Answer:

(-5 x)/2

Step-by-step explanation:

Simplify the following:

-6 (x/4 - (2 x)/3 + (5 x)/6)

Put each term in x/4 - (2 x)/3 + (5 x)/6 over the common denominator 12: x/4 - (2 x)/3 + (5 x)/6 = (3 x)/12 - (8 x)/12 + (10 x)/12:

-6(3 x)/12 - (8 x)/12 + (10 x)/12

(3 x)/12 - (8 x)/12 + (10 x)/12 = (3 x - 8 x + 10 x)/12:

-6(3 x - 8 x + 10 x)/12

The gcd of -6 and 12 is 6, so (-6 (3 x - 8 x + 10 x))/12 = ((6 (-1)) (3 x - 8 x + 10 x))/(6×2) = 6/6×(-(3 x - 8 x + 10 x))/2 = (-(3 x - 8 x + 10 x))/2:

(-1 (3 x - 8 x + 10 x))/2

3 x - 8 x + 10 x = 5 x:

Answer: (-5 x)/2

Answer:

w=1

Step-by-step explanation:

8w-12=-4

8w =-4+12

8w=8

8w/8=8/8

w=1

Mark as brainliest

Answer:

Well first we have to know what -12 is -4. So I know that 8 subtracting 12 is -4 already but, i am explaining to your knowlege so  here I go.

What we can do is add 12 to -4 and it will equal what _-12=-4  

So -4+12=8

Since the variable is with 8, we have to find what the variable w is. So 8x_=8?

Thats obvious right? 8x1=8!

So 8w-12=-4 = 8x1=8-12=-4

Hope this helps and if it helps enough pls mark as brainliest!

Step-by-step explanation:

Equivalent to 175 cents

She has 5 dimes and 25 nickels

====================================================

Explanation:

n = number of nickels

d = number of dimes

n+d = 30 since she has 30 coins of just these two types

n = 5d because she has five times as many nickels compared to dimes

-----------------

We'll use substitution to solve this system

n+d = 30

5d+d = 30 ... replace n with 5d

6d = 30

d = 30/6 ... divide both sides by 6

d = 5

Sophie has 5 dimes

n = 5d

n = 5*5 ... plug in d = 5

n = 25

Sophie also has 25 nickels

(5 dimes) + (25 nickels) = 30 coins total

This confirms we have the right coin counts.

-------------------

Let's find the value of each stack of coins

1 nickel = 5 cents

25 nickels = 125 cents (multiply both sides by 25)

1 dime = 10 cents

5 dimes = 50 cents (multiply both sides by 5)

(5 dimes) + (25 nickels) = (50 cents) + (125 cents) = 175 cents

175 cents = (175/100) dollars = 1.75 dollars

Concepts Used:                                                                                                    

Finding x:_____________________________________________            

From the Exterior angle property, we know that the measure of an exterior angle is the sum of the 2 opposite interior angles

So, using the property

(3x-10) = (25) + (x + 15)

3x - 10 = 25 + x + 15

3x - 10 = 40 + x

3x-x - 10 = 40              [subtracting x from both sides]

2x - 10 = 40

2x = 50                        [adding 10 on both sides]

x = 25                          [dividing both sides by 2]

Hence, the value of x is 25

Step-by-step explanation:

Hello!

The new value is $ 22,9425 or just $ 23 in a more simplified size.

We need to calculate 25% of 30.59.

We will do this by turning 25 into tenths:

Now, we subtract that from 30,59.

30,59 - 7,6475

= 22,9425

So, the new value is $ 22,9425 or just $ 23 in a more simplified size.

Answer:

[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 2x + 1 ( subtract 1 from both sides )

y - 1 = 2x ( divide both sides by 2 )

[tex]\frac{y-1}{2}[/tex] = x

Change y back into terms of x with x = [tex]f^{-1}[/tex](x) , thus

[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]

Answer:

Your answers should be a = 135 adult tickets and s = 186 student tickets.

