
Thus;
z + 3x = -1 - - - (eq 2)
The first number plus 3 times the second number plus the third number is -16.
Thus;
x + 3y + z = -16 - - - (eq 3)
From eq 2, we can rearrange to get;
z = -1 - 3x
Putting -1 - 3x for z in eq(1) and (eq 3),we have;
(x + 3(-1 - 3x)) - y = 2
x -3 - 9x - y = 2
-8x - y = 2 + 3
-8x - y = 5
y = -5 - 8x
Putting y = -5 - 8x and z = -1 - 3x into eq(3), we have;
x + 3(-5 - 8x) + (-1 - 3x) = -16
x - 15 - 24x - 1 - 3x = -16
-26x - 16 = -16
-26x = 16 + 16
x = 0
Since y = -5 - 8x, then y = -5 - 8(0)
y = - 5
Also, since z = -1 - 3x, then;
z = -1 - 3(0)
z = -1
The sum of the three numbers are;
x + y + z = 0 + (-5) + (-1) = -6
