2(2x - 8) should be Gina's expression as it is not equivalent to 4x - 8.
What is a linear equation?A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.
Given, Steven and Gina each wrote an expression, but only Steven’s expression is equivalent to 4x - 8.
∴ Gina's expressions should be the one that is not equivalent to 4x - 8.
After observing the given options and applying distributive properties we conclude that 2(2x - 8) is Gina's expression as it is 4x - 16.

Rebecca Smith was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 863 points. The number of two-point field goals that Rebecca made was 80 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 13 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals Rebecca Smith made during the 2006 regular season.
Answer:
Number of free throws = 155,
Number of two-points field goals= 168
Number of two-points field goals= 124
Step-by-step explanation:
Let x,y, and z be the numbers of free throws, two-point field goals and three-point field goals she made.
As she scored a total of 863 points, so
x+2y+3z=863...(i)
As the number of two-point field goals that Rebecca made was 80 less than double the number of three-point field goals she made, so
2z-y=80
Or y=2z-80...(ii)
As the number of free throws (each worth one point) she made was 13 less than the number of two-point field goals she made, so
y-x=13
-x= 13-y
-x= 13-(2z-80)
-x= 93-2z
x=2z-93...(iii)
Now, put the values from equation (ii) and (iii) to equation (i), we have
(2z-93)+2(2z-80)+3z=863
2z-93+4z-160+3z=863
9z=863+93+160=1116
z=1116/9=124
From equation (ii)
y=2x124-80=168
and from equation (iii)
x=2x124-93=155.
Hence, the number of free throws, two-point field goals, and three-point field goals Rebecca Smith made during the 2006 regular season are 155, 168, and 124 respectively.

what is x? in the equation x-21=6
Answer:
27
Step-by-step explanation:
You would turn the equation around, so it is 21+6=27 and checking, 27-21=6
Answer:
x = 27
Step-by-step explanation:
x- 21 = 6
add 21 to both sides:
x = 27
Check your work by substitution:
27 - 21 = 6
6= 6
x = 27

Question: A group of workers is harvesting berries at a constant rate. An equation that represents the total number of baskets of berries the workers picked over a period of time, in hours, is y = 7x + 15.
A) What are the slope and the y-intercept for the equation?
B) Which term represents the total number of baskets of berries the workers picked over a period of time?
C) What are the rate of change and the initial amount? Explain the meaning of the rate of change and the initial amount for the situation.
Answer:
(a) The slope and the y-intercept are 7 and 15
(b) y represents the total number of baskets of berries the workers picked over a period of time
(c) The rate and the initial amounts are 7 baskets/hour and 15 baskets
Step-by-step explanation:
Answer:
A. the slope of the equation is 7 and y-intercept is 15
B. the term "y" represents the total
C. The rate of change is 7x and the initial amount is 15. The rate of change means the "thing" (or variable) that keeps on changing and here it is the 7x. This means that every hour, the workers pick 7 baskets and this number will change based on the hours, which can is represented by the x. The 15 is our initial amount of baskets we had before starting because it is unchanging, it is our initial amount.
Explanation for A & B:
A. This equation is written in slope-intercept form which is, y=mx+b the slope is represented by the "m" and the y-intercept is represented by the "b". In simpler words, slope=m and y-intercept=b
B. When we take our given amount which is 15 baskets (y) and add it to our slope (7x) or the amount that changes based on time
we will get our total y, which represents the total amount of baskets

write the equation x+y=6y into standard form
Answer:
x - 5y = 0
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
x + y = 6y ( subtract 6y from both sides )
x - 5y = 0 ← in standard form
Answer: x-5y=0
Step-by-step explanation:
x+y=6y
6y-y
X=5y
X-5y=0
What does negative 3 over 5 > −2 indicate about the positions of negative 3 over 5 and −2 on the number line?
So,
Ignore the negatives and just make them positives.
For now.
Then, you look at 3/5 and say... it's 3 ticks towards the number five,
meaning it's between 4 and 5. After you do that whats happens is you place back the negatives and you have -3/5 and -2.
-2 < 5 and -2 < 4
Meaning it goes more to the left.

is 192 rational , why is it?
Answer: 192 IS IRRATIONAL. I HOPE THIS ANSWER HELPS.
Step-by-step explanation:
It is an irrational number if it is not a perfect square. Since 192 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 192?" will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.

graph the inequality plz help me solve this and explain how plzzzzzz x-y <4
Answer:
Step-by-step explanation:
first you have to get the inequality to a point where you can actually graph it
to do this you have to get the x to the same side of the less than symbol
you do this like any other equation, subtract x from the left and right sides because whatever you do to one side, you do to the other
this leaves you with -y < -x + 4
you have to multiply the entire thing by -1 because y cannot be negative
this gives you y < x - 4, now you can graph it
because x is isolated you just have to graph y < -4 like so