Step-by-step explanation:

1. Solving for variable s by manipulating variable a:

a + s = 321

a = 321 - s (subtract s to the other side to get a by itself)

$3.50(321-s) + $2.50s = $937.50 (substitution from step 2)

$1123.50 - $3.50s + $2.50s = $937.50 (distributive property)

$1123.50 - $1.50s = $937.50 (combine like terms)

-$1.00s = -$186 (subtraction property of equality)

s = 186 student tickets.

2. Solving for variable a by manipulating variable s:

a + s = 321

s = 321 - a

$3.50a + $2.50(321-a) = $937.50

$3.50a + $802.50 - $2.50 a = $937.50

$1.00a = $135

a = 135 adult tickets.

If you plug both numbers into the original equations, they should come out to be true equations. 135 + 186 = 321 and $472.5 + $465 = $937.5, so these two numbers are your answers for a and s accordingly.

Using the elimination method, we need to eliminate one of the variables by a process of subtraction or addition depending on the case. We can use multiplication or division before eliminating in order to eliminate.

a + s = 321

3.50a + 3.50s = 1123.50 (multiply entire equation by 3.50 in order to eliminate variable a by subtraction)

Now, we can use elimination:

3.50a + 3.50s = 1123.50

3.50a + 2.50s = 937.50

0a + 1s = 186, or s = 186 student tickets.

The same process can be used to solve for variable a. Your answers should be a = 135 adult tickets and s = 186 student tickets.

Answer:

x = 10

Step-by-step explanation:

Step 1: Define

f(x) = -3x + 51

g(x) = 3x - 9

f(x) = g(x)

Step 2: Set up equation

f(x) = g(x)

-3x + 51 = 3x - 9

Step 3: Solve for x

51 = 6x - 9

60 = 6x

x = 10

Step 4: Check

f(10) = -3(10) + 51

f(10) = -30 + 51

f(10) = 21

g(10) = 3(10) - 9

g(10) = 30 - 9

g(10) = 21

f(10) = g(10) = 21

The choice which defines the piecewise function shown in the graph is; Choice B.

For the line originating from the center and plotted towards the right (i.e Positive x-axis)

We can conclude that the line can be represented by the function; f(x) = -x/2 and slope = -1/2 where; x>= 0 due to the solid dot

For the line whose y-intercept is at point, (0, -2), and is plotted towards negative x; we have;

We can conclude the equation of the line can be represented by the function; f(x) = -x -2 where slope = -1, and domain; x < 0

Ultimately, the aggregate of both functions give s the required piecewise function as represented in Choice B.

Answer:

x = [tex]\frac{3+2y}{5y-2}[/tex]

Step-by-step explanation:

Given

y = [tex]\frac{2x+3}{5x-2}[/tex] ← multiply both sides by (5x - 2)

y(5x - 2) = 2x + 3 ← distribute left side

5xy - 2y = 2x + 3 ( add 2y to both sides )

5xy = 2x + 3 + 2y ( subtract 2x from both sides )

5xy - 2x = 3 + 2y ( factor out x from each term on the left side )

x(5y - 2) = 3 + 2y ← divide both sides by (5y - 2)

x = [tex]\frac{3+2y}{5y-2}[/tex]

Answer:

t = 4 + 6n

Step-by-step explanation:

a = 10

d = 6

in general

tn = a + (n-1)*d

tn = 10 + (n-1)*6

tn = 10 + 6n - 6

tn = 4 + 6n

So if n = 5 then

t5 = 4 + 6*5

t5 = 4 + 30

t5 = 34 which agrees with your givens.

If X = 37.5% of 20% of 48 and Y = 14.28% of  27.27% of 77, then  X>Y.

The first step is to determine the value of X.

X = 37.5% of 20% of 48

X = 0.375 x 0.2 x 48 = 3.6

The second step is to determine the value of Y.

Y = 14.28% of  27.27% of 77

Y = 0.1428 x 0.2727 x 77 = 3

Note that:  

> means greater than

< means less than

≥ means greater than or equal to  

≤ less than or equal to

Based on the above calculations, x > y.
