Answer:

4x + 2y

Step-by-step explanation:

1. 4x - 3(x - 2y) + 1/2(6x - 8y)

4x - 3x + 6y + 3x - 4y

4x + 2y

2. 4x - 3(x - 2y) + (1/2)(6x - 8y) =

4x - 3x + 6y  + 3x - 4y =

4x + y(6 - 4) = 4x + 2y = 2(2x + y)

Answer:

72 dentists

Step-by-step explanation:

In this case, we can multiply 80 by 9/10 or .9 to get our answer.

If we were to multiply by 9/10 it would look like this:

[tex]80 * \frac{9}{10} \\\frac{720}{10} = 72[/tex]

But, if we were to multiply by .90 (remember that 9/10 = .9) it would look like this:

[tex]80(.90) = 72[/tex]

Therefore, if 9 out of 10 dentists recommended PurWhite toothpaste and 80 were surveyed then 72 out of the 80 would have recommended it.

I hope this helps!!

Answer:

7

Step-by-step explanation:

First expand 2/3 (9x-6) = 4 (x+2)+ 2 By doing 2/3 (9x - 6)/3

Which gives you 2/3 (9x - 6)

Then you factor it 2/3 (9x - 6) 6 (3x - 2) get 6 (3x - 2) / 3

then you divide 6/3 with 2

Getting 2 (3x - 2)

The use the distributive law

2 x 3x - 2 x 2

simplify the equation

6x - 4

expand 4 (x +2) + 2:   4x + 10

which then equals 6x-4=4x+10

add 4 to both sides

6x-4+4=4x+10+4

simplify

6x=4x+14

subtract 4x from both sides

simplify again

2x=14

divide both sides by 2

2x/2 = 14/2

simplify one last time and get the answer

Given :

Two equations :

y = t³

x = t + 5

To Find :

Rectangular equation formed by eliminating the parameter.

Solution :

Putting value of t from second equation to first equation.

We get :

[tex]y = ( x-5)^3[/tex]

Also, t from equation first :

[tex]t = \sqrt[3]{y}[/tex]

Putting the value of t and equation two, we get :

[tex]x = \sqrt[3]{y}+5[/tex]

Therefore, rectangular equation is formed by eliminating the parameter is :

y = ( x - 5)³ and x = ∛y + 5 .

The rectangular equation is y = (x - 5)³ which is obtained from the parametric equations y = t³ and x = t + 5 option (3) y = (x - 5)³ is correct.

A parametric equation in mathematics specifies a set of numbers as functions of one or more independent variables known as parameters.

The options are:

The parametric equations are:

y = t³

x = t + 5

From the second equation that is x = t + 5

Take the value of t and plug in the equation y = t³:

t = x - 5

y = (x - 5)³

The above equation represents a cubic equation.

Thus, the rectangular equation is y = (x - 5)³ which is obtained from the parametric equations y = t³ and x = t + 5 option (3) y = (x - 5)³ is correct.

Answer:

19 batches

Step-by-step explanation:

Given that:

Total number of cups of sugar = [tex]12\frac{2}{3}[/tex]

Amount of sugar used in one batch = [tex]r[/tex]

Number of batches that can be made by Tyra with the amount of sugar that is available with Tyra can be calculated by dividing the total number of cups of sugar available with Tyra with the amount of sugar to be used in one batch.

i.e.

Number of batches = [tex]12\frac{2}{3} \div r[/tex]

Also, if we put the value:

[tex]r=\frac{2}{3}[/tex]

We have to find the number of batches of cookies that can be made by Tyra.

Solution:

First of all, let us have a look at the formula to convert the mixed fraction into fractional number.

[tex]a\dfrac{b}{c} = \dfrac{a\times c + b}{c}[/tex]

Therefore,

[tex]12\dfrac{2}{3} = \dfrac{12\times 3 + 2}{3} = \dfrac{38}{3}[/tex]

Number of batches:

[tex]\dfrac{38}{3} \div \dfrac{2}{3}\\\Rightarrow \dfrac{38}{3} \times \dfrac{3}{2}\\\Rightarrow \bold{19}[/tex]

Therefore, 19 batches can be completed.

Answer:

26kg

Step-by-step explanation:

Firstly, we need to find 1/5 of 65kg so we do: 65/3=13

Then, to find 3/5 of 65kg we multiply 13*3 to get 39

Lastly, we subtract 39 from 65 to get 26kg

Answer:  4 servings

4 cups of milk = 8 servings

2 cups of milk = 4 servings

I divided both sides by 2 to change "4 cups milk" into "2 cups milk".

