Answer:

She can make 18 servings.

Step-by-step explanation:

We can simply multiply 3 by 6 to get the number of servings.

This is the same as dividing 3 by 1/6 since dividing is the same as multiplying the reciprocal.

all triangles are 180 always. make a equation 2x+x+x+8 then combine like terms so it will be 4x+8 then divide by 4 on bith sides x=2

The positive graph of y = 2x + 5 changes to the negative graph which moves downward from left to right when the slope is changed to -2.

Slope of a line is defined as the difference in the y coordinates divided by the difference in the x coordinates of two points.

Slope of a line is usually denoted by the letter m.

First let us take the graph of y = 2x + 5.

Take x intercept and y intercept of this graph.

x intercept is the point where line touches X axis and y intercept is the point where line touches Y axis.

From the equation of the line, y intercept = 5

So we get a point (0, 5)

Now to find x intercept, let y = 0 in the equation, then x = -2.5

So we get another point (-2.5, 0)

So the line y = 2x + 5 passes through the points (0, 5) and (-2.5, 0).

Now if the slope changed to -2, equation becomes y = -2x + 5.

y intercept is same.

So one point of the line will be (0, 5)

To find x intercept, let y = 0 in the second equation, then x = 2.5

So the second line passes through the points (0, 5) and (2.5, 0)

That is, the graph which goes upward from left to right changed to the graph downward from left to right.

Hence, when the slope changed to -2, the graph goes downward from left to right.

Step-by-step explanation:

The given expression is ( 3x - 5 ) - ( 5x + 1 )

We have to simplify the given expression

First we will open the bracket having negative notation outside.

( 3x - 5 ) - 5x - 1

3x - 5 - 5x - 1

Now we will collect the similar terms together.

3x - 5x - 5 -1

-2x - 6

So the simplified form of the expression is (-2x - 6)

Step-by-step explanation:

Answer:

-55

Step-by-step explanation:

The simplified expression is 3(x√2 + √x), which means that the answer is (C) x²√2.

In mathematics, an expression is a combination of numbers, variables, operators, and functions that can be evaluated to produce a numerical value or another mathematical object such as a polynomial, equation, or inequality.

We can simplify the given expression by factoring out the greatest perfect square factor under each square root symbol. For the first term, √18x³, we can factor out √9x², which is 3x√2. For the second term, √9x, we can factor out √9, which is 3. Thus, we have:

√18x³ + √9x = √(9x²⋅2x) + √(9⋅x) = 3x√2 + 3√x

We can then factor out 3 from both terms:

√18x³ + √9x = 3(x√2 + √x)

Therefore, the simplified expression is 3(x√2 + √x), which means that the answer is (C) x²√2.

Answer:

Cups of 120oz sold = 17

Cups of 160oz sold = 25

Cups of 200oz sold = 13

Step-by-step explanation:

We know that:

a 120z cup of coffee costs $1.65

a 160z cup costs $1.85

a 200oz cup cost $1.95

Let's define the variables:

A = # of 120z cups that she sold

B = # of 160oz cups that she sold

C  = # of 200oz cups that she sold.

We know that:

"Reba served 55 cups of coffee"

A + B + C = 55.

"emptying six 1440z brewers while"

A*120oz + B*160oz + C*200oz = 6*1440oz

"collecting a total of $99.65"

A*$1.65 + B*$1.85 + C*$1.95 = $99.65

Then we have a system of equations:

A + B + C = 55

A*120oz + B*160oz + C*200oz = 6*1440oz

A*$1.65 + B*$1.85 + C*$1.95 = $99.65

To solve this, the first step is to isolate one of the variables in one of the equations, let's isolate A in the first one:

A = 55 - B - C

Now we can replace that into the other two equations:

(55 - B - C)*120oz + B*160oz + C*200oz = 6*1440oz

(55 - B - C)*$1.65 + B*$1.85 + C*$1.95 = $99.65

Now we can rewrite those equations as:

B*40oz + C*80oz = 8640oz - 55*120oz  = 2040oz

B*$0.20 + C*$0.30 = $99.65 - 55*$1.65 = $8.90

Now we have the system:

B*40oz + C*80oz = 2040oz

B*$0.20 + C*$0.30 = $8.90

Now we need to isolate another variable in one of the equations, let's isolate B in the first one:

B = 2040oz/40oz - C*80oz/40oz = 51 - 2*C

Now we can replace this in the other equation and get:

(51 - 2*C)*$0.20 + C*$0.30 = $8.90

Bow we can solve this for C.

$10.20 - C*$0.40 + C*$0.30 = $8.90

$10.20 - $8.90 = C*$0.10

$1.30 = C*$0.10

($1.30/$0.10) = C = 13

Now we can replace this in the equation:

B = 51 - 2*C = 51 - 2*13 = 25

And for A, we had:

A = 55 - B - C = 55 - 25 - 13 = 17

Then:

Cups of 120oz sold = 17

Cups of 160oz sold = 25

Cups of 200oz sold = 13

Answer:

[tex]a= \frac{k}{9b+4}[/tex]

Step-by-step explanation:

In this question, you would solve for "a".

Solve:

K = 4a + 9ab

Since we have our "a" on the same side, we can factor it out from the variables:

K = a(9b + 4)

To get "a" by itself, we would have to divide both sides by 9b + 4:

K/9b+ 4 = a

Your answer would be K/9b+ 4 = a

It would look like this: [tex]a= \frac{k}{9b+4}[/tex]

Answer:

it's a = K / 4 + 9b
