None of Chen and Mia have got the solution right for the given expression.

It is given that two students are asked to write an equivalent expression for (5v - 3 ) × 2.

We have to find out that which of the both students have got it correct ?

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , division , etc.

As per the question ;

The expression is (5v - 3 ) × 2.

Let's solve this equation to find out who of Chen and Mia is correct.

So ;

(5v - 3) × 2

= (5v  × 2) - (3 × 2)

= 10v - 6

So ; None of Chen and Mia is correct.

Thus , none of Chen and Mia have got the solution right for the given expression.

Answer: Both Chen, and Mia are correct.

Step-by-step explanation:

The expression they gave us:

(5v^-3)^2.

Mia: 25/v^e

Chen: 25v^1

Now,

5v^-3)^2

Step 1: (5v^-3).= (5^2)v^3x2
Step 2: (5x5)v^3x2=25v^3x2
Step 3: 25v^-6. As you see Chen is correct. But..

Step 4: 25/1 x 1/v^6= 25/v^6

That also makes Mia to be correct.

So, in this problem there are two answers.

= 25v^-6, and 25/v^6.

Using translation concepts, the y-coordinate of R' will be of -10.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

For this problem, the rule is given by:

(x,y) -> (x + 4, y - 7)

y -> y - 7 means that for the image, the 7 is subtracted from the y-coordinate of the pre-image. The y-coordinate of R is of -3, -3 -7 = -10, hence the y-coordinate of R' will be of -10.

Answer:

x = 8

Step-by-step explanation:

Solve for x:

-2 x + 16 = 4 (x/4 - 2)

Put each term in x/4 - 2 over the common denominator 4: x/4 - 2 = x/4 - 8/4:

-2 x + 16 = 4 (x/4 - 8/4)

x/4 - 8/4 = (x - 8)/4:

-2 x + 16 = 4 ((x - 8)/4)

(4 (x - 8))/4 = 4/4×(x - 8) = x - 8:

-2 x + 16 = x - 8

Subtract x from both sides:

(-2 x - x) + 16 = (x - x) - 8

-2 x - x = -3 x:

-3 x + 16 = (x - x) - 8

x - x = 0:

-3 x + 16 = -8

Subtract 16 from both sides:

(16 - 16) - 3 x = -16 - 8

16 - 16 = 0:

-3 x = -16 - 8

-16 - 8 = -24:

-3 x = -24

Divide both sides of -3 x = -24 by -3:

(-3 x)/(-3) = (-24)/(-3)

(-3)/(-3) = 1:

x = (-24)/(-3)

The gcd of -24 and -3 is -3, so (-24)/(-3) = (-3×8)/(-3×1) = (-3)/(-3)×8 = 8:

The number of pages read by Soua in 10 minutes are 26.7 pages.

It is given in the question that Soua can read 8 pages in 3 minutes.

We have to find the number of pages that she will she read in 10 minutes.

We will use the unitary method for this question.

The method by which we find out the value of one unit and further use it to find the value of multiple units is known as the unitary method.

Pages read by Soua in 1 minute = 8/3 pages

Hence, we can write,

Pages read by Soua in 10 minutes = 10*(8/3) = 80/3 pages = 26 and(2/3) pages = 26.667 pages ≈ 26.7 pages.

Step-by-step explanation:

10x-2x=8x, and since the 23 was in the parenthesis that was being subtracted, then the 23 gets subtracted.

By reading the given graph, we conclude that:

-8*f(1) - 4*g(4) = -8

Here we have two graphed functions, f(x) which is the blue one, and g(x) which is the purple one.

We want to find the value of:

-8*f(1) - 4*g(4)

So first we need to find the values of f(1) and g(4), and to do that, we need to use the given graphs.

On the graph we can see that:

f(1) = -2

g(4) = 6

Replacing that in the expression we get:

-8*f(1) - 4*g(4) = -8*-2 - 4*6 = 16 - 24 = -8

Then, by reading the given graph, we conclude that:

-8*f(1) - 4*g(4) = -8

The least amount of money you can spend to buy the same number of candles and mints is $125.

The prime factorization of 12 and 15 is:

12= 2*2*3

15= 2*5*5

Now the factor of both appears in both number's factorization so least common multiple is:

LCM of 12 and 15 = 2*2*3*5*5=300

It is given that candies come in packs of 12 and mints in packs of 50.

Hence, the total quantity of packs of each thing is:

Candles: 300÷12=25

Mints: 300÷50=6

We can the slope of the line using:

m = (y 2 - y 1)/ (x 2 - x 1) where, m is the slope of the line.

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

Any two different points on a line can be used to calculate the slope of any line. The ratio of "vertical change" to "horizontal change" between two different locations on a line is calculated using the slope of a line formula. A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes.

The total amount that she will have to pay back at the end of 10 months is $11,385.864.

We have Sophia .who borrowed $11,020.

We have to determine the total amount that she will have to pay back at the end of 10 months.

The Simple interest can be calculated using the formula -

S.I. = (P x R x T)

where -

P = Principle amount

R = Rate of interest

T = time in years

According to the question -

P = $11020

R = 4%

T = 10 months = 0.83 years

Therefore -

Interest = (P x R x T) = (11020 x 0.04 x 0.83) = $365.864

Now -

Interest = Total amount - Principle

Total Amount = Interest + Principle = 11020 + 365.864 = $11,385.864

Hence, the total amount that she will have to pay back at the end of 10 months is $11,385.864.

If we have to find the remaining material that has been left we must find the difference between the two i.e. used and purchased material by simply subtracting them.

So, Material purchased = 3 yards

      Material used = 5/8 yards