The reason why I want 2 cups of milk is because the chart you're given shows 1 pint is 2 cups.

Therefore, 1 pint of milk will get you 4 servings.

Answer:

11x-8

Step-by-step explanation:

First you expand 3(x-2):  3x-6

3x-6+2(4x-1)

then expand  2(4x-1): 8r - 2

3x-6+8x-2

and then simplify 3x - 6 + 8x -2: 11x - 8

11x - 8

so the answer is 11x-8

Answer:

y>2/3x+3

Step-by-step explanation:

Answer and Step-by-step explanation:

The answer is the third option, or:

[tex]y > \frac{2}{3} x + 3[/tex]

This is because the line has a rise of 2 and a run of 3 (so a slope of 2/3)

and Everything is filled in above the line, so y is greater than the the values on the line and below the line.

Answer:

72

Step-by-step explanation:

Based on the table, the left and the right side have a pattern. When 3 is added to the left side, the right side is multiplied by 6. Since 12 multiplied by 6 is 72, the missing number is 72.

Answer:

p=7

Step-by-step explanation

both n and 4 are in both so p will have to be the same thing as 7 in order to be equal

The value of p that makes the expressions 4(n+7) and (n+p)4 equivalent is p = 7.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To make the expressions 4(n+7) and (n+p)4 equivalent, we need to distribute the 4 in the second expression, which gives us:

(n+p)4 = 4n + 4p

Now we can set this expression equal to 4(n+7) and solve for p:

4n + 4p = 4(n+7)

Simplifying both sides:

4n + 4p = 4n + 28

Subtracting 4n from both sides:

4p = 28

Dividing both sides by 4:

p = 7

Therefore,

The value of p that makes the expressions 4(n+7) and (n+p)4 equivalent is p = 7.

Answer:

3.37

Step-by-step explanation:

Given that :

CUNMULATIVE GPA for 4 semesters :

First 3 semesters:

Cummulative GPA = 3.24

Number of courses = 46

4th semester:

Cummulative GPA = 3.86

Number of courses = 12

Cummulative GPA for all 4 semesters:

Sum of product of Cummulative GPA and number of courses / sum of courses

= [(3.24 * 46) + (3.86 * 12)] ÷ (46 + 12)

= (149.04 + 46.32) / 58

= 3.3682758

= 3.37

Tessa's cumulative GPA for all 4 semesters is 3.37 and this can be determined by using arithmetic operations.

Given :

Given that cumulative GPA for 3 semesters was 3.24 for 46 courses and the fourth semester GPA was 3.86 for 12-courses then the cumulative GPA for all 4 semesters will be:

[tex]=\dfrac{(3.24\times 46)+(3.86\times 12)}{(46+12)}[/tex]

Step-by-step explanation:

the sentence of the rectangle are 3cm and 4cm what is the length of the diagonal

Answer: 25%

Step-by-step explanation:

Given: A rectangle has length 4 inches and width 2 inches.

Area = Length x width

= 4 inches x  2 inches

= 8 square inches

If length is reduced by 50% , then length [tex]=0.5\times4=2\text{ inches}[/tex]

If width is reduced by 50% , then length [tex]=0.5\times2=1\text{ inch}[/tex]

Reduced area = (reduced length) x (reduced width)

= 2 inches x 1 inch

= 2 square inches

The percentage of the area of the rectangle be reduced :-

[tex]\dfrac{\text{Reduced area}}{\text{Original area}}\times100 \\\\=\dfrac{2}{8}\times100\% \\\\=25\%[/tex]

Hence, the percent of the area of the rectangle be reduced = 25%

Answer:

24.33 feet

Step-by-step explanation:

The flower bed, the ladder and the house form a right angled triangle where the length of the ladder is the hypotenuse side.

Let L = length of ladder, H = height of house = 24 feet and l = length of flower bed = 4 feet.

Using Pythagoras' theorem,

L² = H² + l²

So, L = √(H² + l²)

substituting the values of the variables, we have

L = √[(24 ft)² + (4 ft)²]

L = √[576 ft² + 16 ft²]

L = √[592 ft²]

L = 24.33 ft

The ladder must be at least 24.33 feet long to reach the top and be out of the flower bed
